Description

  The present invention is a document display device capable of appropriately grasping a user's request and flexibly displaying content that matches the problem, reflecting a dynamically changing user's situation, and providing a display technique according to the user's situation. And a document display method.

  When an electronic document is stored, a search when the electronic document is used later becomes a problem. Conventionally, in the case where a document is text information, the features of the text are indexed as keywords, and the target document is extracted by searching this. In order to intuitively recognize the target document, thumbnails are frequently used. However, since the thumbnail is a reduced image of the original image, the user can recognize only a rough appearance of the image when searching. In addition, displaying a large number of thumbnails that may include the target document on the display screen may hinder search and may hinder the use of an effective display screen.

In recent years, a temporary (temporary) screen called a pull-down menu or pop-up window is also displayed to compensate for the poor display content. The temporary screen is displayed corresponding to the object instructed (pointed) with the mouse or the like, and is erased when the pointing is stopped. Such a temporary screen has an advantage that it is possible to easily grasp the rough appearance of the electronic document without complicating the display screen. Conventionally, on such a temporary screen, information prepared in advance is only displayed in a predetermined format, and information that the user really needs is not always displayed.
JP-A-11-149485 Japanese Patent No. 3245038 JP 11-39293 A JP 2000-250919 A

  A conventional solution to this problem is described in Patent Document 1. According to this process, feature values and character strings of stored document images are calculated (recognized) in advance, and clustering (classification) based on the results is performed. A cluster that matches it is selected. Since this is a clustering that depends only on the feature amount of the accumulated document data, it can be prepared in advance, and although it is not disclosed in the text, it may be displayed on a temporary screen. However, since the features and tendencies regarding the user are ignored, the display content for the same data is fixed.

  Patent Document 2 describes a method of statistically analyzing key information operated by a user for document creation and presenting advice that seems most desirable to the user. The subject of this patent is document creation means, and there is no disclosure regarding the temporary screen. Furthermore, Patent Document 3 includes a data series that monitors user operation characteristics and is classified according to business. Based on the characteristics of the user who uses the document, how the document is used is added as a document attribute, and the document is associated with the business. This system can recognize user characteristics and provide a document most suitable for the current user. There is no disclosure regarding the temporary screen, and the amount of information is too large to process in real time.

  In Patent Literature 4, when an existing stored document is classified, the word W having the strongest correlation with the nth classification is associated as a representative word of the classification n. Since the word W is used instead of the classification number n, the user can easily understand. Again, there is no description regarding the use of the temporary screen.

  A recently proposed method for such a past defect is a composite display means to which a new function is added. For example, in the second display frame attached to the thumbnail, static important information such as the title and author in the document is enlarged and displayed in parallel.

  However, the problem still remains and users do not always want the same information, nor do they want to search for information in the same format. The system only needs to be able to appropriately grasp the user's request and flexibly display the content that matches the problem, but in any of the conventional examples described above, it reflects the user's situation that changes dynamically, and a display method according to it Can not provide.

  Embodiments of the present invention will be described below. FIG. 1 is a block diagram showing a document display apparatus of the present invention. In FIG. 1, a document display apparatus 1 includes a pointing device 11, an information storage unit 12, an information extraction unit 13, a history recording unit 14, a temporary information display unit 15, an operation status monitoring unit 16, and a monitor information analysis. It comprises means 17 and document file association information analysis means 18.

  The pointing device 11 can designate a predetermined document file (original document file D). The information storage unit 12 can store predetermined information (such as an attribute information file) related to the original document file D. The information extraction unit 13 can extract predetermined information regarding the original document file D instructed by the pointing device 11 from the information storage unit 12. The history recording unit 14 can record an operation history of the pointing device 11 or a real-time calculation result depending on the operation history. The temporary information display means 15 can display the predetermined information (attribute information file or the like) extracted by the information extraction means 13 as temporary information on the temporary screen. The temporary information display means 15 can reflect and display the real-time calculation result recorded in the history recording means 14. The operation status monitoring means 16 can monitor the user's operation status (including usage information). The monitor information analyzing means 17 can statistically analyze the information monitored by the operation status monitoring means 16. The document file association information analyzing unit 18 can statistically analyze an attribute information file associated with the original document file D.

  Hereinafter, a case where a pull-down menu is used as a temporary screen displayed by the temporary information display unit 15 will be described. As shown in FIG. 2, the predetermined information DI associated with the original document file D to be processed is attached to the original document file D as an attribute information file such as a feature file. These are associated with each other by a pointer or a hierarchical relationship. FIG. 2 shows a state in which the attribute information file includes a thumbnail file, a text file, an index file, and a user characteristic file.

  When a user uses an electronic file, a program for managing the filing system monitors how the user uses a document as shown in FIG. 3 and learns its user characteristics. In FIG. 3, the user input A1 is sent to the time counter A5 and detected as character information A2 or instruction information A3. The character information A2 input by the user is sent to the statistical processing means A4. The instruction information A3 input by the user is sent to the statistical processing means A4 as character information A2 when it is a text document, and as graphic information A4 when it is a graphic. The learned user information is updated as needed and stored in the user characteristic file A5. Examples of user information include a user ID, a frequency by use file, a frequency by display mode, a pull-down menu holding time, and the like.

  FIG. 4 shows an example of a pull-down menu display. When a pointing device (for example, a mouse) is continuously clicked on a specific icon, a thumbnail that is one of related files depending on how long the click state is maintained. Are displayed sequentially in seconds. According to this method, a plurality of pages are sequentially displayed until the display device is full.

  By canceling the click state, this display can be stopped and deleted. The user information in this case is the time during which the click state is held. In order to cancel the click, a double click, a right click, an ESC key, or the like is a promising candidate.

  FIG. 5 shows another embodiment. When an icon corresponding to a specific file is continuously clicked with a pointing device (for example, a mouse), depending on the time during which the clicked state is maintained, thumbnails that are one of the related files are sequentially displayed in units of several seconds, S1, S2. The images are enlarged and displayed in the order of S3. This function is useful when you want to enlarge and confirm a specific page.

  FIG. 6 shows an example in which different related files are opened sequentially by repeatedly clicking. In this example, a thumbnail T1, a feature text T2 indicating a rough content such as a keyword, and a preamble text T3 indicating a detailed content such as a full text document are sequentially displayed. If the user property file stores the access frequency of the file to be used and the related file used in the past for each user, the display order can be predicted and matched to the operation status of the user.

  FIG. 7 shows an example in which a keyword is used as related information. In many cases, the type of keyword index and the number of keywords are fixed, but in this example, keywords frequently used are preferentially extracted from the past usage history of the same user. Languages that are easily recalled by the same user tend to be biased, and keywords are keyword candidates extracted from document files (usually high-frequency general words are excluded, and candidates that are semantically close to the topics of the target document are preferentially extracted. And the weighted addition value of the high-frequency keyword used by the same user in the past. A principal component analysis is performed on the extracted keyword attribute vector (for example, importance, relevance to predicate, saliency, relative appearance frequency, etc., which are generally variables), and the first principal component and the second principal component are analyzed. It is plotted on the plane of the main component. This makes it possible to intuitively visualize the main features of the keywords constituting the contrast document. Since the principal component analysis results depend on a given sample group (in this case, a related keyword group), it is necessary to calculate instantaneously in order to display the result on the pull-down menu. When the number of samples is several tens, there is no technical difficulty. However, the main components often have unclear physical concepts and meanings. Therefore, it becomes easier to understand if the characteristic closest to the main component is temporarily displayed. The arrows in the figure indicate the direction of the parameter closest to the first principal component and its name. Such principal component analysis is suitable for displaying data in which the nature of the parameter to be expressed is unclear.

  FIG. 8 shows a more detailed specific example. In this figure, the vertical direction indicates the thesaurus hierarchy, and the upper level indicates the higher level concept. The horizontal direction shows the relevance between words, and the distant one is less relevant. Vertical broken lines indicate different concepts and classifications. In general, the importance as a keyword is more effective as the concept of a word is lower (the concept is narrower). Therefore, in many cases, the lower order of the thesaurus is more important. The following table shows examples of the vector values.

  9 to 11 show other examples in which the display contents change according to the click state holding time of the pointing device. If the clicked state is held as 1 second or 2 seconds, the images can be sequentially switched or additionally displayed. In each figure, the time after access is shown on the horizontal axis, “M” indicates minutes, “H” indicates hours, “D” indicates days, and “W” indicates weeks. FIG. 9 shows a state in which the display is reduced while being changed to thumbnails S1 to S5 according to the click state holding time of the pointing device. FIG. 10 shows a state in which the display is reduced in the horizontal direction while being changed to thumbnails S1 to S5 in accordance with the click state holding time of the pointing device. Further, FIG. 11 shows a state in which the display is changed to thumbnails S1 to S5 in accordance with the click state holding time of the pointing device and the file color is reduced in accordance with the importance.
