Description

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

  As an example of a conventional service for managing information viewed by an individual and enabling reuse, “Favorite” and “History”, which are functions of Internet Explorer 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 it a name such as J-League, and store the URL of the web page related to the 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 times of use. When using a web page managed by “history”, the user can sort by date, 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. When “History” is used, a search keyword is input, and when a file to be hit as a search word is set in time series, all the files browsed in the past are displayed in time order.

  However, “Favorites” and “History” can acquire only a small number of items in 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.

In addition, for example, 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, refer to 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 and where, 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” at a point.

  On the other hand, even if the user remembers the content many times in the past and the information is not desired to be displayed in the search result, it may be 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've seen in the past using a little operation history and display the search results, or whether you've seen it in the past The search results are displayed without considering that the search is a page that has been viewed in the past. That is, the experience score indicating the strength experienced by the user cannot be calculated sufficiently.

  In addition, when a search keyword is input and a file to be hit in the search word is time-sequentially, all the files browsed in the past are displayed in time order, so that a large number of search results are displayed. Therefore, after all, it was necessary to check a large number of files and find out important files.

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

In order to solve the above problem, the invention according to claim 1 is a file search performed by a file search apparatus that inputs a search request and searches for a file based on information stored in an operation history database and a file attribute information database.

In the first to seventh aspects of the invention, the integrated score is calculated from the experience score calculated based on the degree of matching with the search request and the browsing time of the file, and the file as the search result is searched based on the integrated score. . In addition, it is possible to set the degree of matching and the degree of experience score contribution in the integrated score calculation.

According to the first to seventh aspects of the present invention, it is possible to provide a search file based on a search request and the importance of time browsed in the past. Further, it is possible to set the search request and the importance of the time browsed in the past, and set the weighting to a desired value.

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

  A block diagram of the search device 10 is shown in FIG. As illustrated in FIG. 1, the search device 10 includes an operation history acquisition unit 11, a FILE attribute information DB 12, an operation history DB 13, a FILE search unit 14, an experience score calculation unit 15, a temporal peripheral file extraction unit 16, and an integrated score calculation unit. 17 and a search management unit 18.

  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 activation time of the window included in the window message is estimated to be the URL browsing start time, and the URL, the browsing start time, the 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 13.

  Next, the operation history acquisition unit 11 uses the result of analyzing the information body and the already acquired information to calculate the author, title, update date, and information body, which are attribute information of the information 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 12.

  After that, when the operation history acquisition unit 11 receives a window deactivation message included in the window message, the operation history acquisition unit 11 estimates the time as the URL browsing end time and registers the browsing end time in the operation history DB 13.

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

  The search management unit 18 receives a search keyword, time information desired to be searched (for example, “February 20, 2005, 16:16:41”) and a calculation method identifier (“prior author = Taro; Others = Default ”,“ Browsing time of 5 minutes or more; Others = Default ”,“ Experience score: FILE conformity score = 7: 3 ”).

  Then, by searching the operation history DB 13, a path list of files in which FILEs seen in the past are stored is acquired.

  The search management unit 18 sends the search keyword, the file path list, and the calculation method identifier (“prior author = Taro; other = default”) to the FILE search unit 14.

  The FILE search unit 14 searches for FILEs that have been seen in the past using the search keyword and the file path list, and calculates a FILE match score, which is the degree of suitability for the search request, 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 12 whether or not the writer is Taro, and the FILE fitness score of FILE whose author is Taro is doubled. In addition, the FILE conformity score of a file that does not include the search keyword (does not hit the search) is “0”.

  The search management unit 18 transmits the calculation method identifier (“browsing for 5 minutes or longer; otherwise = default”) to the experience score calculation unit 15.

  The experience score calculation unit 15 accesses the operation history DB 13 to calculate the browsing time length of a file browsed in the past, and calculates an experience score. 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 of browsing time. Then, the path of each file and the list of experience scores of each file are transmitted to the search management unit 18.

  The search management unit 18 integrates the path of each file, the experience score of each file, the list of FILE conformity scores of each file, and the calculation information identifier (“experience score: FILE conformance score = 7: 3”). Send to.

  The integrated score calculation unit 17 calculates the sum of a value obtained by multiplying the file conformity score by 0.3 and a value obtained by multiplying the experience score by 0.7 to obtain an integrated score. Then, a path of each file and a list of integrated scores of each file are transmitted to the search management unit 18.

  The search management unit 18 sends to the temporal peripheral file extraction unit 16 time information (for example, “February 20, 2005, 16:16:41”), the path of each file, and the integrated score of each file. Send the list.

  The temporal peripheral file extraction unit 16 searches the operation history DB 13 based on the time information desired to be searched, for example, the path of the file that was browsed in the three hours before and after the time desired to be searched.

  Next, a file having a higher integrated score is extracted from the searched file path by the specified number of thumbnails (for example, 23).

  Next, the file having the higher integrated score and the file integrated score of these files are transmitted to the search management unit 18.

  The search management unit 18 creates a search result page in which files with higher integrated scores are arranged two-dimensionally in time series, and transmits the search result page to the information search terminal 30.

  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, a search keyword (goo), time information to be searched (“February 20, 2005, 16:16:41”), How long before and after the time information you want to search for ("6 hours"), the period information indicating how to display the file you want to display in the search results, the weighting of experience score and FILE conformity score, and the number of files to display It is possible to specify. 2 shows a screen in which the number of files is narrowed down to 10 in the screen of FIG.

  Further, as shown in FIG. 4, a button for displaying a file browsed in the time vicinity of the file is arranged in the search result of the file search browsed in the past in the past. It is also possible to make a search request possible.

  Note that the search device program for realizing the search device 10 can be installed in a single server, an existing search server, and the user terminal 30.

  In addition, the user operation history information may be acquired from the operation history acquisition unit 10 or may be registered 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.

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

  As described above, in the present embodiment, it is possible to search for a file having a high experience score and a high file matching score in a file that has been seen in the past.

  In addition, it is possible to search for a file having a high experience score and a high file suitability score from files browsed around the time designated by the user.

  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, it is considered that the content of information can be acquired in a relatively short time compared to information experienced in the past (for example, only for a short time).
