  Then, the filter processing unit 140 updates the filter information in the filter information storage unit 130 based on the filter information (step S407), and the annotation processing unit 120 sets the display state based on the updated filter information (step S408). The browser 11 displays the annotation (step S409).

  In this way, the playback unit 160 of the annotation use program 100 receives playback conditions from the user, creates playback instruction information and transmits it to the server 40, and the playback processing unit 250 of the annotation use server program 200 sets the playback conditions as playback conditions. An annotation use system can be used asynchronously by generating annotation information and filter information based on this and sending it to the client who has made a reproduction request.

  As an asynchronous application, there is an application to a document system such as adding a comment to a document using an annotation. By using the annotation utilization system according to this embodiment as a document system, filter information, profile information, etc. It is possible to realize a document system that can change a comment to be displayed according to a user's situation by using.

  Next, an application example of the annotation use system according to the present embodiment will be described. Although the case where the annotation use system according to the present embodiment is applied to education has been described with reference to FIG. 1, the annotation use system according to the present embodiment can also be applied to other fields.

  FIG. 18 is a diagram illustrating an application example (1) of the annotation use system according to the present embodiment to another field. This figure shows a case where a plurality of users share meeting minutes using a Web page. Specifically, “Citizen A1” and “Citizen A2” belonging to Citizen Group A share questions and comments using annotations on the meeting minutes. In addition, “Citizen B” adds a question to the meeting minutes using annotations, and “Citizen C” adds a comment to the meeting minutes using annotations.

  In such a situation, the “manager D1” can see only the question by setting a filter that is conditional on displaying the annotation related to the question. In addition, the “manager D2” can see only the questions and comments regarding the citizen group A by setting a filter on condition that the annotation of the citizen group A is displayed.

  FIG. 19 is a diagram illustrating an application example (2) of the annotation use system according to the present embodiment to another field. This figure shows a case where users at a plurality of bases share information, and various bases such as temperature sensors are installed at each base. In such a case, the display of annotations at each site can be changed according to the status of the site detected by the sensor. For example, it is possible to change the display between day and night by detecting the brightness of the base with an optical sensor.

  That is, information related to the detection result of the optical sensor is added as meta information to the annotation, and information related to the detection result of the optical sensor is set as condition information by the change filter. Then, by generating XML format attribute information from the detection result of the optical sensor and using it as profile information of each site, the display at each site can be changed between day and night. In this way, information from sensors or information generated by other systems can be stored in an external medium or the like in XML format, and such information can be read out from the external medium or the like to dynamically change the display of annotations. .

  As another application example, by retrieving an annotation using an attribute value added as meta information to the annotation as a key, only a specific web page is reproduced from web pages shared in a certain annotation use session. Can be used. For example, in a remote conference, while discussing on the basis of Web content materials, for important matters, the importance “high” is set in the meta information of the annotation, and after the conference, the importance “high” is the key. By narrowing down the search, it is possible to create a digest version of the conference, which can be used by those who are absent, mid-participants, and absent from the conference later to grasp the summary of the conference.

  Next, a computer (client) that executes the annotation use program 100 according to the present embodiment will be described. Here, a computer that executes the annotation use program 100 according to the present embodiment will be described, but the annotation use server program 200 according to the present embodiment can also be executed by a computer having the same configuration.
