Description

  The present invention relates to a material information display control apparatus and program for safely and simply browsing confidential materials and important materials on an information terminal.

  Information terminals are widely used in business activities, and browsing and processing of confidential materials and important materials on a display unit (display) of information terminals is also performed on a daily basis. For this reason, in the information display of information terminals on which confidential materials and important materials are displayed, a measure for preventing peeping from others is indispensable.

  As a conventional technique for preventing peeping, there is a technique for performing processing so that a confidential information portion on a display cannot be read and browsing only a portion designated by a user. For example, in Patent Document 1, it is difficult to guess or grasp the text from others other than the user by making only some characters designated by a specific window visible and concealing other characters. . For example, in Patent Document 2, a key word is concealed on a game hint presentation screen, and the concealed word is displayed by a user specifying it with a touch operation.

  By the way, in general, users understand more by understanding and reading the relationship between sentences and sentences and the relation between figures and sentences in order to understand the contents of documents and other materials (for example, figures). It becomes easy to do. For example, if the A sentence and the B sentence are conflicting sentences, they are read while comparing them, and if the C figure and the D sentence explaining it are often read simultaneously.

  However, in Patent Document 1 and Patent Document 2 described above, only the portion designated by the user can be browsed to prevent the peeping action.

  For this reason, it is not possible to browse while comparing the sentence of the designated part with the sentence of another part, or to simultaneously view the figure of the designated part and the explanatory text of the figure.

Embodiments of the present invention will be described below with reference to the drawings showing examples.
FIG. 1 is a system configuration diagram schematically showing an embodiment to which the present invention is applied.
The entire system to which the present invention is applied is connected to a host processing device 13 having the target material 11 as input information, a material information relevance database 12 managed by the host processing device 13, and the host processing device 13 for information transmission. Possible information terminal 14. The host processing device 13 serves as a display control device that controls display of a screen on the display of the information terminal 14.

  The target material 11 is an actual material to be viewed while being concealed at least partially by the information terminal 14. For example, it is assumed confidential materials or important materials that contain information that should not be seen by others, such as personal information, personnel evaluation, and sales information. The formal content of the target material 11 includes sentences and figures, tables, graphs, etc. (hereinafter referred to as “figure etc.”) other than sentences. By reading the target material 11 with an OCR device or the like, the text and diagrams constituting the target material 11 are converted to electronic data and referred to as “material information”.

  The information terminal 14 is operated by the user. The information terminal 14 functions as an information input terminal for the host processing device 13 and a result display terminal for the user. For example, a personal computer display and a mouse, a tablet terminal, or a smartphone touch display is assumed.

  The host processing device 13 includes a material information processing unit 131, a DB registration processing unit 132, a display partial processing screen 133, and a DB search processing unit 134. The functions of these processing units are realized by, for example, reading a program installed in the host processing device 13 that is a server computer into a memory and executing it by the CPU.

  The material information processing unit 131 performs a predetermined preprocessing on the material information of the target material 11 to derive the relevance between each of the plurality of parts in the material information. The DB registration processing unit 132 registers the relevance information in the material information that is the result of the preprocessing in the material information relevance database 12. The display part processing unit 133 receives a display request from the information terminal 14 and performs a process of creating a screen (including a part subjected to the concealment process and a display part from which the concealment process is released) to be displayed on the display. The DB search processing unit 134 specifies the relevant part from the material information relevance database 12 based on the designated part designated from the information terminal 14 in order to identify the display part necessary for the processing by the display part processing part 133. Perform the extraction process.

FIG. 2 is a diagram illustrating an example of a table configuration of the material information relevance database 12.
Each time a new target material 11 is registered in the host processing apparatus 13 shown in FIG. 1, preprocessing is performed by the material information processing unit 131, and the result is registered in the material information relevance database 12.

  The material information of the target material is divided into a plurality of portions for each meaningful sentence or figure by the process of FIG. 3 described later. For each of the plurality of parts, the material information relevance database 12 registers the part and one or a plurality of related parts highly related to the part in association with each other. In the example shown in the drawing, one table is composed of area data of “target material name” 21, “designated part” 22, and “related part” 23.

  The “target material name” 21 stores the name of the target material. The “designated part” 22 is a part which is a main body for obtaining the degree of association (a part designated by the user of the information terminal at the time of use), and information for uniquely identifying the part is registered. The “related part” 23 is a part whose degree of association with the “designated part” 22 is equal to or higher than a predetermined reference value (that is, a highly relevant part), and information for uniquely identifying the part is registered. In the illustrated example, there is one “related portion” 23, but there may be a plurality of “related portions” 23.

  In the example shown in the drawing, each table is created with each of the plurality of portions included in the material information as “designated portions”. In the “designated part” 22 and the “related part” 23, position information of each part in the target material (equivalent to position information on the screen displayed on the display) is registered. In the example shown in the drawing, coordinates having the origin (0, 0) at the upper left of the target material are used as the position information. That is, information that combines the upper left position information and the lower right position information of the range (in this case, a rectangle) occupied by each of the “designated portion” 22 or the “related portion” 23 is used as the position information.

  In some cases, all of the plurality of parts included in the material information may be “designated parts” and the “related parts” may not be obtained. For example, it may be sufficient to obtain and register the “related portion” as only a relatively important portion as the “designated portion”. For example, when the target material is created according to a prescribed format and the important part and the other part are known. Therefore, the pre-processing for obtaining the related portion of the designated portion may be performed for one or more necessary portions (including all cases) among a plurality of portions included in the material information.

  FIG. 3 is a flowchart showing an outline of preprocessing for the target material 11 in the material information processing unit 131 of the host processing apparatus 13 shown in FIG. In the description of the flowchart, the reference numerals in FIG. 1 may be referred to.

  The material information processing unit 131 performs preprocessing prior to use of the system. Using the material information of the target material 11 as input information, the degree of association between each part in the material information is calculated, and the degree of relevance between one part and each other part is calculated based on the magnitude of the calculated degree of association. Judge the degree. Here, the group of portions determined to be highly relevant will be simultaneously displayed after the concealment process is canceled when a predetermined display request is received from the information terminal at the time of use.

First, using the OCR device, texts and diagrams constituting the target material 11 are read to obtain material information (step 31).
Next, based on the read material information, a sentence, a figure, or the like included in the material information is divided into semantic groups by using a paragraph or a sentence as a unit or a figure as a unit (step 32).

  Here, FIG. 4 is an image diagram of the target material 41 before the division processing and the target material 42 after the division processing. The target material 42 after the division processing is divided for each portion 43 that is a semantic group. At the same time, the range occupied by each portion 43, that is, the range occupied on the screen when displayed on the display is determined.

  Next, the degree of association between the parts is obtained based on a predetermined condition regarding the contents of the divided parts. For example, in the case of between sentences, the determination is made based on the co-occurrence of words and the presence or absence of important keywords. Further, for example, in the case of between a sentence and a figure, the determination is made based on whether or not a title such as a figure is included in the sentence. The degree of association is preferably represented by a numerical value or an index equivalent to the numerical value in order to facilitate the comparison of magnitude. When the degree of association between two parts is obtained based on a plurality of conditions, the degree of association between the two parts is obtained by integrating the degree of association according to each condition. In this way, the degree of association with each other part is calculated for one part (step 33).

  Next, it is determined whether or not the calculated degree of association is greater than or equal to a predetermined reference value. One or more other parts having a degree of relevance greater than or equal to a predetermined reference value are specified as a related part for the one part. The predetermined reference value depends on the content of each target material, and is thus determined as appropriate. In this way, the same processing is performed for each part (step 34). The obtained result is registered in the material information relevance database as described above with reference to FIG.

  FIG. 5 is a flowchart showing an outline of processing when the display request processing unit 133 and the DB search processing unit 134 of the host processing apparatus 13 shown in FIG. . In the description of the flowchart, the reference numerals in FIG. 1 may be referred to.

First, the display part processing unit 133 performs a concealment process on all of the divided parts so that the target material 11 cannot be viewed (step 51). In this way, at first, a screen is created in which all parts of the target material 11 are concealed.
Next, a request for displaying material information specifying a portion for which the concealment process is to be canceled is received from the information terminal 14 (step 52).

  Here, the left side of FIG. 6 is an image diagram of a screen 61 first displayed on the display of the information terminal 14. Initially, all parts are hidden and displayed. When the user designates one part to be displayed as the designated part using the designated cursor 62, information on the designated part is transmitted to the host processing device 13.

  Next, the DB search processing unit 134 searches the material information relevance database 12 based on the designation of the designated part included in the display request received from the information terminal 14, thereby identifying the corresponding designated part and the designated part. One or a plurality of related parts associated with each other are extracted. These extracted designated parts and related parts are specified as display parts in the material information. And the sentence or figure of the specified display part is acquired (step 53).

Next, after the concealment process of the display part (designated part and related part) is canceled, the screen of the target material 11 is created (step 54).
Here, the right side of FIG. 6 is an image diagram of a screen displayed on the display of the information terminal 14 after the concealment process of the designated portion 63 and the related portion 64 is released. The display part from which the concealment process is released can be browsed.

  Further, the display part processing unit 133 determines whether or not the designated part has been changed from the mobile terminal 14. When the change has been made, the process returns to step 51 to conceal the displayable part again and wait for the input of a new designated part from the portable terminal 14 (step 55).
