It is determined whether or not. In addition, a plurality of decomposed word groups are represented by an absolute date expression by determining whether the word “year” or “month” or “day” is arranged next to a predetermined number. It is determined whether or not it is a date word. The underlined date words 111 to 113 in FIG. 8 are date words extracted by the above-described method, and are temporarily stored as date word information 603. FIG. 9A is a conceptual diagram showing a storage state in which words underlined in FIG. 8 are temporarily stored in the RAM 6 as the date word information 603. It is determined whether the date word stored in the RAM 6 as the date word information 603 is a relative date expression registered in the relative date dictionary 703. If it is determined that the date is a relative date expression, step S203 is executed. If it is determined that the date is not a relative date expression, the absolute date expression conversion process is terminated. Step S202 is an example of a date expression determination step of the present invention.

  In step S203, after determining whether the date word stored in the RAM 6 as the date word information 603 in step S202 is a relative date expression registered in the relative date dictionary 703, the date word is represented by a relative date expression. Is determined, the date word represented by the relative date expression is converted into the absolute date expression based on the XML reception date information 6022. FIG. 9 shows a specific example in which the relative date representation is converted into the absolute date representation based on the XML reception date information 6022. FIG. 9A is a conceptual diagram showing the storage state of the date word information 603 before step S202 is executed, and FIG. 9B is a conceptual diagram showing the storage state of the date word information 603 after step S202 is executed. is there.

(Description of relative date expression conversion processing operation)
FIG. 10 is a flowchart for executing the relative date representation conversion processing according to the relative date representation conversion processing program 7013. First, in step S301, for each date word stored as date word information 603 shown in FIG. 9B, a date difference from the current date stored as current date information 601 is determined. FIG. 11 is a conceptual diagram showing a storage state in which the determined date difference is temporarily stored in the RAM 6 in association with the date word information 603. The date difference determined as shown in FIG. 11 is stored in the RAM 6 in association with each date word information stored as the date word information 603.

  In step S302, one date word among the date words stored in the RAM 6 as the date word information 603 is selected as a predetermined date word. In step S301 of the first embodiment, date words corresponding to ID numbers “1” to “3” associated with each date word are selected in order from the smallest number.

  In step S303, a relative date conversion table for converting the date word selected in step S302 into a relative date representation is determined. Based on the determined relative date conversion table, the date word selected in step S302 is converted into a relative date expression.

  In step S304, it is determined whether or not all date words stored in the date word information 603RAM 6 can be converted into relative date expressions. When it is determined whether or not all the date words stored in the RAM 6 as the date word information 603 can be converted into the relative date expression, the relative date expression conversion process is ended. If it is not determined whether or not all the date words stored in the RAM 6 as the date word information 603 can be converted into the relative date expression, step S302 is executed again.

(Description of table determination processing operation)
FIG. 12 is a flowchart for executing a table determination process according to the table determination program 7014. First, in step S401, it is determined whether the current date stored in the RAM 6 as the current date information 601 is a date representing the next day of the first day of the month. If the current date stored as the current date information 601 is a date representing the day after the first day of the month, step S402 is executed. If the current date stored in the RAM 6 as the current date information 601 is not date information representing the day after the first day of the month, step S404 is executed. For example, in the case of July, the date representing the day after the first day of the month is July 2.

  In step S402, it is determined whether a relative date expression corresponding to the date difference is stored in the first day of the month table shown in FIG. If a relative date expression corresponding to the date difference is stored, step S403 is executed. If it is determined that the relative date expression corresponding to the date difference is not stored, the table determination process is terminated.

  In step S403, the absolute date representation stored in the RAM 6 as the date word information 603 is converted into a relative date representation based on the first / next day table 7024 shown in FIG.

  In step S404, it is determined whether the current date stored in the RAM 6 as the current date information 601 is a date representing the first day of the month. If the current date stored in the RAM 6 as the current date information 601 is a date representing the first day of the month, step S405 is executed. If the current date stored in the RAM 6 as the current date information 601 is not a date representing the first day of the month, step S407 is executed. For example, in the case of July, the date representing the first day of the month is July 1st.

  In step S405, it is determined whether a relative date expression corresponding to the date difference is stored in the first month table shown in FIG. If a relative date expression corresponding to the date difference is stored, step S406 is executed. If it is determined that the relative date expression corresponding to the date difference is not stored, the table determination process is terminated.

  In step S406, the absolute date representation stored in the RAM 6 as the date word information 603 is converted into a relative date representation based on the month initial table 7023 shown in FIG.

  In step S407, it is determined whether the current date stored in the RAM 6 as the current date information 601 is a date representing the last day of the end of the month. If the current date stored in the RAM 6 as the current date information 601 is a date representing the last day of the end of the month, step S408 is executed. If the current date stored in the RAM 6 as the current date information 601 is not the date representing the last day of the end of the month, step S410 is executed. For example, in the case of June, the date representing the last day of the month is June 30. In the first embodiment, since “June 30” is stored in the RAM 6 as the current date information 601, step S <b> 408 is executed.

  In step S408, it is determined whether the relative date expression corresponding to the date difference is stored in the last day of the month table shown in FIG. If a relative date expression corresponding to the date difference is stored, step S409 is executed. If it is determined that the relative date expression corresponding to the date difference is not stored, the table determination process is terminated. In the first embodiment, as shown in FIG. 9B, “July 1” stored in the RAM 6 as the date word information 603 and “June” stored in the RAM 6 as the current date information 601 are displayed. The relative date expression corresponding to the date difference “1” from “30th” is stored as “next month 1st” in the last day table at the end of the month in FIG. Also, as shown in FIG. 9B, “June 29” stored in the RAM 6 as the date word information 603 and “June 30” stored in the RAM 6 as the current date information 603. The relative date expression corresponding to the date difference “−1” is stored as “Yesterday” in the last day table at the end of the month in FIG. Since the date difference between “July 8” shown in FIG. 9B and “June 30” stored as the current date information 601 is “8”, it is not the date difference shown in FIG. Therefore, “July 8” is not converted to a relative date representation.

  In step S409, the absolute date representation stored in the RAM 6 as the date word information 603 is converted into a relative date representation based on the last day of the month table 7021 shown in FIG. The date word “July 1” shown in FIG. 9B is converted to “Next month 1 day” based on the last day of the month table 7021. The date word “June 29” shown in FIG. 9B is converted to “Yesterday” based on the last day of the month table 7021.

  In step S410, it is determined whether the current date stored in the RAM 6 as the current date information 601 is a date representing the day before the last day of the end of the month. If the current date stored as the current date information 601 is a date representing the day before the last day of the end of the month, step S411 is executed. If the current date stored in the RAM 6 as the current date information 601 is not a date representing the day before the last day of the end of the month, step S413 is executed. For example, in the case of June, the date representing the day before the last day of the end of the month is June 29.

  In step S411, it is determined whether or not the relative date expression corresponding to the date difference is stored in the day before last day of the month table 7022 shown in FIG. If a relative date representation corresponding to the date difference is stored, step S412 is executed. If it is determined that the relative date expression corresponding to the date difference is not stored, the table determination process is terminated.

  In step S412, the absolute date representation stored in the RAM 6 as the date word information 603 is converted into a relative date representation based on the day-end last day table 7022 shown in FIG.

  In step S413, it is determined whether a relative date expression corresponding to the date difference is stored in the general date conversion table 7025 shown in FIG. If a relative date representation corresponding to the date difference is stored, step S414 is executed. If it is determined that the relative date expression corresponding to the date difference is not stored, the table determination process is terminated.

  In step S414, based on the general date conversion table 7025 shown in FIG. 3, the absolute date expression conversion stored in the RAM 6 as the date word information 603 is converted into a relative date expression.
