Description

  The present invention relates to a system, a method, and a program for providing a suggestion keyword used as a search keyword in a search system, for example.

  In recent years, with the development of the Internet, a search service developed in the Internet environment, such as Google search (Non-Patent Document 1), has been widely used.

  According to this type of search service, when a user inputs a keyword, not only related information is searched from all over the world, but also a suggestion keyword that is a term highly related to the input keyword is provided. .

  Furthermore, using this type of search service, the user can also search using an AND condition of the keyword entered by the user and the suggestion keyword. As a result, the user can efficiently obtain desired information with fewer operations.

  Such a suggestion function for outputting a suggestion keyword is introduced not only in the search service as described above but also in online shops and video sites.

  According to the suggestion function, a suggestion keyword is selected based on a search volume, which is the number of times the keyword is searched for by the user, a user's residence, a language used, and a keyword searched immediately before.

https://www.google.com/ <Search August 3, 2018>

  As described above, a search service deployed in the Internet environment has a suggestion function, so that the search efficiency can be improved. However, on the other hand, there is a problem that the search function deployed in the Internet environment may cause the suggestion function to be contaminated.

  Suggestion contamination means that the suggestion function outputs a large amount of negative keywords. For example, when a certain company name is input as a search keyword, it indicates a state in which negative suggestion keywords such as “black”, “copyright infringement”, and “scam” are frequently displayed.

  Such a state occurs, for example, when a certain keyword is input in a large amount into the search service under an AND condition with a negative keyword.

  This can be done intentionally by a malicious user. Moreover, even if there is no malicious intent, it may occur when the flames on the Internet or bad rumors are spread. For example, in order to confirm the truth when a flame or bad rumors are circulated on the Internet, a large number of unspecified users can identify specific people or organizations that are subject to flames or rumors. This is because the negative keyword is input to the search system at the same time.

  When the search service is affected by such suggestion contamination, the suggestion function displays a suggestion keyword that is less relevant to what the user wants, and the reliability is lowered.

  The present invention has been made in view of such circumstances, and an object thereof is to provide a suggestion keyword providing system, method, and program capable of providing a suggestion keyword without being contaminated with suggestion.

  Embodiments of the present invention will be described below with reference to the drawings.

(First embodiment)
FIG. 1 is a block diagram illustrating a configuration example of a suggestion keyword providing system to which the suggestion keyword providing method according to the first embodiment is applied.

  A suggest keyword providing system (hereinafter abbreviated as “providing system”) 10 includes a CPU 12, a recording medium reading unit 14, a display 15, a key input unit 16, a communication unit 17, a storage device 18, and A memory 20 is provided.

  The key input unit 16 is a part that receives an input of a keyword from the user, such as a keyboard and a mouse.

  The CPU 12 is a computer, and includes a user authentication program 21, a log information storage program 22, a suggestion keyword extraction program (hereinafter, abbreviated as “extraction program”) 23, and a suggestion keyword providing program (hereinafter, referred to as “memory” 20). , Abbreviated as “providing program”) 24, the internal operation of the suggestion keyword providing system 10 is controlled.

  The user authentication program 21, log information storage program 22, extraction program 23, and provision program 24 may be stored in the memory 20 in advance, or from an external recording medium 13 such as a memory card via the recording medium reading unit 14. May be read and stored in the memory 20.

  The user authentication program 21, log information storage program 22, extraction program 23, and provision program 24 cannot be rewritten by input from the key input unit 16 by the user.

  In addition to such information that cannot be rewritten by the user, the memory 20 is an area where information corresponding to the input made by the key input unit 16 is sequentially input as an area for storing data that can be rewritten by the user. A writable data area 25 is secured.

  The communication unit 17 is connected to a communication network 30 such as the Internet, for example, and communicates with the search system 40 that provides a search service via the communication network 30. The providing system 10 may be integrated with the search system 40.

  The storage device 18 includes, for example, an SSD (Solid State Drive), an HDD (Hard Disk Drive), and the like, and stores user information and log information as will be described later.

  In the providing system 10 configured as described above, the CPU 12 controls the operation of each unit according to the instructions described in the user authentication program 21, the log information storage program 22, the extraction program 23, and the providing program 24, and the software and hardware Cooperate with each other to operate as described below, thereby providing a suggestion keyword based on the keyword input from the key input unit 16 by the user.

  Next, a detailed configuration of the providing system 10 will be described.

  Providing system 10 limits users to prevent suggestion features from being polluted. That is, the providing system 10 does not develop services in an open environment. For example, in the same organization (for example, the same company, government office, etc.), in the same office (for example, the same call center, etc.), in the same group ( Deploy services in a closed environment such as the same organization) or individuals.

  Therefore, the user authentication program 21 performs user authentication using a user ID, a password, etc., and confirms that the user is an authorized user.

  An example of user authentication performed by the user authentication program 21 will be described with reference to FIG.

  FIG. 2 is a data structure diagram illustrating an example of the user information table 50.

  As an example, the user information table 50 includes items such as a user name 50a that is a user name, a user ID 50b that is a user ID number, a user password 50c, and a group 50d to which the user belongs. These items are examples, and the user information table 50 may include more items or fewer items as necessary.

  The storage device 18 stores a user information table 50 illustrated in FIG.

  When using the providing system 10, the user needs to log in to the providing system 10. Login is performed by inputting the user name 50a or the user ID 50b and the password 50c from the key input unit 16. When the user inputs these information from the key input unit 16, the user authentication program 21 collates the input information with the user information table 50.

  When the input information (for example, user ID and password) matches the contents (user ID 50b and password 50c) stored in the user information table 50, the user authentication program 21 authenticates the user and provides the system. 10 is permitted, and the group to which the user belongs is recognized from the group 50 d of the user information table 50. On the other hand, if they do not match, the user authentication program 21 does not permit the use of the providing system 10 by the user.

  The user who is permitted to use can input a keyword (for example, “bonus”) from the key input unit 16. The number of keywords that can be input at one time is not limited to one, and may be plural. When entering multiple keywords at once, enter a space between the keywords (for example, if you want to enter two keywords, “Bonus” and “Salary”, at the same time, ").

  When the keyword is input in this way, the log information storage program 22 stores the log information related to the input keyword in the log information table 60 for each group 50d to which the user belongs and stores it in the storage device 18.

  FIG. 3 is a data structure diagram illustrating an example of the log information table 60 in which log information is accumulated.

  As an example, the log information table 60 includes items such as a log number 60a, time information 60b, and a keyword 60c. The log information table 60 may include a larger number of items as necessary.

  The keyword 60c is a keyword input from the key input unit 16, the time information 60b is information indicating the time when the keyword is input, and the log number 60a is a number assigned to each log information. When a new keyword is input to the log number 60a, “# 1” is added to the log information, and thereby the number of log information that has already been accumulated is incremented by one. Updated each time a new keyword is entered.

  FIG. 3 shows a log information table 60 when the group 50d is “C Labor Office” as an example. Since the group 50d is “C Labor Office”, the example shown in FIG. 3 indicates that many labor-related keywords such as “bonus” and “salary” have been searched in the past. In the log information table 60, the fact that a plurality of keywords are described in the keyword 60c column of the same log number 60a indicates that a plurality of keywords are input simultaneously. For example, the log number 60a “# 1” indicates that three keywords “bonus”, “salary”, and “condition” are simultaneously input to “July 24, 2018 11:27”.

  In the example shown in FIG. 2, “A call center” and “B laboratory” are shown as a group 50d in addition to “C labor office”. Therefore, in such a case, in addition to the log information table 60 of “C Labor Office” illustrated in FIG. 3, the storage device 18 has a data structure similar to that of FIG. The log information table of “A call center” and the log information table of “B laboratory” are also stored.

  When a new keyword (for example, “bonus”) is input for search by the authenticated user from the key input unit 16, the extraction program 23 stores the group to which the user belongs stored in the storage device 18. Based on the log information table 60 of 50d (C Labor Office), a keyword used simultaneously with the keyword (“bonus”) in the past search is extracted, and the extraction result is output to the providing program 24.

  The authenticated user can simultaneously input a plurality of new keywords (for example, “bonus salary”) from the key input unit 16 for searching. Also in such a case, the extraction program 23 searches the past information based on the log information table 60 of the group 50d (C labor office) to which the user belongs out of the log information table 60 stored in the storage device 18. The keywords used at the same time as these plural keywords (“bonus salary”) are extracted, and the extraction result is output to the providing program 24.

  The providing program 24 displays the keywords used at the same time as the keywords in the past search based on the extraction result by the extraction program 23 and the log information table 60 from the display 15 in the order of frequency of use, thereby prompting the user. , Provided as a suggestion keyword.

  FIG. 4 is a schematic diagram illustrating a display example of the suggested keyword list 70 displayed from the display 15 in response to input of one keyword (for example, “bonus”).

  FIG. 5 is a schematic diagram illustrating a display example of the suggest keyword list 71 displayed from the display 15 in response to two keywords (for example, “bonus salary”) being input simultaneously.

  As illustrated in FIG. 4, in the suggested keyword list 70, keywords that have been searched in the past at the same time as one input keyword (“bonus”) are shown according to the ranking 70 a. For example, in the example of the suggested keyword list 70 shown in FIG. 4, the keyword 70b most frequently searched in the past simultaneously with “bonus” is “salary”, and the number of searches 70c is 37 times. .

  As illustrated in FIG. 5, in the suggested keyword list 71, keywords that have been searched in the past simultaneously with the two input keywords (“bonus salary”) are shown according to the ranking 71 a. For example, in the example of the suggested keyword list 71 shown in FIG. 5, the most frequently searched keyword 70 b at the same time as “bonus salary” is “same day”, and the number of searches 71 c is 8 times.

  The user can select a keyword to be input to the search system 40 using the input keyword and the AND condition with reference to the suggested keyword lists 70 and 71. Although this selection process is not limited, it is performed by clicking one of the keywords 70b and 71b of the suggest keyword lists 70 and 71 displayed on the display 15 with a mouse or the like.

  The communication unit 17 is connected to a communication network 30 such as the Internet, for example, and communicates with an external search system 40 via the communication network 30. Through this communication, the keyword input by the key input unit 16 and the selected suggest keyword can be input to the search system 40. Further, the search result made by the search system 40 can be received in response to this input.

  For example, if the input keyword is “bonus” and the suggestion keyword selected accordingly is “salary”, “bonus” and “salary” are transmitted from the communication unit 17 via the communication network 30. The data is output to the search system 40, and the search system 40 performs a search using “bonus” and “salary” as keywords, and the search result is returned to the communication unit 17 and displayed from the display 15 as illustrated in FIG. 6. Is done.

  Further, if the input keyword is “bonus salary” and the suggestion keyword selected accordingly is “same day”, “communication”, “salary” and “same day” are communicated from the communication unit 17. The data is output to the search system 40 via the network 30, and the search system 40 performs a search using “bonus” AND “salary” AND “same day” as keywords, and the search result is returned to the communication unit 17. As illustrated, it is displayed from the display 15.

  The user can search for desired information by clicking the URL from the search results displayed as shown in FIGS.

  Next, an operation example of the suggestion keyword providing system to which the suggestion keyword providing method according to the first embodiment configured as described above is applied will be described with reference to flowcharts illustrated in FIGS. 8A and 8B.

  In the providing system 10, the user is limited in order to prevent the suggestion function from being contaminated. For this reason, the user authentication program 21 performs user authentication using a user ID, a password, or the like, and confirms that the user is an authorized user. Specifically, when using the providing system 10, the user inputs the user name 50a or the user ID 50b and the password 50c from the key input unit 16 in order to log in to the providing system 10 (S1).

  These pieces of information input from the key input unit 16 by the user are checked against the user information table 50 by the user authentication program 21 (S2).

  When the input information (for example, user ID and password) matches the content (user ID 50b and password 50c) stored in the user information table 50 (S2: Yes), the user is notified by the user authentication program 21. The user is authenticated and allowed to use the providing system 10 (S4). Further, the user authentication program 21 recognizes the group to which the user belongs from the group 50d in the user information table 50 (S5).

  On the other hand, if the input information (for example, the user ID and password) does not match the contents (user ID 50b and password 50c) stored in the user information table 50 (S2: No), the user is prompted by the user authentication program. 21, the use of the providing system 10 is rejected (S3).

  The user permitted to use in step S4 can input a keyword (for example, “bonus”) from the key input unit 16. The number of keywords that can be input at one time is not limited to one, and may be plural.

  After step S5, when a keyword is input from the key input unit 16 by the user (S6), log information related to the input keyword is stored in the log information table 60 by the log information storage program 22 for each group 50d to which the user belongs. The contents of the log information table 60 are updated and stored in the storage device 18 so that the log number 60a of the log information already accumulated is incremented by one. (S7).

  Next, based on the log information table 60 of the group 50d to which the user belongs (for example, “C Labor Office”) by the extraction program 23, the keyword (“bonus”) input in step S6 and past searches The keywords used at the same time are extracted, and the extraction result is output to the providing program 24 (S8).

  When a plurality of keywords (for example, “bonus salary”) are input at the same time in step S 6, these keywords (for example, “bonus salary”) are similarly extracted by the extraction program 23 based on the log information table 60. ) And keywords used simultaneously in the past search are extracted, and the extraction result is output to the providing program 24.

  Next, based on the extraction result of the extraction program 23 and the log information table 60 by the providing program 24, as shown in FIG. 4 and FIG. 5, for example, the keyword used simultaneously with the keyword in the past search is used. Are displayed from the display 15 in descending order. Thereby, a suggestion keyword is provided to the user (S9).

  FIG. 4 shows a display example of the suggested keyword list 70 displayed from the display 15 in response to the input of one keyword (for example, “bonus”). FIG. A display example of a suggested keyword list 71 displayed from the display 15 in response to the simultaneous input of keywords (for example, “bonus salary”) is shown.

  The user can select keywords to be input to the search system 40 using the input keywords and AND conditions with reference to the suggested keyword lists 70 and 71 (S10). Although this selection process is not limited, it is performed by clicking one of the keywords 70b and 71b of the suggest keyword lists 70 and 71 displayed on the display 15 with a mouse or the like.

  The keyword input in step S6 and the suggestion keyword selected in step S10 are input to the external search system 40 by the communication unit 17 via the communication network 30 such as the Internet (S11).

  In response to this input, a search is performed by the search system 40, and the result is returned from the search system 40 to the communication unit 17 via the communication network 30, and as shown in FIGS. 6 and 7, the display 15 (S12).

  The user can access desired information by clicking the URL from the search results displayed as shown in FIGS. 6 and 7 (S13).

  FIG. 6 illustrates a search result under an AND condition of two keywords, one keyword (“Bonus”) input in Step S2 and the suggestion keyword (“Salary”) selected in Step S6. Yes.

  FIG. 7 shows the search results under the AND condition of the three keywords, the two keywords (“bonus salary”) input in step S2 and the suggestion keyword (“same day”) selected in step S6. Illustrated.

  As described above, since the providing system 10 according to the first embodiment can limit users by authentication, use by an unspecified number of users can be excluded. Further, by accumulating log information of searches made by users belonging to the same group, the log information table 60 can be created for each group 50d. And a suggestion keyword can be provided based on the log information table 60 of the group 50d to which the user belongs.

  Therefore, not only can the log information table 60 be prevented from being polluted by an unspecified number of users, for example, log information including inappropriate keywords such as malicious information, but also log information including highly relevant keywords. Can be increased.

  And since a suggestion keyword is provided based on such a log information table 60, it becomes possible to provide the suggestion keyword which the user is seeking with high probability.

  Furthermore, when there are a plurality of suggestion keywords to be provided, the plurality of suggestion keywords can be displayed in the order of the frequency searched in the past, so that convenience for the user can be improved.

  Thus, the user can easily select a plurality of highly relevant keywords for the search system 40, and can access desired information with fewer search operations.

  Thus, according to the suggestion keyword provision system to which the suggestion keyword provision method according to the present embodiment is applied, it is possible to provide highly relevant suggestion keywords with high probability without being polluted.

(Second Embodiment)
A second embodiment of the present invention will be described.

  The suggest keyword providing system to which the suggest keyword providing method according to the embodiment is applied is a modification of the suggest keyword providing system to which the suggest keyword providing method according to the first embodiment is applied. Therefore, only different parts will be described below, and the same parts will be denoted by the same reference numerals.

  As described in the first embodiment, the log information is accumulated in the log information table 60 by the log information accumulation program 22. Thus, as log information is accumulated, the amount of data in the log information table 60 increases, and the time required for extraction processing by the extraction program 23 and provision processing by the provision program 24 also increases. Also, old log information may contain keywords that are not very useful.

  Considering such circumstances, in this embodiment, the extraction program 23 and the providing program 24 do not target all the log information included in the log information table 60, but refer to the log number 60a, for example, Extraction processing for only a specific number of log information so that only the latest 1000 pieces of log information (that is, log information whose log number a is “# 1” to “# 1000”) are targeted And provide processing.

  Alternatively, the extraction program 23 and the providing program 24 refer to the time information 60b and perform extraction processing only on log information accumulated in a limited period, for example, so as to target log information for the past 10 years. Alternatively, the providing process may be performed.

  Furthermore, as a modified example, the extraction program 23 and the provision program 24 are stored in a specific season such as a specific period such as the year-end and New Year holidays, the end of the fiscal year, and the end of the period with reference to the time information 60b. You may make it perform an extraction process and a provision process only for log information.

  As an example of this, an example in which the providing system according to the present embodiment provides a suggestion keyword for the log information accumulated at the “year-end” for a user belonging to the group 50d named “C Labor Office”. explain.

  For example, according to a user working at C Labor Office, when the “year-end” from the first day of February to the end of March is reached every year, the search system 40 is given a “year” such as “retirement”, “joined”, “transfer”. It is assumed that the frequency of inputting a keyword unique to “end” is significantly higher than in other periods.

  In such a case, users belonging to the group 50d called “C Labor Office” extract the log information from the past February 1 to March 31 with respect to the extraction program 23 and the provision program 24. Specify processing and provision processing.

  Or, on February 1 every year, until March 31, the extraction program 23 and the provision program 24 are extracted and provided for the log information from the past February 1 to March 31. It may be programmed to perform processing.

  In response to this, when a keyword is input at “year end”, the extraction program 23 and the provision program 24 perform extraction processing and provision processing on the past “year end” log information.

  Accordingly, the providing system according to the present embodiment is more relevant by limiting the log information considered for the extraction process and the provision process performed by the extraction program 23 and the provision program 24 to a specific season. The terms can be provided to the user as a suggestion keyword with a higher probability.

  Further, by applying this, the log information may be limited according to the usage as well as being limited to the season.

(Third embodiment)
A third embodiment of the present invention will be described.

  The suggest keyword providing system to which the suggest keyword providing method according to the embodiment is applied is a modification of the suggest keyword providing system to which the suggest keyword providing method according to the first embodiment is applied. Therefore, only different parts will be described below, and the same parts will be denoted by the same reference numerals.

  FIG. 9 is a data structure diagram illustrating an example of the log information table 61 applied in the providing system according to the third embodiment.

  The log information table 61 shown in FIG. 9 includes items such as a log number 60a, time information 60b, a keyword 60c, and a user ID 60d. That is, the log information table 61 shown in FIG. 9 has a data structure including the user ID 60d in the log information table 60 shown in FIG.

  In the providing system according to the present embodiment, as described in the first embodiment, the authentication program 21 authenticates the user and recognizes the group 50d to which the user belongs.

  Then, in the extraction program 23 and the providing program 24, the extraction is performed not for all the log information included in the log information table 61 but for only the log information of the authenticated user with reference to the user ID 60d. Perform processing and provision processing.

  In the providing system according to the present embodiment, by using the log information table 61 as shown in FIG. 9, the extraction program 23 and the providing program 24 use the log information table 61 as shown in FIG. Processing can be performed.

  As a result, the user can extract a suggestion keyword in consideration of log information specialized for the user.

  The best mode for carrying out the present invention has been described above with reference to the accompanying drawings, but the present invention is not limited to such a configuration. Within the scope of the invented technical idea of the scope of claims, a person skilled in the art can conceive of various changes and modifications. The technical scope of the present invention is also applicable to these changes and modifications. It is understood that it belongs to.

  For example, by adding a new item to the log information table, it is possible to arbitrarily customize the log information considered when extracting and providing keywords.
