Consists of. For example, as shown in FIG. 2, the meta information includes an elapsed time “00:01:00” from the start of distribution (broadcasting) of public content, and a tourist place name “ "Trevi_Fountain" is described. “Trevi_Fountain” is a trevi fountain.

  The meta information is uniquely created by the content provider 10 and is not particularly related to user information stored in a user information storage DB 31 described later.

  As shown in FIG. 1, the general information disclosure site 20 has a general information DB 21, and publishes the general information stored in the general information DB 21 on the Internet. The general information DB 21 is a DB (Data Base) operated at the general information disclosure site 20, and stores general information having a data structure in which a plurality of data are associated with each other.

  The general information stored in the general information DB 21 is LOD (Linked Open Data) described in an RDF (Resource Description Framework) format, and is released in a state where anyone can access it via the Internet. The RDF format is a mechanism for describing a URI (Uniform Resource Identifier) indicating the location of an information resource. In the RDF format, the location of the information resource is described by three sets of a subject, a predicate, and an object. The subject is the information resource to be described, the object is the other information resource, and the predicate indicates the relationship of the information resource. Information resources described in the RDF format are associated with each other, and a LOD that is a huge data space (data set) is generated. In addition, general information is produced | generated based on the data regarding various fields in social life extracted from the data sharing platform scattered on the network which anyone can use, and all specialized fields.

  In the first embodiment, it is assumed that the general information stored in the general information DB 21 includes at least related information of public content. For example, general information stored in the general information DB 21 includes, as related information on public content, information on the outline of a tourist destination name of a travel program and position information (latitude and longitude information) corresponding to the place indicated by the tourist destination name. Are included.

  As shown in FIG. 1, the user information storage site 30 has a user information storage DB 31, and the user information storage DB 31 is widely opened to the public as a storage resource for personal information. It accumulates in the information accumulation DB 31. For example, the user information storage site 30 gives a user ID for identifying an individual to a user who wants to use the user information storage site 30 such as a resident of the user home 200. When personal information is uploaded from the user, the user ID, position information (latitude and longitude information), and personal information related to the position information are associated with each other and stored in the user information storage DB 31. . The location information is implemented, for example, by receiving latitude and longitude information acquired by a GPS (Global Positioning System) receiver mounted on a tablet PC or the like from the user side when uploading personal information. it can.
