It is possible to improve the readability when referring to.

  For example, since work is grouped according to work and interest, it is possible to browse the history with a focus on one work even for a history of performing a plurality of work simultaneously. Further, by displaying a hierarchical structure having a parent-child relationship in a tree format, it becomes easy to grasp the transition of past work.

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

(Configuration of history creation device)
FIG. 1 is a configuration diagram of a history creation apparatus used in the embodiment of the present invention. As illustrated in FIG. 1, the history creation device includes an input unit 11 that receives input from a user, a visualization unit 12 that visualizes a history, a history DB 14 that stores a history, an output unit 13 that outputs a visualization result, and a user's User activity monitoring unit 15 for monitoring activities, document display unit 16 for displaying documents, document storage unit 17 for storing documents, association calculation unit 18 for calculating history association, and history related information are stored. The history related information DB 19.

(Creation of history DB 14)
First, creation of the history DB 14 will be described. The user starts an application (document display unit 16) on the personal computer and displays the document stored in the document storage unit 17 on the screen of the personal computer. When a user works on a personal computer, a plurality of applications are often started at the same time, and thus a plurality of documents are often displayed on the personal computer.

  Examples of applications include a text editor, document creation software (word), spreadsheet software, presentation software, PDF display application (Adobe Acrobat), Web browser, mailer, and the like.

  Of these, when a Web browser is used, the displayed Web page is often stored on the Internet and is not stored in the document storage unit 17 in the personal computer, but the Web page displayed on the Web browser Can be handled in the same manner as other applications by providing the Web browser with a function of storing all of these in the document storage unit 17.

  The user activity monitoring unit 15 operates as software resident on the personal computer, and monitors user operations (keyboard event, mouse event, link click, text cut and paste, file save event, active window information, etc.) The history information is stored in the history DB 14 together with the time. Here, a data structure example of the history DB 14 is shown in FIG. As shown in FIG. 2, time, user operation, and additional information are stored in association with each other.

  In particular, when the active window is changed, a document ID (for example, a file name and a URL) displayed from the document display unit 16 is received. In order to realize this mechanism, the application that is the document display unit 16 needs to have a function of transmitting a document ID in response to a request from the user activity monitoring unit 15. Further, when the information that becomes the cause can be detected when the active window is changed, the information is also saved. For example, when a new window is opened by clicking a link on a Web page, the link source information is saved.

  That is, when the active window is changed, the user activity monitoring unit 15 stores the application name, the document ID opened by the application, and link source information in the history DB 14 together with the time.

(Creation of history related information DB 19)
Next, creation of the history related information DB 19 will be described. FIG. 3 shows an example of the data structure of the history related information DB 19. As shown in FIG. 3, the history related information DB 19 stores time, parent information, time, title, related reason, and type in association with each other. The creation of the history related information DB 19 is executed at a time specified by the user or at a time when the load on the personal computer is low.

  The relation calculation unit 18 refers to the history of the active window operation from the oldest information in the history DB 14, determines a parent and a child according to the following rules, and stores them in the history related information DB 19.

  (1) A time period from an operation history of a certain active window to the next active window operation history is less than a certain time (for example, 2 seconds or less) is excluded.

  (2) The oldest history information has no parent.

  (3) If link source information exists in the operation history of a certain active window, the operation history of the active window having the document ID of the link source is searched from the history in the direction of the old time. Is the parent and the current active window is the child.

  (4) If the link source information does not exist, the document storage unit 17 is accessed in comparison with the previous history information and the text content similarity is checked (for example, the keywords extracted from the text match). If the result is similar, the previous history information is set as a parent, and the current active window is set as a child. If the result is not similar to the previous one, check the similarity between the previous history information and the content, and if the result is similar, the previous history information is the parent, Make the current active window a child. Similarly, the previous three and the previous four are repeated up to the number set by the user. In the case of a search engine page instead of a general Web page, the similarity is checked using only the search keyword.

  In the case of determination based on matching of keywords, if a general noun is used as a keyword, there is a possibility that it is always “similar”. Therefore, by extracting a keyword using a specific expression extraction device using the technique disclosed in Japanese Patent Laid-Open No. 2001-318792, it is possible to solve the problem of “similar” at all times.

  (5) When a cut and paste event has occurred, the cut active window information is used as a parent, and the pasted active window is used as a child.

  (6) An active window operation history that does not match the above 1 to 5 is assumed to have no parent.

(Example of parent-child relationship calculation)
Here, FIG. 4 shows a parent-child relation calculation example. As shown in FIG. 4, it is assumed that the oldest active window 41 has no parent. The active window 42 moved by linking and clicking the active window 41 has the active window 41 as a parent.

  When there is no link source information for the active window 43, the document storage unit 17 is accessed and compared with the active window 42 which is the previous history information, and the similarity of the contents of the text is checked. If the result is that the active window 43 and the active window 43 are similar to each other, the active window 42 that is the previous history information is set as a parent, and if not similar, the active window 43 has no parent.

  The active window 44 moved by link-clicking the active window 43 has the active window 43 as a parent.

  If a cut and paste event has occurred for the active window 44, the cut active window 44 is used as a parent, and the pasted active window 45 is used as a child.

(Visualization)
Next, visualization will be described. First, the user inputs display range information (display date and range) from the input unit 11. The input unit 11 sends display range information to the visualization unit 21. The visualization unit 21 acquires history information matching the display range information from the history related DB 19. The visualization unit 21 creates a tree-type image from the parent-child hierarchical structure information acquired from the history related information DB 19.

  Here, a tree format image will be described with reference to FIG. As shown in FIG. 5, the user searches the keyword “Windows XP sp2” using the Google web search at 2004/10/01/17: 33: 26, and obtains the search result. The active window of this search result is a parent, and is linked to [Windows XP sp2 FAQ collection] and [Windows XP Service Pack2 security enhanced function installed] which are search results. Thereafter, a similar search is performed using [Windows XP sp2 proxy] as a keyword, and it is found that the search result is linked. In addition, after a link to [Windows XP sp2 FAQ template], which is a similar search result using [Windows XP sp2 failure] as a keyword, the cut and paste operation for [Precautions when applying SP2] in the active window Has been made.

  In addition, there are no parent and child for the active window of [meeting] and [schedule].

  In this way, the history of the search performed by the user and the activity history such as the link history are displayed in an easily understandable manner hierarchically.

  The output unit 13 receives and outputs such an image.

  In the above-described embodiment, the history creation device is realized by, for example, a CPU included in a computer device that configures the history creation device, and performs application of necessary calculation processing, user activity monitoring processing, document display processing, visualization processing, and the like Can be installed as a program.

  Also, it is possible to write / read data such as the results of processing and calculation results, such as necessary related calculation processing, user activity monitoring processing, document display processing, visualization processing, etc., to an internal memory or an external storage device. Good.

  In addition, a recording medium recording software program codes for realizing the functions of the present embodiment is supplied to a system or apparatus, and a CPU (MPU) of the system or apparatus reads and executes the program code stored in the storage medium. It is also possible. In this case, the program code itself read from the storage medium realizes the functions of the above-described embodiment, and examples of the storage medium storing the program code include CD-ROM, DVD-ROM, and CD-R. , CD-RW, MO, HDD and the like.
