Deep Case Systems for Language Understanding. Technical Report No. 362.
Noting that the idea of linguistic case has evolved from an account of noun affixes (surface case) to an account of how syntactic relations between noun phrases and sentences map into deep relations between objects and events (deep case), this paper examines the notion of deep case as it applies to natural language understanding. Following a review of work on case grammars, primarily from the perspective of their use in computer natural language understanding systems, the paper discusses the distinction between surface cases and deep cases. It then examines the relation of deep cases to grammatical explanation and representation of meaning. The paper concludes with descriptions of four representational approaches to theories of case structures: (1) deep case relations, (2) case sequence paradigms, (3) discourse analysis, and (4) conceptual cases. Three figures and a four-page reference list are provided. (FL)
