Info-Plaza: A social information filtering system for the World-Wide Web

We have prototyped a social information filtering system based on personal interests. The system is called Info-Plaza and is accessed via the World-Wide Web. Info-Plaza helps people to get new URLs which likely point to interesting web pages. Info-Plaza is a client-server system, which consists of XPlaza and Plaza-Server. XPlaza is a GUI-editor to create and arrange URL-Maps. The URL-Maps are used to register interesting web pages with the server. Plaza-Server has a database of URL-Maps collected from many users. It receives a URL-Map from a user, makes a new URL-Map based on similarities between the URL-Map, and the database entries, and then returns the new URL-Map, to the user. Thus users can exchange interesting URLs through Plaza-Server. Users are expected to edit the returned URL-Map, leaving useful URLs and removing unnecessary URLs. After repeating this process several times, the user will have a URL-Map that contains many links to interesting sites
