Levels of representation in natural language based information systems and their relation to the methodology of computational linguistics
Gisela Zifonun · 1980
In this paper the methodological basis of the 'computational linguistics approach' for representing the meaning of natural language sentences is investigated.Its adherance to principles of formal linguistics and formal philosophy of language like the 'separation of levels of syntactic and semantic analysis', and the "Fregean" principle may be contrasted with the 'artificial intelligence approach'.A "Montague" style method of mapping the syntax of natural language onto the syntax of the 'semantic language' used as the means of internal representation in the information system PLIDIS is presented.Rules for defining subsequent levels of representation like 'syntax-interpretative level', 'redundancy' free level' are given.
