Abstract

This paper addresses the problem of Information Extraction (IE) system customization to new domains and extraction needs with the use of PatEdit, an IE Pattern Editor. PatEdit is a human-assisted knowledge engineering tool, that facilitates the production of IE patterns. First, we present the problem of IE system customisation and the use of human assisted knowledge engineering tools. Then, we describe PatEdit with respect to the IE pattern language used and discuss its characteristics that facilitate rapid pattern writing. Finally, the exploitation of PatEdit in two information extraction projects is presented along with our plans for future work
