Connectionist Treatment of Grammar for Generation: Relying on Emergents.

摘要

Parallel treatment of syntactic considerations in generation promises quality and speed. Parallelism should be used not only for simultaneous processing of several sub-parts of the output but even within single parts. If both types of parallelism are used with incremental generation it becomes unnecessary to build up and manipulate representations of sentence structure the syntactic form of the output can be emergent. FIG is a structured connectionist generator built in this way. Constructions and their constituents are represented in the same network which encodes world knowledge and lexical Knowledge. Grammatical output results from synergy among many constructions simultaneously active at ran-time. FIG incorporates new ways of handling constituency, word order and optional constituents; and simple ways to avoid the problems of instantiation and binding. Syntactic knowledge is expressed in a simple, readable form; this representation straightforwardly defines parts of the network.
