Description

  The present invention relates to an information display system, an information display method, and an information display program for displaying an electronic document, and more particularly, to an information display system, an information display method, and an information display program for displaying an electronic document including a plurality of areas.

  In recent years, electronic documents that require a large amount of information and high resolution, such as Web pages on the Internet, are often viewed on terminals other than personal computers such as mobile phones and televisions. For this reason, attention has been focused on a technology that allows a user to browse a Web page comfortably even with a terminal that has lower operability or lower resolution than a personal computer. As one of such techniques, a technique for efficiently browsing contents by displaying a Web page in a reduced size and partially displaying an area to be browsed has been proposed (see Patent Documents 1 and 2).

  For example, in Non-Patent Document 1, in a mobile phone which is a small screen terminal, the horizontal width of a Web page is relatively reduced to fit the screen width, and a rectangular frame displayed on the screen is further operated. A function for enlarging and displaying the area within the frame is introduced. By using this function, it is easy to look down on the entire Web page, so that an overview of the Web page can be grasped.

  Patent Document 3 proposes a technique for partially enlarging and displaying only a specific segmented area (hereinafter referred to as a block) in a reduced electronic form. If this technique is used, an electronic document can be browsed in units of blocks.

  On the other hand, Patent Document 4 proposes a technique for changing the enlargement ratio according to the depth of the hierarchical structure by inserting a special zooming description into a structured document. If this technique is used, the enlargement ratio can be set higher for information considered to have a deep hierarchical structure.

JP 2004-265390 A Japanese Patent Laid-Open No. 2007-4524 JP 2005-115483 A JP 2007-18343 A “About Jig Browser / Jig Browser”, [online], [Search July 24, 2008], Internet http://br.jig.jp/pc/about.html

  If the techniques described in Non-Patent Document 1, Patent Document 3 and Patent Document 4 are used, the display area is limited, and the electronic document can be displayed and controlled in units of blocks even in a state where the entire electronic document is displayed in a reduced size. Only a specific block can be enlarged / reduced.

  However, since the block to be enlarged / reduced and the size of the block are determined in advance, there is no guarantee that the display according to the user's preference is made. For example, even if the user wants to enlarge a certain block in a reduced-size Web page, blocks smaller or larger than expected or all blocks in the same hierarchy are enlarged, so that the user's expectation This is not effective when it is desired to accurately realize the display and when the display area is limited by a small screen terminal or the like. Further, even when a plurality of display modes are provided as in Non-Patent Document 1, some operations such as switching of display modes and designation of an enlarged block must be performed before obtaining a desired display. It is also possible.

  The present invention has been made to solve the above-described problems, and provides an information display system, an information display method, and an information display program that change a layout so that display can be performed in accordance with user preferences. Objective.

  According to the first aspect of the present invention, a dissimilarity with one block selected from the plurality of blocks is calculated based on information included in each of a plurality of regions (blocks) included in the electronic document. There is provided an information display system that includes a dissimilarity calculating unit that generates a layout in which display areas of the plurality of blocks are rearranged according to the dissimilarity and displays an electronic document.

  According to the second aspect of the present invention, the dissimilarity with one block selected from the plurality of blocks is calculated based on information included in each of a plurality of regions (blocks) included in the electronic document. An information display method for displaying an electronic document by creating a layout in which display areas of the plurality of blocks are rearranged according to the dissimilarity is provided.

  According to the third aspect of the present invention, the dissimilarity with one block selected from the plurality of blocks is calculated based on information included in each of a plurality of regions (blocks) included in the electronic document. There is provided a program for causing a computer to execute a process of displaying an electronic document by creating a layout in which display areas of the plurality of blocks are rearranged according to the dissimilarity.

  According to the present invention, it is possible to display information in accordance with user preferences. The reason is that the dissimilarity with one block is calculated based on the information contained in each of multiple areas (blocks), and the layout is created by rearranging each block according to the value. It is in.

[Summary of Invention]
First, the outline of the present invention will be described. The information display system of the present invention selects one block (for example, block 6 of the electronic document in FIG. 3) from among a plurality of areas (hereinafter referred to as blocks) included in the electronic document, and is not connected to other blocks. Similarity or similarity is calculated.

  The dissimilarity or similarity is calculated by visual information such as the layout and color of each block (font color, background color, image tint), image shape, video, dynamic processing, etc. Can be obtained based on elements that can be intuitively recognized by the user.

  Dissimilarity based on elements that can be intuitively recognized by the user, or dissimilarity obtained based on semantic information of blocks such as text content and type (document category) instead of similarity, or Similarity can also be used.

  Furthermore, the dissimilarity (similarity) that takes into account both the dissimilarity (similarity) based on the visual information of the block and the dissimilarity (similarity) based on the semantic information of the block. It can also be used.

  Based on the dissimilarity or similarity calculated as described above, the information display system creates a layout in which the blocks included in the electronic document are rearranged and displays the electronic document (see, for example, FIG. 12).

  For example, for a block whose dissimilarity is greater than a predetermined threshold (not similar, low similarity), the display area is reduced (the enlargement ratio is also reduced), or a non-display layout is created, A relatively large display area is allocated to a block (for example, block 6 in FIG. 12) whose dissimilarity is small (similar, high in similarity) to the selected block (for example, block 5 in FIG. 12). Can be taken.

  In this case, when the setting to display the entire electronic document without scrolling is selected, the occupied area of each block is calculated with respect to the maximum display area of the display or the like, and the display area of each block is calculated. It is desirable to adjust.

[First Embodiment]
Next, a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the information display system according to the first embodiment of the present invention.

  As shown in FIG. 1, the information display system according to the first embodiment of the present invention includes a data processing device 10 that operates under program control, a storage device 11 that stores information, and an output device 12 that displays information. Including.

  Specifically, the information display system as described above is equipped with an OS (Operating System) in a GUI (Graphical User Interface) environment, a storage device such as a memory or a hard disk device, and an output device such as a liquid crystal display unit or a display device. Can be realized by an information processing apparatus such as a personal computer. In addition, since the principle of the present invention is not limited by the type of information processing apparatus and the resolution of the display, it can be realized by a mobile terminal such as a mobile phone terminal or a PDA (Personal Digital Assistant).

  The data processing apparatus 10 includes an input unit 100, a dissimilarity calculation unit 101, a display area setting unit 102, and a display update unit 103.

  The storage device 11 includes a document storage unit 110 and a display environment storage unit 111.

  The input unit 100 is configured by one or a plurality of input devices having a function of passing a user's action situation to the dissimilarity calculation unit 101. For example, when the input unit 100 is a pointing device, information on the block selected by the user is output to the dissimilarity calculation unit 101.

  The dissimilarity calculation unit 101 uses a block acquired from the input unit 100 for visual information or semantic information regarding an electronic document acquired from the document storage unit 110 (hereinafter also simply referred to as “document”). A function of calculating the dissimilarity with other blocks based on the above and outputting it to the display area setting unit 102 is provided.

  For example, when calculating the dissimilarity based on the layout and color which is visual information, the dissimilarity of the block having the same layout as the block selected by the user is set to 0, and conversely, the dissimilarity of the block having a different layout is set. Set similarity high.

  Further, if there are blocks having different colors even if the layout is the same, the dissimilarity is added according to the size of the area. In calculating the dissimilarity, elements that can be intuitively recognized by the user, such as colors, character fonts, image shapes, moving images, or dynamic processing, may be used as visual information.

  Moreover, you may utilize the element which shows the meaning of a block, such as the content and kind (category) of a sentence, as semantic information.

  Note that the dissimilarity calculation unit 101 may automatically select a block according to a predetermined rule without waiting for designation of a reference block from the input unit 100. For example, it is possible to adopt a method in which the dissimilarity calculation unit 101 automatically selects an arbitrary block based on the above-described visual information or semantic information.

  The display area setting unit 102 displays the ratio of the display area given to each block based on the dissimilarity of each block acquired from the dissimilarity calculation unit 101 and the maximum display area acquired from the display environment storage unit 111. A function of calculating the area and outputting it to the display update unit 103 is provided.

  For example, in a document composed of block A, block B, and block C, the dissimilarity with other blocks when the user selects block A is expressed as (A, B, C) = (−, 0, 1). First, a fixed display area is assigned to the block A.

  Next, since the dissimilarity with the block A is 0, the block B is assigned the same display area as the block A. Subsequently, before calculating the display area of the block C, the occupied areas of the block A and the block B are calculated, and it is confirmed whether or not the maximum display area is exceeded. If not, the difference between the occupied area of the block A and the block B from the maximum display area is assigned to the block C as the occupied area of the block C.

  On the contrary, if the occupied area of the block A and the block B exceeds the maximum display area, the occupied area of the block B is changed so as to be within the maximum display area. Assigned to block B.

  The display update unit 103 has a function of rendering an electronic document based on the display area of each block acquired from the display area setting unit 102 and outputting the electronic document to the output device 12.

  The output device 12 outputs to the outside based on the rendering information acquired from the display update unit 103.

  The document storage unit 110 stores an electronic document previously divided into a plurality of blocks. For example, an electronic document (for example, a structured document such as a Web page) is received via a communication network such as the Internet, and a technique such as JP-A-2006-155593 that focuses on document description elements and a hierarchical structure is used. Divide into multiple blocks.

  The display environment storage unit 111 stores a maximum display area, which is a maximum area that can be displayed by the output device 12. For example, if there is a restriction that the scroll is not used, the screen size becomes the maximum display area as it is.

  Next, the operation of this embodiment will be described in detail with reference to the drawings. FIG. 2 is a flowchart showing the operation of the information display system according to the first embodiment of the present invention.

  As shown in FIG. 2, first, the input unit 100 waits for the user to select an arbitrary block, and when selected, passes the information of the block to the dissimilarity calculation unit 101 (step S1).

  Next, the dissimilarity calculation unit 101 acquires information on each block from the document storage unit 110, and based on the block selected by the user acquired from the input unit 100, each dissimilarity is calculated from visual information or semantic information. The dissimilarity with the block is calculated and passed to the display area setting unit 102 (step S2).

  Next, the display area setting unit 102 acquires the maximum display area from the display environment storage unit 111, sets the display area of each block based on the dissimilarity of each block acquired from the dissimilarity calculation unit 101, The data is transferred to the display update unit 103 (step S3). At this time, a layout in which similar blocks are arranged together can be created by setting a display area for each block in ascending order of dissimilarity between the blocks.

  The display update unit 103 renders the document in which the display area acquired from the display area setting unit 102 is set, and passes it to the output device 12 (step S4).

  As described above, according to the present embodiment, blocks that are visually or semantically similar to the block selected by the user are displayed in an enlarged manner, so that it is possible to view content that meets the preference. .

  In the above description, the block that is visually or semantically similar to the block selected by the user has been described as being enlarged and displayed. However, the user's preference is that “similar information is omitted”. If the block is not visually or semantically similar to the block selected by the user (a block whose dissimilarity is larger than a predetermined threshold) is adjacent and enlarged, the similar block (non-blocking) is displayed. It is also possible to perform a modification such as creating a layout in which a block whose similarity is smaller than a predetermined threshold) is reduced or hidden.

  In the above description, the display area setting unit 102 calculates the display area of each block and passes it to the display update unit 103. However, the display area setting unit 102 displays the enlargement ratio and display area occupation ratio of each block. Or the like may be calculated and passed to the display update unit 103. In this case, in determining whether the already allocated area does not exceed the maximum display area, a step of calculating a display area based on the enlargement ratio, the display area occupation ratio, and the like may be added.

[Operation Example 1]
Subsequently, an operation example of the information display system according to the present invention will be described in detail with reference to the drawings. First, a first operation example of the information display system will be described.

  Hereinafter, an example in which a structured document such as a Web page is displayed as an electronic document will be described. The Web page to be displayed may be of any type such as HTML or XML as long as it is created for rendering. However, in the following description, the Web page to be displayed is created in HTML. And

  The data processing apparatus 10 receives a Web page, analyzes the received Web page, and extracts a plurality of blocks.

  Further, the data processing apparatus 10 displays the received web page and waits until the user selects an arbitrary block.

  As described above, a document divided into a plurality of blocks may be acquired in advance, or a block based on a predetermined rule is selected without waiting for the user to select an arbitrary block. As a thing, you may perform the subsequent process.

  FIG. 3 is a diagram showing a layout of a Web page used as a sample. Such a layout can be obtained by analyzing a Web page and extracting a block.

  Hereinafter, as illustrated in FIG. 3, the extracted blocks are referred to as blocks 1 to 8 based on the block extraction order, respectively. Here, it is assumed that the user selects the block 5.

  Next, the data processing device 10 calculates the dissimilarity between the block 5 selected by the user and the other blocks 1 to 4 and blocks 6 to 8 based on visual information or semantic information. Hereinafter, the calculation of the dissimilarity (color) based on visual information and the dissimilarity based on semantic information (type of information) by the data processing apparatus 10, and the dissimilarity as a whole of these will be described. .

  First, calculation of dissimilarity using the type and number of information such as headings and bullets in a block will be described. For example, in the case where there are two blocks A and B as shown in FIG. 4, since there is one heading and there are at least one item in each item, the dissimilarity is 0 from these points. Is calculated.

  On the other hand, the heading color of block A is red, while the heading color of block B is blue and the colors are different from each other, so 1 is added to the dissimilarity. Furthermore, since there is one more item in the block A, 1 is added to the dissimilarity and the dissimilarity is 2.

  Therefore, the dissimilarity between the block A and the block B is calculated as 2. In this example, a method of adding 1 to the dissimilarity every time there is a difference is used for calculating the dissimilarity. However, if the difference between the blocks can be compared, a method other than the above calculation method can be used. Can also be adopted.

  By applying the above calculation method, the dissimilarity between block 5 and block 1 in FIG. 3 is calculated. For example, as shown in FIG. 5, when the block 5 has a heading and a bulleted part and the block has an image and a sentence, the seven elements of the block 5 and the two elements of the block 1 do not match. The dissimilarity at this point is 9.

  Further, since the color of the heading of block 5 is not found in any element of block 1, the dissimilarity is further incremented by 1 to 10. Therefore, the dissimilarity between block 5 and block 1 is calculated as 10.

  Similarly, the dissimilarity between block 5 and block 3 in FIG. 3 is calculated. For example, as shown in FIG. 6, when the block 3 has a heading and a bulleted part, when calculating the dissimilarity between them, the heading and the points 1 to 3 and the bullets 1 to 3 exist in both. 4. Since the bullet item 4 and the image do not exist in the block 5, the dissimilarity is calculated as 3 at this time. Further, since the colors of the bullets 1 to 3 are different from each other, 3 is added to the dissimilarity to be 6. Therefore, the dissimilarity between the block 5 and the block 3 is calculated as 6.

  Similarly, FIG. 7 shows the result of calculating the dissimilarity between the block 5 and the other blocks 2, 4, 6, 7, and 8.

  In addition, you may utilize an information occupation area as a calculation method of dissimilarity. For example, in the case of FIG. 4, since there is no difference in the area between the block A and the block B, the dissimilarity is 0, but since the heading color is different, 1 is added to the dissimilarity. On the other hand, if there is a difference in the areas of the heading portions of block A and block B, points corresponding to the areas are added.

  Information content may be used as a method of calculating the dissimilarity. For example, the degree of dissimilarity may be added according to differences such as the headline being bold, the bullet font being large, or the presence of an image.

  Furthermore, if the block for which the dissimilarity is to be calculated is a structured document, the edit distance obtained from the original source code may be used as the dissimilarity calculation method. FIG. 8 shows an HTML source corresponding to block A and block B in FIG. In this case, the edit distance is the cost of deleting the bullet A2 and is 1. In addition, since the color attribute defining the color is different for each headline, the edit distance is further added to 2. Thus, even if the source code is used, the dissimilarity between the block A and the block B can be calculated as 2.

  The dissimilarity calculation method mentioned above may be used in duplicate. In addition to the above-described calculation methods, anything using visual information or semantic information may be used.

  When the calculation of the dissimilarity of each block is completed as summarized in FIG. 7, the data processing apparatus 10 acquires the maximum display area from the display environment storage unit 111 and the dissimilarity so as not to exceed the maximum display area. The display area is set in ascending order of blocks. In the following example, a display area is allocated from the upper right of the display area.

  Specifically, first, a display area that can be displayed at an enlargement rate that allows the contents to be grasped is set in the block 5 selected by the user (see FIG. 9).

  Note that the display area or enlargement ratio set for the selected block may be automatically calculated and set based on the font size used in the original block, or may be set in advance by the user. May be.

  Next, a display area is set to the block 6 having the smallest dissimilarity with the block 5 (see FIG. 10). In the example of FIG. 10, since the dissimilarity between the block 5 and the block 6 is 0, the display area of the block 6 is set to the same size as the block 5.

  Subsequently, the display area is set to the block 7 having the second lowest dissimilarity after the block 6. At this time, if the display area corresponding to the difference amount 1 of the dissimilarity or the same as the block 6 is set for the block 7, the maximum display area is exceeded in the vertical direction of the screen. The display area given to the block 7 is corrected so as to be within the range (see FIG. 11).

  Similarly, the display areas are set and corrected in the blocks 3 and 4 on the left side of the blocks 5 to 7 in order of decreasing dissimilarity with the block 5 (see FIG. 12).

  Next, when the display area is to be set in the block 1, the maximum display area is used up, so the processing ends here.

  Thereafter, the data processing device 10 performs rendering based on the set display area and displays the result on the display.

  In the above example, the processing is terminated when the maximum display area is used up. However, a display mode of “Allow all blocks to be displayed” is provided, for example, blocks 3 to 3. 7, the display area may not be used up, and the display area may be given to the blocks 1, 2, and 8.

  The preferred embodiments of the present invention and specific examples thereof have been described above, but the present invention is not limited to the above-described embodiments and specific examples thereof, and does not depart from the basic technical idea of the present invention. Then, further modification, replacement, and adjustment can be added.
