It should be noted that the pasting object creation unit 2-21 with a narrowing condition, the narrowing search condition setting unit 2-22, and the pasting object display unit 2-23 are realized by executing predetermined software in the data processing unit 2-2. It is what.

  The electronic content database 1-2 in FIG. 1 has an identification number (electronic content ID) for uniquely identifying the electronic content so that the pasted object created by the viewer can identify which electronic content is associated with it. Are allocated to electronic content and managed.

  The pasted object created by the viewer is stored and managed in the pasted object database 1-3 in FIG. FIG. 3 is an example of a table configuration of the pasting object database 1-3. The pasted object database 1-3 includes an electronic content ID 3-1, a viewer ID 3-2, a pasted object ID 3-3, a pasted object type 3-4, a pasted object content 3-5, a pasted page / It is a table provided with fields of pasted object position information 3-6 such as row / column, creation date and time 3-7, and narrowing condition setting contents 3-8. The pasting object ID 3-3 is a number used to uniquely identify the pasting object, alone or in combination with the electronic content ID 3-1 and the viewer ID 3-2. The electronic content ID 3-1 is an ID that identifies the electronic content to which the pasted object is pasted, and the viewer ID 3-2 is a viewer ID that identifies the viewer who pasted the pasted object. The pasted object position information 3-6 indicates a position in the electronic content where the pasted object is pasted. Creation date 3-7 is the creation date of the pasted object. Setting details 3-8 of the filtering condition will be described later.

  1 manages an identification number (viewer ID) for identifying the creator of the pasted object.

  Hereinafter, an operation of creating a pasted object in which information on narrowing conditions is set using the system configured as described above will be described.

  4A to 4F show the contents displayed on the display unit 2-1 of the browser terminal 1-5, which are created by the narrowed-down condition-attached pasted object creation unit 2-21. The operations of the browser terminal 1-5 shown in FIGS. 4A to 4F described below are mainly performed by the pasting object creation unit 2-21 with a narrowing condition of the data processing unit 2-2.

  A predetermined operation is performed in advance on the viewer terminal 1-5, and as shown in FIG. 4A, a display target page of the electronic content 4-1-1 is displayed on the display unit 2-1. Shall. A paste object creation button 4-1-2 is displayed on this screen. When the viewer presses the paste object creation button 4-1-2, the screen transitions to a screen as shown in FIG. 4B. Here, the viewer sets to which part of the electronic content the pasted object is to be associated. As a position to be linked, a part 4-2-1 of a sentence, a chart 4-2-2, or a coordinate 4-2-3 can be selected.

  When the position to be linked is selected, the screen transitions to a screen as shown in FIG. 4C. Here, it is assumed that part 4-2-1 of the sentence is selected in FIG. 4B. In FIG. 4C, a screen for inputting contents to be pasted is displayed. Here, the viewer can write a text from the character input field 4-3-1 or select data (image, sound, etc.) to be attached from the file location specification field 4-3-2 as the pasted object. . At this time, the paste object creation unit 2-21 with a narrowing condition determines the type of the paste object by looking at the extension of the attached data.

  When the content of the pasted object is set on the screen as shown in FIG. 4C and the creation button 4-3-3 is pressed, the screen changes as shown in FIG. 4D. Here, the viewer sets a narrowing condition to be set for the pasted object. FIG. 4E shows the details of the sub-screen 44-1-1 for setting the narrowing condition. The narrowing-down condition is composed of one or a plurality of setting items, and when there are a plurality of setting items, it is possible to set a combination of a plurality of conditions. The narrowing condition is like attribute information of the pasted object.

  As a narrowing-down condition, for example, regarding the pasted object, “selection setting of“ spoiler presence / absence ”indicating whether or not the end of the electronic content is touched”, “whether the content is positive for the electronic content “Selection setting of“ content affirmation / denial ”” indicating negative content ”,“ Selection setting of “category” indicating content corresponding to what field ”,“ Direction of content (recruitment of opinions, “Direction” selection setting indicating information provision, indication of error), “Group selection selection setting for allowing pasted objects to be shared only by a specific group”, and the like can be set. It should be noted that the selection condition selection setting may be configured in a plurality of layers. In FIG. 4E, when the upper option 44-2-1 is selected, all items belonging to the lower option 44-2-2 are selected.

  When the narrow-down condition is set and the “OK” button 4-42-3 is pressed, the screen changes to a screen as shown in FIG. 4F, and the created pasted object is transmitted to the host system 1-1 to other viewers. You can select whether to enable browsing or cancel creation. When the “Send paste object to host” button 4-5 is selected, the paste object creation unit 2-21 with a filtering condition creates frame data as shown in FIG. 5 based on the information set above. Then, the data is transmitted to the paste object registration unit 1-7 of the host system 1-1.

  The pasted object registration unit 1-7 separates the received information and registers it in the pasted object database 1-3 as shown in FIG. At this time, information automatically created by the system, such as the registration date of the pasted object, may be registered together so that it can be used as a narrowing condition.

  Next, an operation for narrowing down and displaying pasted objects pasted on electronic contents using the system configured as described above will be described.

  7A and 7B show the contents displayed on the display unit 2-1 of the browser terminal 1-5, which is created by the narrowing search condition setting unit 2-22. The operation of the browser terminal 1-5 shown in FIGS. 7A and 7B described below is mainly performed by the refinement search condition setting unit 2-22 of the data processing unit 2-2.

  By performing a predetermined operation on the browser terminal 1-5, as shown in FIG. 7A, the page of the electronic content 4-1-1 is displayed on the display unit 2-1. In addition, by performing an operation for instructing a predetermined refinement search, a screen for setting a refinement condition used for the search is displayed. FIG. 7B shows details of the sub-screen 7-1-1 for setting the narrowing search condition. The narrowing search conditions that can be selected here include the date and time 7-2-1 when the pasted object was created, the pasted object creator 7-2-2, and the pasted object in addition to the narrowing condition items shown in FIG. 4E. Items other than those set as narrowing conditions by the viewer when creating a pasted object (such as memo text, image, voice, etc.) 7-2-3 (these are also attribute information of the pasted object) Can also be included in the selection options for the refined search condition. Further, when the pasted object is a memo sentence (character information), it is possible to narrow down a part of characters written in the memo sentence from the character input field 7-2-4 and include it in the search condition options.

  A narrow search condition can be specified by combining a plurality of items. When a plurality of items are combined, the condition of each item is interpreted as being connected by AND. For example, in FIG. 7B, if “spoiler” is set to “present” and “positive / negative” is set to “5”, “spoiler” is “present” and “positive / negative” is “5”. ”Will be displayed. In this embodiment, a plurality of items are connected by AND, but they may be interpreted as conditions connected by OR, or the user may select AND / OR.

  When the search condition is set and the “OK” button 7-2-5 is pressed on the screen of FIG. 7B, the search condition setting unit 2-22 creates frame data as shown in FIG. -1 narrowing search processing unit 1-8. The refinement search processing unit 1-8 of the host system 1-1 receives the frame data, searches the pasted object database 1-3 based on the received information, and extracts information from the corresponding record. In the frame data of FIG. 8, the electronic content ID is an ID for specifying the electronic content to be searched (here, the electronic content ID of the electronic content displayed in FIG. 7A), and the narrowed search is performed for the viewer ID. It is assumed that the viewer ID of the viewer who inputs the conditions is set respectively.

  FIG. 9 shows an example in which information corresponding to a given refinement search condition is extracted from the pasted object database 1-3. In addition, although “electronic content ID” is included as a refinement search condition on the lower side of FIG. 9, the electronic content ID is not a refinement search condition explicitly input by the viewer described in FIG. This is information for specifying the target electronic content. Here, since it can be included in the search condition in a broad sense, it was included in the narrowed-down search condition. Based on the pasted object information extracted from the pasted object database 1-3, the narrowing search processing unit 1-8 creates frame data as shown in FIG. 10 and pastes the viewer terminal 1-5. It transmits to the object display part 2-23.

  The pasted object display unit 2-23 displays pasted objects that match the search condition as shown in FIG. 11 based on the received information. The pasting object 11-2 linked to a part of the sentence on the electronic content 11-1 displays an underline 11-3 in the part as a display element for specifying the linked position. The pasted object is displayed by connecting 11-3 with the line 11-4. The pasting object 11-5 associated with the chart on the electronic content 11-1 displays a rectangle 11-6 surrounding the portion as a display element for specifying the chart associated with the electronic content 11-1. The pasted object is displayed by connecting with a line 11-7. The pasting object 11-8 associated with specific coordinates on the electronic content 11-1 displays a point 11-9 as a display element for identifying the associated coordinates, and the line 11 and the point 11-9 are displayed. Connect with -10 to display the pasted object.

  Next, a second embodiment of the present invention will be described. Since the basic configuration is the same as that of the first embodiment, only different parts will be described below. In the second embodiment, as a mechanism for narrowing down and displaying pasted objects pasted to electronic content, a pasted object associated with a location where the viewer pasted the pasted object is displayed. ing. That is, when the second viewer pastes the second pasted object at the location where the first viewer links the first pasted object, the second viewer The first pasted object pasted by one viewer is displayed and can be referred to.

  FIG. 12A shows a case where the second viewer selects a part 12-1 of a sentence and creates a pasted object 12-2 associated therewith. At this time, as shown in FIG. 12B, the pasted object 12-4 that has already been pasted by the first viewer is linked to the location 12-3 that partially overlaps the location 12-1 that is associated. If so, the pasted object 12-4 is displayed as shown.

  In addition, although 2nd Embodiment was demonstrated as what added the said characteristic to 1st Embodiment here, 2nd Embodiment does not necessarily use what uses a narrowing-down condition like 1st Embodiment. It is not a premise. In the case where an object to be pasted is simply pasted on electronic content, if an object already pasted by another person already exists at the position where the user pasted it, it may be displayed. Even with this feature point alone, only the pasted object of the part you are interested in can be displayed, and the pasted object pasted in the part where you are not interested and do not paste the pasted object can be prevented from being displayed. There is an effect that the screen is not complicated. However, it is preferable that the second embodiment is configured in such a manner that a function is added to the one using the narrowing condition as in the first embodiment. In addition to the pasted object that is displayed by searching for the narrowing conditions as in the first embodiment, it is configured as in the second embodiment, so that others are pasting the content that they are interested in. There is an effect that the pasted object is less likely to be overlooked.

  Next, a third embodiment of the present invention will be described. Since the basic configuration is the same as that of the first embodiment, only different parts will be described below. In the third embodiment, the evaluation information of the pasted object is included as the narrowing-down condition of the first embodiment, and the viewer can evaluate the pasted object created by other viewers. .

  As shown in FIG. 13, the evaluation setting units 13-2 and 13-1 are set in the data processing unit 2-2 of the host system 1-1 and the viewer terminal 1-5, respectively. In FIG. 13, the same components as those in FIG. Although not shown in FIG. 13, it is assumed that an electronic content database 1-2, a pasted object database 1-3, and a viewer list database 1-4 are provided as in FIG. Further, an “evaluation information” item 14-1 is added to the pasting object database 1-3 as shown in FIG.

  When the viewer selects one pasted object from pasted objects displayed as shown in FIG. 11, for example, the evaluation setting unit 13-1 of the viewer terminal 1-5 displays a screen as shown in FIG. To do. FIG. 15 shows a state in which the sub-screen 15-1 for selecting the paste object 15-3 and setting the evaluation is displayed. When the viewer sets the evaluation from the sub-screen 15-1 for setting the evaluation and presses the “OK” button 15-2, the evaluation setting unit 13-1 creates frame data as shown in FIG. It transmits to the evaluation setting part 13-2 of the host system 1-1. In the evaluation information in the frame data, the evaluation data selected by the viewer on the above-described sub-screen 15-1 is set.

  As shown in FIG. 17, the evaluation setting unit 13-2 searches the paste object database 1-3 for a record of the corresponding paste object, and updates the evaluation information. In the case of FIG. 17, since the evaluation of “very good” is transmitted, the evaluation of “very good” of the corresponding record is incremented by 1 to 15 to 16.

  If the evaluation information is stored in the pasted object database 1-3 as described above and the conditions for the evaluation information can be specified when performing the narrowing search, the viewer can narrow down the pasted objects. You can use it to display only items with good evaluation.

  In the first to third embodiments, even if the pasted objects are narrowed down and displayed, there may be a plurality of pasted objects that match the conditions. In such a case (for example, when the number of pasted objects searched is greater than or equal to a predetermined number), it may be difficult to see the pasted objects overlapping, so an interface for displaying the pasted objects on the list screen may be prepared. . FIG. 18 shows an example in which a list 18-2 of pasted objects searched by inputting a narrow search condition is displayed on the displayed electronic content page 18-1. A function of rearranging the list in ascending order or descending order of the pasted object creation date and creator may be provided. In addition, by using the evaluation information described in the third embodiment, it is possible to have a function of arranging in order of evaluation.

  Further, in FIG. 18, a list of pasted objects searched by the narrow search condition is displayed. However, without searching, all pasted objects pasted in the currently displayed electronic content are displayed. A list may be displayed. Further, when a pasted object is selected from the displayed list, the pasted object may be displayed in the electronic content.

  Further, in order to display the overlapping pasted objects in a nice manner, in addition to the list screen, as shown in FIG. May be used. In order to realize this, when the pasted object display unit 2-23 creates a table as shown in FIG. 20 in the storage device 2-5 and the frame data of FIG. 10 is returned from the host system 1-1, The viewer ID 10-2 of the frame data, the electronic content ID 10-3, and the position information 10-4-1 of the pasted object are registered in the table. When displaying, it is determined whether there is an overlap in the position where each pasted object is linked, and if there is an overlap, the display element such as an underline indicating each pasted position is displayed with a different color. At the same time, the pasted object is also given a corresponding color and is displayed with a slight shift.

  In addition, it is free to search and browse pasted objects, but there is a charge for registering pasted objects, and to allow viewers to create groups as explained in the filtering criteria example, A billing mechanism may be provided so that a fee is charged for creating a group or joining a group.

As described above, the system according to the present embodiment has the following effects.
(1) Even if a large number of pasted objects are pasted on the electronic content, the viewer can narrow down and display only necessary pasted objects by setting narrowing search conditions based on preferences and the like. .
(2) By giving an evaluation to the pasted object on the electronic content, the viewer can narrow down and display the pasted object based on the evaluation.
(3) Even if a plurality of pasted objects that match the search conditions are overlapped, the pasted objects can be displayed in a list or by being color-shifted so that the necessary pasted objects are not overlooked.
