Parsing with constructions and ontology
Wlodek Zadrozny · 1994
We address two themes of the workshop: (A) We argue against the standard design morphology-syntax- semantics-pragmatics. (R) We argue for a close relationship between the knowledge representation language (used for reasoning) and the language for natural language processing. Regarding the first issue, we present a new model of natural language based on the con-cept of consgruclion, consisting of a set of fea-tures of form, a set of semantic and pragmatic conditions describing its application context, and a description of its meaning. A parser based on this model allowed us to build a pro-totype of a natural language system: a front end to an on-line calendar application. With respect to the second issue, we show the advantages of embedding ontology into the grammar. Namely, our hierarchy of np con-structions is based on the corresponding on-tology. We also show how (A) and (R) related. 1
