2. Description of the Related Art With the spread of communication means such as the Internet and satellite communication in recent years, various information transmission and electronic newspaper distribution services have been performed. Conventionally, a user who browses an electronic article delivered electronically needs to separately perform a keyword search using a keyword indicating the content of an article in order to obtain related article information of a certain article.

In order for the user to browse the related article information, it is necessary for the electronic article sender to perform a work such as linking the related article / related information to the article in advance. With electronic articles such as the electronic newspaper that is added, there is a drawback that the electronic newspaper creation work becomes complicated. In addition, the links to related articles that are configured when creating an electronic article can be applied only to electronic articles that are currently delivered at the same time and electronic articles in the past, and if that electronic article is published later, it will be delayed. There was a problem in that once an electronic article had been delivered, it was not possible to attach a related article link to a new electronic article thereafter.

In the method described in Japanese Patent Laid-Open No. 9-153052, it is necessary to distribute the electronic article itself and the genre of the electronic article, that is, the category, as information, and each individual electronic article has a category representing the genre. It had to be set and embedded, which made the work up to delivery complicated. Furthermore, if one electronic article is given a category of A and another electronic article is given a category of B, it is preferable that both of them belong to the category of C with the passage of time, and the categories of A and B are abolished. In many cases, such as the case described above, the method disclosed in Japanese Patent Laid-Open No. 9-153052 does not allow the user to change the information once it has been embedded in the electronic article, so the related article information that was available at the time is displayed. There was a problem that I could not.
