Linguistics 575: Lexical Aquisition

Course Info

Instructor Info



Hand-built precision grammars can produce high-quality semantic representations from input strings and generate well-formed strings from input semantic representations. Resources such as the Grammar Matrix can greatly speed up the creation of such precision grammars. However, the expansion of the lexicon remains an important hurdle in scaling up such grammars to practical coverage.

Recent work by members of the DELPH-IN consortium and other research groups has demonstrated the possibility of automatic lexical acquisition from corpora for broad-coverage precision grammars. This seminar will review this work with an eye to how it could be applied in the case of relatively small precision grammars of low-density languages.

Prereqs: Ling 566, 570, and 571 or consent of instructor
