Intelligent Filtering of Computer-Mediated Human Communication
This document serves as the IntFilter project's central repository for
documentation, schedules and other information of not too-volatile
nature. Please send an email to the

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:
- automatic text classification into loosely defined categories is
possible, but much of the final efficiency depends on the selection of
good examples.
- the users were not convinced that the system helped them; their
confidence in the filtering process was undermined by what
appeared to be blatant misclassfications.

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.
