Topics to be considered include the components Syntactic frameworks currently under development in linguis- of natural language processing system; syntax analysis tics take different perspectives on several issues of computa- tional interest. Among these are: (1) the importance of stat- (including context-free grammars, augmented context-free ing linguistic theories in well-defined and explicit formalism grammars, grammatical constraints, and sources of syntactic whose mathematical properties are known or investigable; (2) ambiguity); semantic analysis (including meaning represen- tation, semantic constraints, quantifier analysis); and dis- the degree to which the syntatic properties of sentences can course analysis (identifying implicit information, establishing be understood independently of their semantic interpretation; and (3) the extent to which empirical and mathematical text coherence, frames, and scripts).
