Research Topic


Status

The IntFilter project is now closed. The project built a fully operational prototype of a filtering news reader (Pefna). The reader was tested both in its ability to classify news and in actual operation by three users.

Some of findings of the project were:

Choices in the Implementation of Rating

This paper discusses some options for the design of a rating (=social filtering) system for internet objects. An architecture for a rating and filtering system is also presented. This architecture is designed to allow different groups to develop different modules in the rating and filtering system.

GHOSTS

The Ghosts systems was a first prototype designed for the newsreader nn. It was based on an editor for boolean rules and a production engine. The work on Ghosts was stopped august 1994 and it never really came into full-scale use.
