We focus on the probleln of building large repositories of le.rical coJtceplual structure (LCS) representations for verbs in multi- ple languages. One of the main results of this work is the definition of a rela- t, ion between broad semantic classes and LCS meaniug components. Our acquisi- tion program--LEXICALL--takes, as in- put, the result of previous work on verb classification and thematic grid tagging, and outputs LCS representations for differ- ent. languages. These representations have been ported into English, Arabic and Span- ish lexicons, each containing approximately 9000 verbs. We are currently using these lexicons in an operational foreign language tutoring and machine translation.
