Description

  The present invention relates to a technique for managing operation history information of a user and searching for information browsed in the past by the user.

As an example of a service that manages and allows reuse of information viewed by conventional individuals,
“Favorites” and “History”, which are Internet Explorer functions provided by Microsoft Corporation, are applicable.

  Information managed by “favorites” is a folder, a Web page title, a URL, a display count, and a last display date and time. When using a Web page managed by “Favorite”, the user looks for the title of the Web page and searches for the desired Web page. Also, create a folder for organizing those Web pages, give a name such as J-League, for example, and store the URL of the Web page related to J-League in that folder to search for the desired Web page It can also be made easier.

  The information managed by “History” is the last display date, Internet address, title, and number of uses. When using a Web page managed by “history”, the user can sort by date order, site order, and number of times of use, and look for the desired Web page by looking at the title of the Web page. Also, by inputting a keyword, it is possible to display a list of Web pages including the keyword from Web pages viewed in the past.

  However, “favorite” and “history” can acquire only a few items of the operation history of the user, and are insufficient to calculate an experience score indicating the strength experienced by the user.

  On the other hand, as means for searching for information on the Internet, there are Google provided by Google and goo provided by NTT Resonant.

  These are techniques for displaying search results only from information on the Web page itself such as words and link structures. In other words, the search result is displayed regardless of whether or not the Web page has been viewed by the individual performing the search.

Also, as a technique, a method has been proposed in which operation history of a certain user is collected, an evaluation value is calculated for each URL from the operation history, and URLs highly evaluated by other users who are similarly evaluated are displayed. (For example, see Patent Document 1).
JP-A-10-307845

  When a user wants to obtain “information about a certain matter” and searches using Google or Google, there are hundreds or thousands of search results, and all search results cannot be confirmed. is there. This is because Google and Google display in the order of the degree of suitability to the search keyword by a unique ranking method, and this ranking is fixed.

  In addition, Web pages viewed in the past may be more effective for the user. For example, a Web page that has been viewed in the past is easier to understand “information about a certain matter” than a Web page that has not been viewed in the past. Since it is possible to guess to some extent what information is written, it is possible to reach “information about a certain matter” in a Web page in a short time, and to understand “information about a certain matter” by holding a point.

  On the other hand, even if the user remembers the content many times in the past, information that is not desired to be displayed in the search result is displayed at the top. In other words, it may be a factor that increases labor for searching for a new Web page that has not been seen in the past.

  And with existing technology, you can search from a page you have seen in the past using a small operation history and display the search result, or whether you have seen it in the past or not The search is performed, and the search result is displayed without considering the page seen in the past. That is, the experience score indicating the strength experienced by the user cannot be calculated sufficiently.

  In addition, it is easy to understand which search results are displayed based on search results using experience scores that indicate the strength experienced by users and search results based on fixed scores such as Google and Google. It cannot be displayed to the user in a way that can be done.

  Therefore, a technique is provided for searching for files that have been viewed in the past, calculating an integrated fitness score from a detailed browsing history, and searching for files that are considered important.

  Hereinafter, embodiments will be described with reference to the drawings.

  A block diagram of the search device 10 is shown in FIG. As shown in FIG. 1, the search device 10 includes an operation history acquisition unit 11, an operation history DB 12, a FILE attribute information DB 13, an experience score calculation unit 14, a FILE search unit 15, an all page search unit 16, a display management unit 17, and an integrated ranking. A calculation unit 18 and a search management unit 19 are included.

  First, a method in which the operation history acquisition unit 11 acquires an operation history will be described.

  The operation history acquisition unit 11 acquires a window message globally communicated on the Windows (registered trademark) OS when a state change event occurs in a keyboard event, a mouse event, an active window, or the like ( Hook) and identify which program is currently being manipulated by the user. In addition, it can be acquired that any one of the windows is activated or deactivated. In this embodiment, a case where Microsoft Internet Explorer (IE) is used will be described as an example.

  Next, it communicates with the IE by inter-program communication, and acquires the URL of the home page currently displayed on the IE window and the displayed information body (in many cases, an HTML file).

  Next, a hash value is calculated for the acquired information body using MD5.

  Next, the acquired information body is stored as “FILE seen in the past”. Here, it is possible to save in the hard disk or in FILEDB.

  Next, the window activation time included in the window message is estimated to be the URL browsing start time, and the URL, browsing start time, hash value calculated using MD5 for the information body, and the information body are stored. The registered file name (file path) is registered in the operation history DB 12.

  Next, the operation history acquisition unit 11 uses the result of analyzing the information main body and the already acquired information to calculate the author, title, update date, and information main body that are attribute information of the information main body using the MD5. The value, the URL published on the Internet, and the file name (file path) storing the information body are stored in the FILE attribute information DB 13.

  Thereafter, when the operation history acquisition unit 11 receives a window deactivation message included in the window message, the time is estimated to be the URL browsing end time, and the browsing end time is registered in the operation history DB 12.

  Next, a procedure in which the search device 10 performs a search will be described.

  The search management unit 19 receives, from the information search terminal 30, a search keyword, a file display distribution specifier (“1: 1 ratio = alternately displays files with higher integrated ranking and files with higher general ranking”), and The calculation method identifiers (“prior author = Taro; otherwise = default”, “browse the viewing time of 5 minutes or more; otherwise = default”, “experience score: FILE conformity score = 7: 3”) are received.

  Then, by searching the operation history DB 12, a path list of files in which FILEs seen in the past are stored is acquired. The search management unit 19 sends the search keyword, the file path list, and the calculation method identifier (“prior author = Taro; other = default”) to the FILE search unit 15.

  The FILE search unit 15 searches a FILE seen in the past using the search keyword and the file path list, and calculates a FILE match score indicating the degree of match between the search keyword and FILE for each FILE. Then, the result is transmitted to the search management unit 18. An existing technique can be used for calculating the FILE conformity score, and the setting of the calculation method can be changed.

  At this time, it is checked by accessing the FILE attribute DB 13 whether or not the writer is Taro, and the FILE fitness score of FILE whose author is Taro is doubled.

  The search management unit 19 transmits a calculation method identifier (“browsing for 5 minutes or longer; otherwise = default”) to the experience score calculation unit 14.

  The experience score calculation unit 14 calculates the experience score by accessing the operation history DB and calculating the browsing time length of a file browsed in the past. At this time, the browsing time of 5 minutes or more is rounded down to 5 minutes. Then, the experience score is calculated as 1 point per second for viewing time. Then, each file and a list of experience scores of each file are transmitted to the search management unit 19.

  The search management unit 19 performs integrated fitness ranking calculation on the path of each file, the experience score of each file, the list of FILE fitness scores of each file, and the calculation method identifier (“experience score: FILE fitness score = 7: 3”) To the unit 18.

  The integrated suitability ranking calculation unit 18 calculates a sum of a value obtained by multiplying the file suitability score by 0.3 and a value obtained by multiplying the experience score by 0.7, thereby calculating an integrated suitability score. Then, the ranking (integrated ranking) for each file in the files browsed in the past is calculated based on the integrated fitness score, and the path list of each file and the integrated ranking list are transmitted to the search management unit 19.

  The search management unit 19 transmits the search keyword to the all page search unit 16.

  The all-page search unit 16 searches for files in a searchable range including files that the user has not browsed in the past using a search keyword, and acquires the files regardless of the browsing history. Then, a general matching score indicating the degree of matching between the search keyword and the searched file is calculated.

  Further, the ranking (general ranking) in the entire file is calculated for each file based on the general fitness score, and the file path and the general ranking list of each file are transmitted to the search management unit 19. Here, the integrated ranking and the general ranking are independently assigned to each file.

  The search management unit 19 displays a file display allocation specifier (“1: 1 ratio = alternately displays files with higher integration ranking and files with higher general ranking”), file paths, and integration of files. The ranking and the general ranking list of each file are transmitted to the display management unit 17.

  In the display management unit 17, based on the file display distribution specifier (“1: 1 ratio = alternately display files with higher integrated ranking and files with higher general ranking”), the file with the higher integrated ranking. And assigning the display location to the file with the highest general ranking.

  That is, the file with the highest integrated ranking and the file with the higher general ranking are alternately displayed. In addition, since both integrated ranking and general ranking are given to files that have been viewed in the past, they are displayed in the integrated ranking in the search results and also displayed in the general ranking, and may be assigned to two locations. is there.

  The display management unit 17 transmits a file path and a list of file display location information of each file to the search management unit 19.

  The search management unit 19 creates a search result page based on the file path and the list of file display location information of each file, and transmits it to the information search terminal 30.

  Here, a screen displayed by the information search terminal 30 is shown in FIG. As shown in FIG. 2, when a user who operates the information search terminal 30 makes a search request, the user inputs a search keyword (goo), a file with a higher integrated match rank, and a file with a higher general match rank. It is possible to operate a bar that adjusts a file display distribution specifier (“1: 1 ratio of display locations”) that is a display distribution and a bar that adjusts the weighting of the experience score and the FILE conformity score.

  Note that the user operation history may be acquired from the operation history acquisition unit 11 or may be registered by a registration request from an application of another user terminal such as Internet Explorer. In some cases, the user may register from a Web server that requested information to be viewed.

  The search program for executing the search device 10 can be installed on a single server, an existing search server, or the user terminal 30.

  Further, the operation history DB 12, the FILE attribute information DB 13 and / or FILELED may be installed outside the search device 10 to be accessible.

  As described above, it is possible to search for a file that has been viewed in the past based on the experience score and the FILE matching score, and to search for a Web page that matches the search keyword based on the general matching score. It is possible to display these two types of search results at the same time and clearly by which search condition the file is searched.

  Since a file with a high experience score is considered to be a file that typically represents an action that has been performed in the past, it is also possible to recall an action that has been performed in the past in a shorter time.

  In addition, when a file with a high experience score is viewed again, the content of information can be acquired in a relatively short time compared to information that has been weakly experienced (for example, only for a short time) in the past.

  Also, by displaying both files that have been viewed in the past and files that have been searched regardless of whether or not they have been viewed in the past, the user can determine whether the file is displayed at the top based on his / her history. Regardless of the history, it was difficult to understand the basis of the search results because the files were generally ranked in the top. However, just by understanding the mechanism of adjusting the display location of the search, the user can determine whether the file is displayed at the top based on his / her history, or the file generally ranked at the top regardless of his / her history. Can understand easily.
