Extending thematic lexical resources by term categorization

Researchers from IEI-CNR, Pisa, and ITC-irst, Trento, are currently working on the automated construction of specialized lexicons1, as part of an ongoing collaboration in the fields of Machine Learning and Information Retrieval. Increasing attention is being given to the generation of thematic lexicons1 (ie sets of specialized terms, pertaining to a given theme or discipline). Such lexicons1 are useful in a variety of tasks in the natural language processing and information access fields, including supporting information retrieval applications in the context of thematic, 'vertical' portals.
