She has been a member of the Advisory Committee for the DARPA TIDES program, the Chair of SIGLEX, the Chair of SIGHAN, and is now Vice-President of the Association for Computational Linguistics. Her early work on lexically based semantic interpretation formed the basis of the successful DARPA-funded message processing system, Pundit, and fostered a continuing interest in Information Extraction (ACE) and Machine Translation (TIDES). Her interest in lexical semantics and verb classes also led to her involvement in SENSEVAL and the development of English VerbNet and the English, Chinese and Korean Proposition Banks.
