TOPIC:        Ontologies for Machine Translation -
              Or how to build a principled interlingua
                 (if such a thing exists)

SPEAKER:     Dr. Eduard H. Hovy, Information Sciences Institute
             of the University of Southern California.

DATE:        Wednesday, 17 April 1996

TIME:        7:30 PM

PLACE:       Loyola Marymount University, Pereira Hall 51.
             (LMU is located on Loyola Blvd. at 80th Street in
             Westchester.  From the 405 Fwy, take the H. Hughes
             Parkway exit, then: south on Sepulveda about 1/4 mile
             to 80th Street, west about 1 mile to Loyola Blvd., north
             to enter campus, ask guard for directions to Pereira Hall.
             Parking is free, but might take a minute or two to find.)

ABSTRACT:    In the past year or two, the availability within AI of several
             large-scale taxonomies (often called Ontologies) has generated
             considerable interest, mostly for how they can be used to speed up
             the construction and enhance the robustness of knowledge-based AI
             systems. At ISI, we have built a concept taxonomy (the Pangloss
             Ontology) that contains approx. 70,000 nodes and is linked to 
             lexicons of English, Spanish, Japanese, (and soon, Arabic)   
             words. It is used in several Machine Translation systems. This  
             talk describes an asymptotic and incremental approach toward true 
             language-independence grounded in practical concerns (such as 
             what a Machine Translation system requires in order to function).

BIOGRAPHY:   Dr. EDUARD HOVY leads the natural language project at ISI,
             a project conducting research in Machine Translation, natural  
             language text planning and generation, the construction of large 
             knowledge bases and lexicons, automated topic extraction and 
             summarization, medical informatics, and multimedia presentation 
             planning. Dr. Hove, who received a Ph.D. in Computer Science from
             Yale University in 1987, is Vice President of the Association of
             Machine Translation in the Americas (AMTA), serves on the 
             Executive Board of the Association for Computational Linguistics 
             (ACL), and has served on the editorial board of 
             Computational Linguistics.

DINNER:      No dinner or social activities are planned.
