Work on the first component of the Linguistic Research System, a general language data processing system, is described. This normalization component analyzes sentences in natural language and assigns to each sentence its semantic reading or readings. Further, it reduces to one representation paraphrases of sentences which result from syntactic transformations, substitution of synonyms with identical parts of speech, substitution of synonyms with different parts of speech, and substitution of terms of length one by synonymous lexical collocations. The normalization component processes text in natural language by means of a subscript grammar, a system of rule schemata which permits the recognition algorithms to construct context-free grammar rules.
