abstract bibtex

Several machine learning techniques have been applied to the named entity (NE) recognition problem. However, there has been less progress on the problem of identifying relations between them; an important process in Information Extraction. This paper presents an unsupervised algorithm based on WordNet which discovers relations between entities in text, including those which have been identified as NEs. Comparative evaluation with a previously reported approach shows that the algorithm presented here is in some ways preferable and that benefits can be gained from combining the approaches using cotraining.
