(System operation)
Hereinafter, each example of the operation of the related word display system according to the present exemplary embodiment will be described with reference to the drawings.

<First example>
FIG. 3 is a sequence diagram for explaining the first example. A first example will be described along the procedure of the sequence diagram of FIG. First, it is assumed that a keyword input screen is displayed on the user terminal 20 by a Web browser.

  Step 1) First, when a keyword is input (or selected) to the user terminal 20 by the user, the keyword is sent to the related word display control device 10. Hereinafter, this keyword is referred to as an input keyword. In the related word display control device 10, the keyword receiving unit 11 receives the input keyword and passes the input keyword to the related word information acquiring unit 12.

  Step 2) The related word information acquisition unit 12 accesses the related word information storage unit 32 in the search system 30, acquires a predetermined number of related words that are highly related to the input keyword, together with the value of the related degree, and stores the information. Store in unit 16. Here, “acquiring a predetermined number of highly related words” means, for example, acquiring a predetermined number of related words having a relevance level equal to or higher than a predetermined threshold in descending order of relevance. It is. The predetermined number is, for example, 8.

  The method for extracting a predetermined number of related words is not limited to the above method. For example, a search number (number of times used for searching in a predetermined period) is searched for each related word hit in the related word information storage unit 32. It is also possible to obtain from the log information storage unit 31 and extract a predetermined number of high-order items with a large number of searches.

  Step 3) The related word information acquisition unit 12 further retrieves the number of searches for the input keyword and the related word acquired in Step 2 from the search log information storage unit 31 in the search system 30 (the number of times used for the search in a predetermined period). ) And stored in the information storage unit 16, and checks whether each of the input keyword and the related word acquired in step 2 is registered as a sudden rise word in the sudden rise word storage unit 33. In this case, information indicating that the corresponding word is a rapidly increasing word is stored in the information storage unit 16. If the number of searches has already been acquired in step 2, it is not necessary to acquire the number of searches in step 3.

  Step 4) The display control information creation unit 13 creates display control information using the information acquired by the related word information acquisition unit 12 in steps 2 and 3.

  Step 5) The display control information transmitting unit 14 transmits the display control information created by the display control information creating unit 13 in Step 4 to the user terminal 20.

  Step 6) The user terminal 20 performs screen display using the display control information received from the related word display control device 10. As described above, the display control information may be a screen image itself or a display command. Alternatively, an image and a display command may be mixed. In the display control information, for example, the display position, display size, color, display method (for example, blinking), and display object for each display object (object) such as characters and graphics are selected (click or mouse cursor on). Information such as the processing contents in case of a failure is included.

  FIG. 4 shows a screen display example displayed on the user terminal 20. As shown in FIG. 4, the user terminal 20 displays a screen in which related words are radially arranged around the input keyword (“cloud” in the example of FIG. 4). The example of FIG. 4 shows a case where eight related words are acquired, and the related words are arranged radially at equal angular intervals on a circle centered on the input keyword.

  The distance between the input keyword and each related word may be uniform, or the distance may be changed according to a predetermined condition. For example, the higher the degree of association, the shorter (or longer) the distance between the input keyword and the related word. Focusing on the number of related word searches, the distance from the input keyword can be shortened (or lengthened) as the related word has a larger number of searches. Alternatively, the distance may be determined in consideration of both the degree of association and the number of searches.

  As shown in FIG. 4, a circle (circle) is displayed over the related words. The size of this circle can be changed according to a predetermined condition. For example, the higher the relevance, the larger the circle. In addition, paying attention to the number of searches for related words, the related words with a larger number of searches may be made larger. Alternatively, the size of ○ may be determined in consideration of both the degree of association and the number of searches. Further, as the size of ◯, the number of steps (for example, 3 steps) and a reference size may be determined in advance, and the standard may be 100%, the slightly larger 110%, and the slightly smaller 90%.

  The method of reflecting the degree of association and the number of searches on the screen display is not limited to the distance from the input keyword and the size of ○ as described above. For example, the character color of the related word or the circle of ○ The fill color may be changed according to the degree of association or the number of searches, or the size of the character may be changed according to the degree of association or the number of searches. In short, at least one of the size, color, and distance between the display objects (characters, figures, backgrounds, etc.) on the screen displayed on the user terminal 20 is the related word acquired by the related word information acquisition unit 12. The information is determined according to the degree of association and / or the number of searches included in the word information, and the determined information is reflected in the display control information, and the screen is displayed by the display control information reflecting these information.

  Further, for example, words (input keywords, related words) registered as a rapidly increasing word are displayed in a color (for example, red) different from that of a word that is not a rapidly increasing word.

  The screen display including the input keyword, the related word, and the like is not limited to the above example. For example, the background color or shape may be changed, or the characters may be blinked.

  Step 7) Returning to FIG. 3, the user selects (clicks in this example) a specific related word on the screen displayed in Step 6.

  Step 8) A search request using the input keyword and the related word selected in Step 7 as a query is sent from the user terminal 20 to the related word display control device 10.

  Steps 9, 10, and 11) The search execution unit 15 of the related word display control device 10 performs a search based on the search request of Step 8, and the search result is transmitted to the user via the search execution unit 15 of the related word display control device 10. The user terminal 20 displays the search result.

  In step 8 above, when the related word is selected, the function of sending a search request based on the input keyword and the related word is the same as the display control information received in step 5 (and the Web browser or the like that the user terminal 20 has in advance). Function).

  In the above example, in steps 8 to 10, the search execution unit 15 of the related word display control device 10 executes a search. It is also possible to perform a search directly from the search system 30 to the user terminal 20 and receive the search results directly from the search system 30.

  In the above example, when a related word is selected on the user terminal 20, the search is performed using the input keyword and the related word, but the search may be performed using only the related word.

<Second example>
Next, a second example will be described. The processing contents in the second example are basically the same as those in the first example, but the display contents are different. In the following, differences from the first example will be mainly described.

  FIG. 5 is a diagram showing a screen display example displayed on the user terminal 20 in step 6 of FIG. 3 in the second example. As shown in FIG. 5, in the second example, when the input keyword is a company name, competitor information (name of the competitor in the example of FIG. 5) is displayed.

  In the second example, for example, the search system 30 or the related word display control device 10 includes a competitor information storage unit (database) that stores competitor information corresponding to a company name for each company name. In step 3 or the like, the information acquisition unit 12 searches the competitor information storage unit using the input keyword, and acquires competitor information when a hit is found. Then, the display control information creation unit 13 creates display control information including competitor information.

  When a specific competitor is selected (clicked) on the user terminal 20 on which the screen shown in FIG. 5 is displayed, the name of the competitor is the related word display control device 10 as an input keyword in step 1 of FIG. After the processing described in the first example (and the second example), the screen shown in FIG. 4 or FIG. 5 in which the competitor name is placed at the center of the radiation is displayed.

  Instead of the above processing, when a specific competitor is selected (clicked) on the user terminal 20 on which the screen shown in FIG. 5 is displayed, the search system 30 sends a search request with the name of the competitor as a query. You may make it carry out with respect to.

  Further, instead of displaying competitor information as shown in FIG. 5, when the input keyword is a company name, the competitor information is extracted from the competitor information storage unit, and the name of the extracted competitor is input keyword. 4 may be used to display the screen of FIG. 4 by performing the processing of the first example. When there are a plurality of extracted competitors, for example, the first example process is performed for each competitor to display windows having the screen of FIG. 4 as many as the number of competitors.

<Third example>
Next, a third example will be described. The processing contents in the third example are basically the same as those in the first example, but the display contents are different. In the following, differences from the first example will be mainly described.

  FIG. 6 is a diagram for explaining the third example. As shown in FIG. 6, in the third example, first, the related words are displayed in a radial manner centering on the input keyword by the processing described in the first example ((a) of FIG. 6). Here, when the user selects a specific related word (selection method different from step 7 in the first example, for example, the mouse cursor is turned on), the selected related word is used as an input keyword from step 1 in the first example. As shown in FIG. 6B, a radial related word display centered on the selected related word is displayed on the user terminal 20. Also in the third example, competitor information may be displayed as in the second example.

<Fourth example>
Next, a fourth example will be described. The processing contents in the fourth example are basically the same as those in the first example, but the display contents are different. In the following, differences from the first example will be mainly described.

  In the first example, there is one input keyword, but there may be a plurality of input keywords. In this case, as shown in FIG. 7, related words centered on the first described input keyword are displayed radially, and each of the input keywords other than the first described input keyword among the plurality of input keywords. Are displayed as related words in a radial pattern together with other related words. Here, the “input keyword described first” is AAA when a plurality of input keywords are “AAA BBB”, for example.

  Further, regarding the related word that is the input keyword, the processing for the input keyword in the first example is performed, and the related words related to the related word are displayed radially. That is, they are displayed radially and hierarchically. In the example of FIG. 7, there are two input keywords, the first input keyword is the keyword XXX, and the second input keyword is the keyword YYY.

  In the fourth example, for example, in Steps 1 to 4 in FIG. 3, the related word, the degree of association, and the rapid increase information for each input keyword in the plurality of input keywords are acquired, and using these acquired information Display control information that enables the screen display of FIG. 7 is created. Further, the fourth example may be combined with the second and third examples.

  The present invention is not limited to the above-described embodiments, and various modifications and applications are possible within the scope of the claims.
