DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An information terminal device with a communication search function and an information terminal processing method according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a system block diagram illustrating a configuration of an information terminal device according to an embodiment of the present invention.

In FIG. 1, reference numeral 1-1 denotes a CPU as an operation control processing unit of the system; 1-2, a display unit for outputting schedule data, a search keyword, and search data;
Reference numeral -3 denotes an input unit for inputting operation information of the present system, which corresponds to a pointing device such as a KEY, a mouse, and a pen.

Reference numeral 1-6 denotes a memory unit, that is, a RAM / ROM for storing information and programs of the present system, which includes a search keyword memory 1-6-1 and an automatic external search mode flag 1-6-2 described later. , Schedule data 1-6-3, time element database 1-6-4 as an internal database for search, semantic element database 1-6-5, and other databases 1-6 such as address book
6, external search specification information 1-6-7 included in each database, and automatic external search specification table 1-6
8, representative external database information 1-6-9, and a program section 1-6-10 for overall control of the system.

These RAMs / ROMs can be provided in a magnetic recording unit, an IC card, or another information storage medium as needed, and can be used.

A communication connection section 1-4 is connected to a public telephone line or the like, and is connected to an external database 1-5. The external database 1-5 indicates a commercial database for each purpose, a database at an Internet destination, a search service database for searching an Internet homepage included therein, and the like.

FIGS. 2 and 3 show flowcharts when the present system actually operates. This flow control is prepared by the control program 1-6-10 in FIG.

FIG. 6 shows an example of display data when the present invention is executed. In FIG. 6, the display unit is provided with a schedule display area, an internal database search result display area, an external database display area, and a search keyword display area, each of which is provided separately or is superimposed on a window when data is displayed. It is expressed while doing it.

Here, the enlarged schedule display area is the upper schedule in FIG.

In the schedule display for this explanation, the calendar for October 1998 is
A memo saying that the date of physical education is entered on the 10th of the month, and a memo for traveling to Nara is entered on October 14th to 15th. It is assumed that weekly stock confirmation is set on Thursday.

Here, in the search targeted by the present invention, a selection instruction is given on a memo of travel to Nara using a pointing device or the like, or a pointing device or the like is added on a memo of physical education or on a date of October 10. When a search instruction is given by specifying the target coordinates on the display by some method, such as when a search instruction is given by pressing a search key (not shown), etc., the search information is searched as the extraction keyword The processing is executed according to the flowcharts of FIGS. 1 and 3 to display the later-described search keywords corresponding to the extracted keywords in the display screen of FIG. Alternatively, data from an external database is displayed in a target display area.

Here, the point of the present invention is that the internal database is searched according to the above search instruction, and the external database is automatically searched as necessary.

Now, the operation will be described. In FIG. 2, in step S1 (hereinafter simply referred to as S1), keywords are extracted from the specific area and the vicinity of the specific area. Explaining with a calendar display, the coordinates between the 14th and 15th of October (the P1 position indicated by a black dot) are not on the extracted keyword.
However, on October 14 and October 15, a note to travel to Nara was attached, and the note to travel to Nara was P
It means that it is extracted as one extracted keyword. The specific area indicates on the memo coordinates written as a trip to Nara, and can be directly specified.

In the P1 coordinates, the keyword of the third week of October 1998 is hidden, and the keywords of Tuesday and Wednesday are also hidden.

S2 is a part for determining whether the extracted keyword is a time element or a semantic element. If the first candidate of the extracted keyword of P1 is a trip to Nara, it is determined to be a semantic element. If there is, it is determined to be a time element and the search of each element database is started.

That is, if it is determined in S2 that the element is a time element, the processing proceeds to S3. If it is determined that the element is a semantic element, the processing proceeds to S14.

Here, the time element database and the semantic element database will be briefly described first, as shown in 1-6-4 and 1-6-5 in FIG.
Storage unit in the memory of AM / ROM or equivalent (internal /
In the external storage device, search keywords and their correspondence are provided in pairs as shown in FIG.

The search keyword means a unified word indicated by the meaning of the extracted keyword, which is a natural word, and this relation is described in a dictionary section in the memory, which is not separately described. This is what is replaced and extracted.

Various techniques for data retrieval already exist as a method of replacing a natural language keyword with a unified word keyword.

In response to the search keyword, if there is data that can be directly displayed and output, the data is stored as display data. If it is necessary to proceed to another internal database search, the other internal database search conditions are specified. If you wish to access external information, specify the external database information there.

The display data here is, for example, October 1
In the case of 0th day, it is information that can be specified on that day, such as information on the day of physical education, and the other internal database search condition is a search for another schedule if it is a time element related to another schedule Specify the conditions and refer to the actual display data, or refer to the external database information. For example, on the day of physical education on October 10, connect to an Internet homepage similar to that of access point xxxx for information. To specify the communication destination, such as to obtain

The semantic element database has the same idea, and is a database in which a search keyword is a semantic keyword. For example, if the extracted keyword is travel to Nara, Nara or travel is extracted as a search keyword as a search keyword, and the correspondence is prepared in the semantic element database.

On October 10 and the day of physical education, it is not necessary to assign the same processing data to both element databases, and display data or external database information corresponding to the processing data on one side and the other on the other side. It is also possible to instruct a process to access the element database as a correspondence.

This processing can be performed by switching to another element database in S4 or S15 in the flowchart of FIG.

The reason why the keyword is divided into the time element and the semantic element is that, when October 10 in FIG. 6 is designated, the search keyword as the semantic element is only the day of physical education, but in the case of the time element, it is Friday or Friday. This is because other conditions, such as the second week, are included, and it is necessary to search for them.

For reference, it is possible to extract the semantic element of the physical education day by specifying the memo display on the physical education day.
For the time element extraction on October 10, the area indicated by the broken line on October 10 is specified. In the area other than the memo display on the day of physical education, it is determined that the time element is to be extracted, and the extraction keyword is determined.

The retrieval of the time element database in S3 of FIG. 2 includes a plurality of conditions. For this purpose, the step S3 operates as shown in the flowchart of FIG.

In FIG. 3, the extracted keyword of the time element to be extracted is designated as the designated time in S20, and the retrieval keyword is set as YYYY. MM. DD. A search is performed as TT, and in S21, a search is performed to determine whether or not there is data determined until the designated time.
If no, enter the process of S23. (The processing of J2 will be described later).

In S23, since there is no data up to the time designation, the search keyword is extracted as YYYY. MM. As DD, the time element database is searched in S24, and if there is data in S25, the process proceeds to J2, and if not, the process proceeds to S26.

Similarly, the designated days are S26, S27, S2
At 8, the designated week is S29, S30, S31, and the designated month is S
32, S33, S34, designated seasons are S35, S36, S
37, the designated year is executed in S38, S39 and S40. If there is still no target, the process enters J1.

If the extracted keyword of the time element to be extracted first has information up to the month and there is no date and time information, the process is passed from S20 to S31 because there is no target. As YYYY. The MM is extracted, and the time element database is searched in S33.

That is, when October 1998 is designated in FIG. 6, 1998.10 is searched in the time element database as a designated keyword. in this way,
In the time element, the database is searched while the keyword is changed in the direction of expansion, and the correspondence of the database is known.

If the display data is extracted at this time in FIG. 4, the process proceeds from S4 to S7 in FIG. 2, the data is displayed, and the next candidate request is confirmed in S8.

If an external database is extracted in FIG. 4, the external database is searched in S5 of FIG. 2, and if the display data is extracted as a result, the data is displayed in S7 and the data is displayed in S8. Next, a next request is made, and if there is no display data extracted in S6, the procedure for the next request is entered in S8.

When the meaning element is designated in FIG.
To enter the processing of S14. In addition, if there is no data in FIG. 4 and J1 is reached, the process proceeds to S9 in FIG.

S9 and subsequent steps will be described later. If it is determined in S2 that the data is a semantic element, the data is extracted by searching the semantic element database of FIG. 4 in S14.
In the case of a trip to Nara on October 14 and 15, an extracted keyword is extracted as a trip to Nara, and this is analyzed as a natural language as an extracted keyword in a dictionary or the like, and a search keyword such as Nara or a trip is extracted. .

As described above, the conversion from the extracted (natural language) keyword to the search (unified) keyword is a known technique, and although not described in detail here, a semantic element database is used for the search keyword of Nara or travel. Is searched, and display data registered in the corresponding column of FIG. 4, an external database or a time element database, or a process without data is executed.

Thus, when the display data is extracted in S15 of FIG. 2, the data is displayed in S7, when the external database instruction is extracted in S15, the external database is searched in S5, and when the time element is specified in S15. Searches the time element database in S3, and if there is no target data, the process proceeds to S9.

Next, the processing after entering S9 from S4 and S15 will be described.
An automatic external search mode flag is provided at -6-2 to determine whether the external search can be automatically performed when the external search of the present invention of the system is not instructed in the time element database or the meaning element database. The mode can be designated. When the mode is designated, the automatic external search mode flag is set to 1, and when the mode is canceled, the flag is set to 0.

Thus, if the automatic external search mode is designated in S9 of FIG. 2, the process proceeds to S10, and if not, the process proceeds to S16.

Then, if any search database can be specified in S10, an external database search is performed in S5. If no search database can be specified, the process proceeds to S11.

In the determination in S10, the search external database is determined by comparing the automatic external search designation table of FIG. 5 with the extracted keywords and finding the presence of the search keywords. Here, the search external database is provided as an object whose connection information to hundreds of provided services (vendors) in Japan and overseas is considered to be optimal for each keyword.
For example, if it is related to a row, if a database provided by an event company is set, it is automatically connected to the database.

In general, even for a keyword for which no object exists, an object can be obtained by connecting to a homepage search service on the Internet.

However, in the case of a code which does not become a search keyword, for example, a simple numerical value, the target database cannot be specified, so that it becomes necessary to find the next keyword near the display in S11.

If another keyword exists nearby, S2
Is entered in the next search. If it is difficult to extract another keyword, the user is prompted to enter another keyword in S12.
At 13, it is also possible to enter another keyword from a key input or the like.

If no external search mode is specified in S9, the operator is asked in S16 whether or not the external search is permitted. If an external search is to be performed, an external database is specified in S18. To S5.

If the external search is not performed in S16, S17
Then, the next search is confirmed. If the next search is not performed, the process ends. If the next search is performed, the process proceeds to S11.

Since the external database search in S5 is a well-known technique, details will not be described again. As a result, if there is display data, it is determined in S6. If the data is not displayed in S7, the process proceeds to S8. To confirm the next request.

As described above, the search keywords, the internal database search result display, and the external database search result display are displayed in each area of FIG. 6 as described above. Data can be viewed.

The above operation is the overall operation of the present invention. Generally, the data in the internal database in FIG. 4 is provided with corresponding data corresponding to keywords expected from the design time. Can be added as needed.

Similarly, the automatic external search designation table shown in FIG. 5 can be provided from the beginning, but can be added by the user as needed.

In each of the external database information shown in FIGS. 4 and 5, it is assumed that connection target telephone numbers, auto login information, and the like are stored.

As a method of designating an external database in S18 of FIG. 2, it is also possible to output various external database connection information in a list display format and to select a specific one of them.

The external database connection information is stored in the representative external database information (1-6 in FIG. 1).
-9).

The information stores the connection destination telephone number and the auto-login information of the general database, and details are not specified again.

By configuring the system as described above, it is possible to automatically perform the internal search and the external search from the keyword extraction of the first aspect. Also allows external search,
An external search can be performed using another keyword again.

Further, since the extraction and display of the search keyword (claim 4) can be performed by ranking, it is possible to provide an easy-to-use schedule follow-up system. In addition, the present invention is not limited to only the embodiments described above and shown in the drawings, and it goes without saying that the present invention can be appropriately modified and implemented without departing from the scope of the invention.
