This paper describes how the problem of resolution of syntactic ambiguities is approached in the parser PHRASE, developed for use in experiments in automatic indexing and extracting. PHRASE is a multi-level parser for declarative sentences, in which the syntactic structure is built up in four stages. (10 references) (Author)

The strategy for PASP proposed here is characterized by the: (1) ad hoc nature of some of its parts; (2) use of a linear string grammar, (3) definition of probability rules, (4) translation of those rules into a priori rules for the string grammar, (5) context sensitivity, and (6) flexibility of the system.

This report describes an optimization phase of the SYSTRAN (System Translation) machine translation technique. The most distinctive characteristic of SYSTRAN is the absence of pre-editing; the program reads tapes containing raw and unedited Russian texts, carries out dictionary and table lookups, performs all syntactic analysis procedures, and…

A COMPUTER PROCEDURE IS DESCRIBED FOR PARSING RUSSIAN SENTENCES WITH A CONTEXT-FREE RECOGNITION GRAMMAR. THIS IS THE FIRST PROJECT UNDER A PROGRAM FOR THE INVESTIGATION OF SEVERAL ASPECTS OF NATURAL LANGUAGE DATA PROCESSING BY FORMALIZED METHODS TO DETERMINE THE USEFULNESS OF FORMALIZED LINGUISTIC TECHNIQUES IN PRACTICAL LANGUAGE DATA PROCESSING…

The report describes the Classroom Information and Computing Service (CLICS), a pedagogical computer-based information system that is used as a case study in the subject "Information Systems" in the Dept. of Electrical Engineering at M.I.T. CLICS is an abstraction of the Multiplexed Information and Computing Service (MULTICS) that is being…
