(Example of search result display)
A display example of the search result performed by the e-mail transmitting/receiving device 10 will be described with reference to FIGS. 4 and 5. FIG. FIG. 4 is a first diagram showing an example of a display form of search results. FIG. 5 is a second diagram showing an example of the display form of search results.

An operator who sends an e-mail from the e-mail transmitting/receiving device 10 creates the title and body of the e-mail to be sent and sets the destination of the e-mail, and then instructs the e-mail to be sent. Here, the method of setting the destination of the mail will be explained.

The operator selects a menu for setting a mail destination from a menu screen (not shown) displayed on the display device 16 . When the menu is selected, the display device 16 displays a destination search screen 40 shown in FIG.

The destination search screen 40 includes a search information input field 41 , a search result display space 42 , and a fixed destination display field 43 .

The search information input field 41 is a field in which information (character strings) input by the user is displayed. The user uses the operation device 17 to enter the name, attributes, or e-mail address of the person to whom the e-mail is to be sent. The name can be entered in hiragana, kanji, or romaji. Here, the case where the name of the person to whom the e-mail is to be sent is entered in hiragana notation will be described.

The search result display space 42 is a space in which the results of searching the information database D by the search execution unit 22 based on the information input in the search information input field 41 are displayed.

The fixed destination display column 43 is a column in which information selected by the search result selection unit 24 from among the information displayed in the search result display space 42 is displayed.

The destination search screen 40 shown in FIG. 4 is an example in which the search result for the character string “HARAMIKA” input by the operator is displayed in the search result display space 42 . Specifically, a search result 421 and a search result 422 are displayed in the search result display space 42 .

The search result 421 is a character string that has the highest degree of matching with the character string input in the search information input field 41 . The search result 422 is the character string with the second highest degree of matching. Note that the search result display space 42 may display the character strings of the third candidate and below.

In the example of FIG. 4, since hiragana characters are entered on the destination search screen 40, the search execution unit 22 calculates the degree of matching with the character strings written in hiragana characters from the information database D. FIG. Therefore, the search execution unit 22 searches for a character string written in hiragana that has the highest degree of matching. Therefore, originally, the search results should be displayed in hiragana notation in the search result display space 42, but for the reason that comparison with other candidates can be easily performed, the example in FIG. displaying a string. Of course, a character string written in hiragana may also be displayed.

The degree of matching between two character strings represents the closeness of the distance between the character string entered in the search information input field 41 and the character string registered in the information database D. FIG. In the example of this embodiment, the closer the distance between the information input in the search information input field 41 and the information registered in the information database D, the higher the degree of matching.

The distance between the character string entered in the search information input field 41 and the character string registered in the information database D is calculated according to a known method. For example, the Levenshtein distance or the Jaro-winkler distance between the character string "Haramika" entered in the search information input field 41 and the character string registered in the information database D Distance), etc. are calculated.

The Levenshtein distance is the number of editing operations required when one character string is edited and converted to the other character string. It is represented.

The Jaro-Winkler distance is the distance between two character strings calculated from the number of matching characters between one character string and the other character string and the necessity of replacement.

By calculating the distance between such character strings, a character string including at least part of the character string input in the search information input field 41 is searched. The search results are sorted in descending order of degree of matching, that is, in descending order of distance.

Next, display forms of the search results 421 and 422 will be described. A search result 421 and a search result 422 indicate a name including a character string highly matched with the character string input in the search information input field 41 and the affiliation of the person having the name. In the example of FIG. 4, the search result 421 is the name with the highest degree of matching, and the search result 422 is the name with the second highest degree of matching.

In particular, in the search result 421, the character string entered in the search information input field 41 completely matches the search result. In this way, when the character string input in the search information input field 41 completely matches the search result, the search result display unit 23 of the e-mail transmitting/receiving device 10 changes the font (form) of the search result to bold. to display.

A search result 422 is a search result in which only the character strings "haramina" and "harami" which are the character strings input in the search information input field 41 match. The affiliation of the person corresponding to the search result 422 has a different group name from the affiliation of the person of the search result 421 with the highest degree of matching. In such a case, the search result display unit 23 of the e-mail transmitting/receiving device 10 displays the identification symbol 45 at the end of the search result 422 . The identification symbol 45 is assigned to a search result that differs from the person corresponding to the first candidate search result in a department name or group name. By assigning the identification symbol 45, the operator of the e-mail transmitting/receiving device 10 is made to recognize that the affiliation of the person of the first candidate and the affiliation of the candidate person to which the identification symbol 45 is assigned are different. can be done. Furthermore, the search result 422 is displayed in a thinner font (form) than the search result 421 because the character string input in the search information input field 41 does not completely match the search result.

In this way, the e-mail transmitting/receiving device 10 can display the search result of the person to whom the e-mail is to be sent, in the order and form according to the degree of matching with the name or attribute input in the search information input field 41. can.

The destination search screen 50 in FIG. 5 shows another example in which search results 421 and 422 for the character string “HARAMIKA” input by the operator are displayed in the search result display space 42 .

In FIG. 5, a retrieval result 422 is provided with an identification symbol 46 having a form different from the identification symbol 45 described above. The identification symbol 46 is assigned to search results in which the company name is different from the person corresponding to the search result of the first candidate. By assigning the identification symbol 46, the operator of the e-mail transmitting/receiving device 10 recognizes that the company name of the first candidate person is different from the company name of the candidate person to whom the identification symbol 46 is attached. can be made As a result, it is possible to prevent a person from a different company from being mistakenly selected for sending an e-mail.

(How to select search results)
Next, with reference to FIG. 6, a method of selecting an e-mail destination from a plurality of search results will be described. FIG. 6 is a diagram explaining a method of selecting one of a plurality of search results.

A method of selecting search result 421 when search results 421 and 422 are displayed on destination search screen 40 as shown in FIG. 6 will be described.

When the operator moves the cursor 47 on the destination search screen 40 and the cursor 47 approaches or overlaps (rolls over) the search result 421, the destination search screen 60 is displayed by the action of the search result selection unit 24. As shown, a selection marker 48 containing search results 421 is displayed. Also, although not shown, when the cursor 47 approaches or overlaps the search result 422, a selection marker 48 including the search result 422 is displayed. Instead of displaying the selection marker 48, the color of the rolled over object (search result) may be changed.

In the state of the destination search screen 60, that is, when the cursor 47 rolls over the search result 421, when a confirmation operation (mouse ON, keyboard enter key press, etc.) is performed, the rolled over search result is selected. , the name in the search result is displayed in the fixed destination display field 43 as shown in the destination search screen 70 .

Note that the selected name may be displayed in the transmission column of the e-mail application screen instead of the fixed destination display column 43 .

(Flow of processing performed by the e-mail transmitting/receiving device)
The flow of processing performed by the e-mail transmitting/receiving device 10 will be described with reference to FIG. FIG. 7 is a flowchart showing an example of the flow of e-mail transmission processing performed by the e-mail transmission/reception device according to the embodiment. It is assumed that the text of the e-mail has already been created.

The input information acquisition unit 21 acquires the name entered in the search information entry field 41 (step S11).

The search execution unit 22 performs a search process for searching information including at least part of the name acquired in step S11 from the information database D (step S12). A detailed flow of the search processing will be described later (see FIG. 8).

The search result display unit 23 causes the display control unit 25 to display the search results obtained by the search process in step S12 in the search result display space 42 in the order and form according to the degree of matching with the name acquired in step S11. (Step S13).

The search result selection unit 24 selects one search result from the search results displayed by the search result display unit 23 . Then, it causes the display control unit 25 to display the selected search result in the fixed destination display field 43 (step S24).

The communication control unit 27 transmits the e-mail to the destination selected in step S24 (step S25). After that, the processing of FIG. 7 ends.

Next, the flow of search processing performed by the e-mail transmission/reception device 10 will be described with reference to FIG. FIG. 8 is a flowchart showing an example of the flow of search processing.

Specifically, it specifies whether the type of notation of the name input in the search information input field 41 is hiragana notation, kanji notation, or romaji notation.

Next, in the information database D shown in FIG. 3, the search execution unit 22 calculates the matching degree of information for the field (vertical axis direction) corresponding to the notation of the name specified in step S21 (step S22). The calculated degree of matching is stored, for example, in the RAM 113 together with the ID 31 corresponding to the name for which the degree of matching is obtained.

The search execution unit 22 determines whether all the information in the field has been checked (step S23). If it is determined that all the information in the field has been collated (step S23: Yes), the process proceeds to step S24. On the other hand, if it is not determined that all the information in the field has been checked (step S23: No), the process returns to step S22.

When it is determined in step S23 that all the information in the field has been matched, the search execution unit 22 sorts the IDs 31 stored in the RAM 113 in descending order of degree of matching (step S24). After that, the process proceeds to step S13 in FIG. It should be noted that ID31 sorted at the top by the process of step S24 is the most probable search result.

As described above, the e-mail transmitting/receiving device 10 (information retrieving device) according to the first embodiment includes an information database D in which at least the name (name of information) of the person to whom the e-mail is sent is registered, and the search target an input information acquisition unit 21 (acquisition unit) that acquires the name of the person, and a search execution unit 22 that searches the information database D for a name that includes at least part of the name of the person acquired by the input information acquisition unit 21 and a search result display unit 23 (display unit) that displays the search results by the search execution unit 22 in an order and in a form according to the degree of matching with the name of the person acquired by the input information acquisition unit 21, and a search result display unit and a search result selection unit 24 (selection unit) for selecting one search result from the search results displayed by 23 . Therefore, even if there are similar names, it is possible to select the destination of the e-mail that the user desires without making a mistake.

In addition, in the e-mail transmitting/receiving device 10 (information retrieval device) of the first embodiment, the search result display unit 23 (display unit) displays the search result by the search execution unit 22 as the search result and the input information acquisition unit 21 is displayed in descending order of degree of matching with the name of the person acquired by .
