Description
e t - 1 _ TIME INFORMATION DISPLAY SYSTEM
BACKGROUND OF THE INVENTION
The present invention relates to a time information display system capable of appending relative date and time with respect to a date and time expression character string on the basis of present date and time to display the time information.
Generally, forming of documents on computers is very recently popularized. Also, exchanging of documents by using electronic mails is popularized.
There are many cases that broadcasting notifications such as notifications as to holding of ineetings are issued by way of electronic mails. In this case, such an expression "meeting will be held tomorrow" may be used in subjects and the like of mail documents.
However, a mail receiving person does not always read a mail document on the date and time when a mail sending person sends this electronic mail. Thus, the mail receiving person can hardly judge the relevant date and time by merely viewing the subject. As a consequence, the mail receiving person may judge this relevant date/time by confirming the date/time when the mail document was actually sent. On the other hand, in order to clearly define the relevant date/time, the mail sending person requires to clearly write the relevant date/time in the subject. These actions may cause certain probabilities that both the mail sending person and the mail receiving person may mistakenly recognize incorrect date and time.
To solve these problems, JP-A-11-96146 has proposed such a technique that while the time difference is calculated based upon both the inputted time information and the previously-registered schedule data, such an expression "several days are still left"
is displayed.
Also, JP-A-6-203031 has proposed the following technique. That is, such relative date/time expressions as "Wednesday in last week" and "today" are converted into the absolute date/time expressions corresponding thereto, and the converted absolute date/time expressions are displayed.
Furthermore, JP-A-6-266723 describes the document forming apparatus which converts the relative time into the absolute time, and also, converts the absolute time into the relative time based upon the document forming time.
However, in the above-described technique disclosed in JP-A-11-96146, since the time difference with respect to the schedule data which has been previously registered by the user is calculated, there are many opportunities that when the first electronic mail as to the notification of holding of the meeting is received, this meeting has not yet been registered in the above schedule date. As a result, after the user has registered the schedule data, the user is newly required to confirm the content of the electronic mail. Also, since the time is calculated with respect to the previously registered schedule data, there is a certain possibility that another time difference is calculated with respect to such a schedule data different from this meeting to display this calculated time difference.
Also, in the above-described technique disclosed in JP-A-6-203031, when the document is inputted, the relative date/time is converted into the relevant absolute date/time. Therefore, in such a case that an electronic mail in which a relative date/time expression is used in a subject, or the like is transmitted, the mail receiver requires to confirm an absolute date/time corresponding thereto based upon a calendar. Also, in the case that a mail input person does not immediately transmit an electronic mail, if the mail input person forms a document by considering transmission date/time, then there is such a problem that this transmission date/time is converted to such an absolute date/time which is different from the actual absolute date/time.
Also, in the above-explained technique described in the JP-A-6-266723, while the document forming time is used as the reference time, the absolute time may be converted into the relative time so as to display the converted relative time. However, in the case that the unsealing time of the mail reading person is different from the document forming time of the mail sender, there is a problem that no specific care is taken as to the display of the time expression described in the document.
SUMMARY OF THE INVENTION
An object of the present invention is to avoid an erroneous recognition of the date and time, which is caused by recognition shifts occurred between a document forming person and a document reading person, and furthermore, is to reduce a work load when a document is formed by this document forming person by executing a process operation in such a manner that all of date/time expressions which have been previously entered are automatically converted into relative date/time based upon present date/time, and then, the automatically converted relative date/time is appended to original expressions thereof so as to display both the original expressions and the relative date/time appended thereto.
To solve the above-described problems, a time information display system, according to the present invention, is featured by comprising: a storage unit for storing thereinto all of character strings of document data such as a subject of document data and forming date/time of the document data; a date/time character string detecting unit for detecting as to whether or not a character string indicative of date/time is contained with respect to a character string of the document data stored in the storage unit;
a relative date/time detecting unit operated in such a manner that when a date/time expression is detected by the date/time character string detecting unit, the relative date/time detecting unit detects as to whether or not a date/time character string of the document data stored in the storage unit is equal to a relative date/time expression; an absolute date/time converting unit for converting the relative date/time expression detected by the relative date/time detecting unit into an absolute date/time expression; a storage unit for storing thereinto the absolute date/time character string converted by the absolute date/time converting unit; a difference date/time calculating unit for calculating difference date/time between present date/time and the absolute date/time expression stored in the storage unit; a relative date/time converting unit for converting the calculated difference date/time calculated by the difference date/time calculating unit into relative date/time with respect to the present date/time; and a relative date/time expression storage unit for storing thereinto the relative date/time character string converted by the relative date/time converting unit.
In the case that a date/time expression is judged, while character strings of expressions which may be predicted as the date/time expressions are previously registered, a judgment is made as to whether this date/time expression is made coincident with a relative date/time expression, or an absolute date/time expression. For instance, while expressions such as "tomorrow" and "next week" are previously stored as the fixed character strings of the relative date/time expressions and also expressions such as "numeral +
day" are previously stored as the fixed character strings of the absolute date/time expressions, if a range of character strings is registered which are cut out in correspondence to these relative date/time expressions and absolute date/time expressions, then only a date/time expression can be cut out. This cut-out character string and a position where this character string is cut out from an original document are stored into the storage unit in correspondence with each other, and then, a converting process operation is carried out. It should be noted that the judgment as to whether the character string is made coincident with the relative date/time expression, or the absolute date/time expression may be newly confirmed after this character string has been cut out. Alternatively, when the character string is cut out, the sort of such fixed character string coincident with this cut-out character string is registered in correspondence with this cut-out character string. Then, the above-described judgment may be carried out in accordance with these registered data. All of the registered relative date/time character strings are converted into absolute date/time. This conversion operation from the relative date/time into the absolute date/time is carried out in such a manner that while the document forming date/time is employed as the reference date/time, this relative date/time is converted into the absolute date/time based upon a correspondence table between the relative character string and the difference value with respect to the reference date/time. The absolute date/time character string is merely left. As a result, such a correspondence table between the absolute date/time character strings and the original positions thereof within the document may be formed. Next, the absolute date/time character string is converted into the relative character string, while the present date/time is used as the reference date/time. This conversion from the absolute date/time character into the relative date/time character may be carried out by using the above-explained difference value correspondence table in a reverse manner. As to the present date/time used as the reference date/time, for example, in the case of a document file, such a date/time when this document file is firstly opened is used as this present date/time. In the case of an electronic mail, a delivering time thereof is employed as this present date/time. The reference date/time is displayed to a file/mail receiving person without giving any - 8 _ misunderstanding.
The relative date/time expression after being converted is displayed at a predetermined with respect to the absolute date/time expression character string before being converted, which is contained in the corresponding document data based upon the correspondence table between this predetermined position and the position of the original document.
Concretely such a clear display is made. That is, the relative date/time expression character string after being converted is inserted subsequent to the absolute date/time expression character string before being converted, while this relative date/time expression after being converted is parenthesized, or bracketed.
Alternatively, this relative date/time expression character string after being converted may be inserted into a space made between an upper line and a lower line as to the absolute date/time expression character string before being converted. As a result, a relationship between the character string before being converted and the character string after being converted can be grasped at a first glance. In addition, as to the character string before being converted, an emphasized character editing operation is carried out by providing an emphasized character editing unit by way of a font format converting operation such as boldface, italics, underlined formats, and color changed formats. In the case of a simple text document, a character string after being converted is appended to a character string before being converted by being inserted into character string data. In such a case of a document having an HTML
document structure, such a means may be employed in such a manner that a text figure is inserted into a predetermined position. Also, in the case that an original document is formed by using document forming software of the latest version, since data of absolute date/time is directly contained in a date expression, this value may be directly employed in a date/time expression converting operation.
The time information display system for displaying relative date and time, according to the present invention, may be similarly applied also to such an electronic mail document having a structure in which this document is subdivided into both a subject and a main body. In the case of an electronic mail, a relative date/time expression may be inserted into a subject of this electronic mail in order that the relative date/time may be discriminated from a subject list without opening a main body of this electronic mail. Alternatively, a color of the subject of this electronic mail may be changed in response to temporal propagations with respect to the present date/time.
While a date/time expression item is provided in an electronic mail system, expressions "today", "tomorrow", "the day after tomorrow", and the like may be indicated by way of a character and a symbol.
Other objects, features and advantages of the invention will become apparent from the following description of the embodiments of the invention taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE EMBODIMENTS
Referring now to drawings, the present invention will be described in detail.
Fig. 1 is a structural block diagram for indicating a structural arrangement of a time information display system according to the present invention. An information processing apparatus 100 is arranged by that a storage unit 105, a data input unit 101, a display unit 102, and a system clock unit 103 are connected to an information processing/calculating apparatus 104. This storage unit 105 stores thereinto a program used in the information processing apparatus 100. The information processing apparatus 100 may be realized by a general-purpose PC (personal computer) and a mail terminal. Both a document editing-purpose program 106 for a document date changing/editing operation, and data used to execute these functions have been previously stored into the storage unit 105 in connection to the above-described program for the information processing apparatus 100. This storage unit 105 is equipped with a document data storage unit 107, a system date/time storage unit 111, a difference date/time storage unit 112, an absolute date/time storage unit 113, a relative date/time storage unit 114, and a relative year/month/day conversion database 115.
Information as to document data which is extracted by the above-described document editing-purpose program 106 is stored into the document data storage unit 107. Concretely, document subject data, document forming date/time data, and document main body data are stored into the document data storage unit 107.
Present date and time are stored into the system date/time storage unit 111 when a program is initiated, or when an electric mail is received, while the present date/time are sequentially updated by the central processing/calculating apparatus 104 based upon a clock signal supplied from the document editing program 106.
In the absolute date/time storage unit 113, the following analysis result is entered. That is, since the document editing program 106 is executed, data stored in the document data storage unit 107 is analyzed, and a date/time expression analyzing process operation is carried out with respect to the document data, so that the analysis result is obtained. In the date/time expression analyzing process operation, a judgement is made as to whether or not an expression ..__ _ ....__ ~
........__ ...__.__.~_.___.._.,.___.,_.,_._._.~_-.

DETAILED DESCRIPTION OF THE EMBODIMENTS
Referring now to drawings, the present invention will be described in detail.
Fig. 1 is a structural block diagram for indicating a structural arrangement of a time information display system according to the present invention. An information processing apparatus 100 is arranged by that a storage unit 105, a data input unit 101, a display unit 102, and a system clock unit 103 are connected to an information processing/calculating apparatus 104. This storage unit 105 stores thereinto a program used in the information processing apparatus 100. The information processing apparatus 100 may be realized by a general-purpose PC (personal computer) and a mail terminal. Both a document editing-purpose program 106 for a document date changing/editing operation, and data used to execute these functions have been previously stored into the storage unit 105 in connection to the above-described program for the information processing apparatus 100. This storage unit 105 is equipped with a document data storage unit 107, a system date/time storage unit 111, a difference date/time storage unit 112, an absolute date/time storage unit 113, a relative date/time storage unit 114, and a relative year/month/day conversion database 115.
Information as to document data which is extracted by the above-described document editing-purpose program 106 is stored into the document data storage unit 107. Concretely, document subject data, document forming date/time data, and document main body data are stored into the document data storage unit 107.
Present date and time are stored into the system date/time storage unit 111 when a program is initiated, or when an electric mail is received, while the present date/time are sequentially updated by the central processing/calculating apparatus 104 based upon a clock signal supplied from the document editing program 106.
In the absolute date/time storage unit 113, the following analysis result is entered. That is, since the document editing program 106 is executed, data stored in the document data storage unit 107 is analyzed, and a date/time expression analyzing process operation is carried out with respect to the document data, so that the analysis result is obtained. In the date/time expression analyzing process operation, a judgement is made as to whether or not an expression ..__ _ ....__ ~
........__ ...__.__.~_.___.._.,.___.,_.,_._._.~_-.
indicative of relative date/time, and another expression representative of absolute date/time are contained with respect to the document data. It should be noted that these expressions are previously stored into the storage unit 105 as a list of previously-fixed expressions.
This list is constituted by an expression character string such as "tomorrow", "next week", and "numeral + day"; a sort of expression as to whether an expression character string corresponds to a relative date/time expression or an absolute date/time expression; and a correspondence relationship. That is, in this correspondence relationship, this expression character string is cut out by determining that how many characters are cut out before/after the relevant character string, or this expression character string is cut out based upon which condition. In the case that a date/time expression is contained, the central processing/calculating apparatus 104 judges as to whether or not such a character string corresponding to this date/time expression in the list is equal to the absolute date/time expression, or the relative date/time expression based upon the sort thereof.
When the relevant character string is equal to the absolute date/time expression, a character string is cut out as absolute date/time data based upon a cut-out logic of the corresponding character string in the list, and then, this cut-out character string is stored into the absolute date/time storage unit 113 in correspondence to positional data within the document.
When the relevant character string is equal to the relative date/time expression, while the above-described document forming date/time data is used as reference date/time, an absolute date/time is calculated by adding/subtracting a difference value at the forming date/time of the document based upon the relative year/month/day conversion database 115. This relative year/month/day conversion database 115 indicates a correspondence relationship between the relative character string which has been previously stored in the storage unit 105 and a difference value with respect to the reference date/time. The data which has been converted as the absolute date/time expression is stored into the absolute date/time storage unit 113 in correspondence with positional data within the document.
Next, the absolute display expression stored in the above-explained absolute date/time storage unit 113 is converted into a relative date/time expression based upon the above-described relative year/month/day conversion database 115 and the present date/time stored in the system date/time storage unit 111, and then, this converted relative date/time expression is stored into the relative date/time storage unit 114.
At this time, the correspondence relationship with respect to the positional data within the document is directly succeeded to be stored into the relative date/time storage unit 114.
Fig. 2A, Fig. 2B, and Fig. 2C are diagrams for showing contents of the relative year/month/day conversion database 115 employed in the storage unit 105 of the above-described information processing apparatus 100. Precisely, a relative year conversion table is shown in Fig. 2A, a relative month conversion table is indicated in Fig. 2B, and a relative day conversion table is represented in Fig. 2C.
In this relative year/month/day conversion database 115, relative date/time expression character strings corresponding to the difference date/time are stored, and are utilized when such a process operation for converting a relative date/time expression contained in the above-described document data into an absolute date/time expression is carried out, and also are utilized when such a process operation for converting an absolute date/time expression contained in the above-described document data into a relative date/time expression.
Subsequently, a description will now be made of a function of the document editing-purpose program 106 executed in the image processing apparatus 100 with employment of the above-described arrangement.
Fig. 3 is a flow chart for describing a relative date/time expression processing operation which is executed with respect to an electronic mail.
This list is constituted by an expression character string such as "tomorrow", "next week", and "numeral + day"; a sort of expression as to whether an expression character string corresponds to a relative date/time expression or an absolute date/time expression; and a correspondence relationship. That is, in this correspondence relationship, this expression character string is cut out by determining that how many characters are cut out before/after the relevant character string, or this expression character string is cut out based upon which condition. In the case that a date/time expression is contained, the central processing/calculating apparatus 104 judges as to whether or not such a character string corresponding to this date/time expression in the list is equal to the absolute date/time expression, or the relative date/time expression based upon the sort thereof.
When the relevant character string is equal to the absolute date/time expression, a character string is cut out as absolute date/time data based upon a cut-out logic of the corresponding character string in the list, and then, this cut-out character string is stored into the absolute date/time storage unit 113 in correspondence to positional data within the document.
When the relevant character string is equal to the relative date/time expression, while the above-described document forming date/time data is used as reference date/time, an absolute date/time is calculated by adding/subtracting a difference value at the forming date/time of the document based upon the relative year/month/day conversion database 115. This relative year/month/day conversion database 115 indicates a correspondence relationship between the relative character string which has been previously stored in the storage unit 105 and a difference value with respect to the reference date/time. The data which has been converted as the absolute date/time expression is stored into the absolute date/time storage unit 113 in correspondence with positional data within the document.
Next, the absolute display expression stored in the above-explained absolute date/time storage unit 113 is converted into a relative date/time expression based upon the above-described relative year/month/day conversion database 115 and the present date/time stored in the system date/time storage unit 111, and then, this converted relative date/time expression is stored into the relative date/time storage unit 114.
At this time, the correspondence relationship with respect to the positional data within the document is directly succeeded to be stored into the relative date/time storage unit 114.
Fig. 2A, Fig. 2B, and Fig. 2C are diagrams for showing contents of the relative year/month/day conversion database 115 employed in the storage unit 105 of the above-described information processing apparatus 100. Precisely, a relative year conversion table is shown in Fig. 2A, a relative month conversion table is indicated in Fig. 2B, and a relative day conversion table is represented in Fig. 2C.
In this relative year/month/day conversion database 115, relative date/time expression character strings corresponding to the difference date/time are stored, and are utilized when such a process operation for converting a relative date/time expression contained in the above-described document data into an absolute date/time expression is carried out, and also are utilized when such a process operation for converting an absolute date/time expression contained in the above-described document data into a relative date/time expression.
Subsequently, a description will now be made of a function of the document editing-purpose program 106 executed in the image processing apparatus 100 with employment of the above-described arrangement.
Fig. 3 is a flow chart for describing a relative date/time expression processing operation which is executed with respect to an electronic mail.
An input unit 101 is manipulated so as to designate an initiation function of the document editing-purpose program 106, so that the document editing-purpose program 106 stored in the storage unit 105 is read so as to be initiated (step 201).
When the document editing-purpose program 106 is initiated, document data is read, and then, a subject of a document is stored into a document subject storage unit 108; forming date/time of the document is stored into a document forming date/time storage unit 109; and also a main body of the document is stored into a document main body storage unit 110. Since the document editing-purpose program 106 is executed, the document data which are stored in both the document subject storage unit 108 and the document main body storage 110 are read out by either a predetermined character number or a preselected character string, and the date/time expression analyzing process operation is carried out with respect to the read data in order to judge as to whether or not such a character string indicative of date/time is contained in the read data based upon the fixed character string list (steps 202 and 203).
When it is so judged that the character string indicative of the date/time is not contained in the read document data, next document data is read, and then, the process operations defined in the above-described steps 202 and 203 are carried out with respect to this next document data.
To the contrary, when it is so judged that the character string indicative of the date/time is contained in the read document data, a check is made as to whether or not this character string corresponds to the relative date/time expression. While this character string is employed as a retrieve key, the relative date/time expression character strings of the relative year/month/day conversion data base 115 are retrieved. In the case that such a character string coincident with the above-described character string indicative of the date/time is present, it is so judged that this character string is equal to the relative date/time expression. To the contrary, when such a character string coincident with this character string indicative of the date/time is not present, it is so judged that this character string is not equal to the relative date/time expression (step 204).
When it is so judged that this character string is equal to the relative date/time expression, this relative date/time expression is converted into an absolute date/time expression in such a way that the document forming date/time data stored in the document forming date/time storage unit 109 is added to such a difference date/time which corresponds to the relative date/time expression character string of the relative year/month/day conversion database 115, which is made coincident with this character string (step 205). To the contrary, in the case that it is so judged that this character string is not equal to the relative date/time expression, this character string is processed based upon the cut-out logic of the fixed character string list so as to cut out a date/time portion thereof. Then, this cut-out date/time portion is stored as absolute date/time data into the absolute date/time storage unit 113 in correspondence with positional data of the character string.
A difference calculating process operation is carried out based upon the absolute date/time data stored in this absolute date/time storage unit 113 and the system date/time (step 206).
A relative date/time converting process operation is carried out by extracting such a relative date/time expression character string corresponding to a result of the above-described difference calculating process operation from the relative year/month/day conversion database 115 (step 207).
A relative day/time expression portion before being converted, which is contained in the subject of the document, is specified from the positional data corresponding to the relative date/time character string which has been converted by executing the above-described relative date/time converting process operation, and then, an emphasized character editing process operation such as a bold character and an italic character is carried out with respect to this character string (step 208).
The character string of the relative date/time expression after being converted is inserted into a position succeeding to the relative date/time expression character string before being converted, which has been edited by the above-described emphases character editing process operation. In this case, such a character string of the relative date/time expression after being converted may be displayed by inserting an expression capable of indicating a character string range such as symbols of ( ) and []
before/after this character string (step 209).
As previously explained, the relative date/time expression is appended on the basis of the present date/time with respect to the relative date/time expression and the absolute date/time expression while using the forming date/time contained in the subject of the document as the reference date/time.
It should be understood that the process operations defined in the respective steps shown in Fig. 3 may be executed by a program which has been stored into a computer-readable storage medium. This program is not always limited to be provided in the form of such a program stored in a storage medium, but may be provided in the form of such a program of a transfer medium which is provided via a network.
Fig. 4 illustratively shows an example in which, as previously explained, the date/time representation analysis is carried out with respect to the main body data of the document so as to display the relative date/time expression character string.
Fig. 5 indicates an example in which while the present invention is applied to a program directed to an electronic mail, when this electronic mail-purpose program is initiated, the above-described date/time expression analysis is carried out with respect to either a subject of a received electronic mail or a main body of this electronic mail, and relative date/time expression character strings are displayed in a subject list. In this example, since the relative date/time expression character string is inserted after the subject of the mail, a correspondence relationship between the relative date/time and the present date/time can be grasped at a first glance. Alternatively, as to an electronic mail, while a means for selecting such a process operation is provided and this process operation is executed by analyzing only a subject portion of a document and by converting an absolute date/time expression into a relative date/time expression of this analyzed subject portion, a time duration required for this analysis may be shortened.
In accordance with the present invention, the character string indicative of such a date/time which has already been entered is sensed, and then, the sensed such a character string indicative of the date/time is automatically converted into the relative date/time expression using the present date/time as the reference date/time, so that the correct relative relationship with respect to the present date/time can be obtained. Also, since the converted display is appended to the original sentence, recognitions of both the document forming person and the document reading person can be confirmed, and the erroneous recognitions made between both the document forming person and the document reading person can be reduced, so that the efficiency of the document forming operation can be improved.
It should be further understood by those skilled in the art that although the foregoing description has been made on embodiments of the invention, the invention is not limited thereto and various changes and modifications may be made without departing from the spirit of the invention and the scope of the appended claims.
When the document editing-purpose program 106 is initiated, document data is read, and then, a subject of a document is stored into a document subject storage unit 108; forming date/time of the document is stored into a document forming date/time storage unit 109; and also a main body of the document is stored into a document main body storage unit 110. Since the document editing-purpose program 106 is executed, the document data which are stored in both the document subject storage unit 108 and the document main body storage 110 are read out by either a predetermined character number or a preselected character string, and the date/time expression analyzing process operation is carried out with respect to the read data in order to judge as to whether or not such a character string indicative of date/time is contained in the read data based upon the fixed character string list (steps 202 and 203).
When it is so judged that the character string indicative of the date/time is not contained in the read document data, next document data is read, and then, the process operations defined in the above-described steps 202 and 203 are carried out with respect to this next document data.
To the contrary, when it is so judged that the character string indicative of the date/time is contained in the read document data, a check is made as to whether or not this character string corresponds to the relative date/time expression. While this character string is employed as a retrieve key, the relative date/time expression character strings of the relative year/month/day conversion data base 115 are retrieved. In the case that such a character string coincident with the above-described character string indicative of the date/time is present, it is so judged that this character string is equal to the relative date/time expression. To the contrary, when such a character string coincident with this character string indicative of the date/time is not present, it is so judged that this character string is not equal to the relative date/time expression (step 204).
When it is so judged that this character string is equal to the relative date/time expression, this relative date/time expression is converted into an absolute date/time expression in such a way that the document forming date/time data stored in the document forming date/time storage unit 109 is added to such a difference date/time which corresponds to the relative date/time expression character string of the relative year/month/day conversion database 115, which is made coincident with this character string (step 205). To the contrary, in the case that it is so judged that this character string is not equal to the relative date/time expression, this character string is processed based upon the cut-out logic of the fixed character string list so as to cut out a date/time portion thereof. Then, this cut-out date/time portion is stored as absolute date/time data into the absolute date/time storage unit 113 in correspondence with positional data of the character string.
A difference calculating process operation is carried out based upon the absolute date/time data stored in this absolute date/time storage unit 113 and the system date/time (step 206).
A relative date/time converting process operation is carried out by extracting such a relative date/time expression character string corresponding to a result of the above-described difference calculating process operation from the relative year/month/day conversion database 115 (step 207).
A relative day/time expression portion before being converted, which is contained in the subject of the document, is specified from the positional data corresponding to the relative date/time character string which has been converted by executing the above-described relative date/time converting process operation, and then, an emphasized character editing process operation such as a bold character and an italic character is carried out with respect to this character string (step 208).
The character string of the relative date/time expression after being converted is inserted into a position succeeding to the relative date/time expression character string before being converted, which has been edited by the above-described emphases character editing process operation. In this case, such a character string of the relative date/time expression after being converted may be displayed by inserting an expression capable of indicating a character string range such as symbols of ( ) and []
before/after this character string (step 209).
As previously explained, the relative date/time expression is appended on the basis of the present date/time with respect to the relative date/time expression and the absolute date/time expression while using the forming date/time contained in the subject of the document as the reference date/time.
It should be understood that the process operations defined in the respective steps shown in Fig. 3 may be executed by a program which has been stored into a computer-readable storage medium. This program is not always limited to be provided in the form of such a program stored in a storage medium, but may be provided in the form of such a program of a transfer medium which is provided via a network.
Fig. 4 illustratively shows an example in which, as previously explained, the date/time representation analysis is carried out with respect to the main body data of the document so as to display the relative date/time expression character string.
Fig. 5 indicates an example in which while the present invention is applied to a program directed to an electronic mail, when this electronic mail-purpose program is initiated, the above-described date/time expression analysis is carried out with respect to either a subject of a received electronic mail or a main body of this electronic mail, and relative date/time expression character strings are displayed in a subject list. In this example, since the relative date/time expression character string is inserted after the subject of the mail, a correspondence relationship between the relative date/time and the present date/time can be grasped at a first glance. Alternatively, as to an electronic mail, while a means for selecting such a process operation is provided and this process operation is executed by analyzing only a subject portion of a document and by converting an absolute date/time expression into a relative date/time expression of this analyzed subject portion, a time duration required for this analysis may be shortened.
In accordance with the present invention, the character string indicative of such a date/time which has already been entered is sensed, and then, the sensed such a character string indicative of the date/time is automatically converted into the relative date/time expression using the present date/time as the reference date/time, so that the correct relative relationship with respect to the present date/time can be obtained. Also, since the converted display is appended to the original sentence, recognitions of both the document forming person and the document reading person can be confirmed, and the erroneous recognitions made between both the document forming person and the document reading person can be reduced, so that the efficiency of the document forming operation can be improved.
It should be further understood by those skilled in the art that although the foregoing description has been made on embodiments of the invention, the invention is not limited thereto and various changes and modifications may be made without departing from the spirit of the invention and the scope of the appended claims.
