Abstract : The report summarizes a 9-year study of English morphology, phonetics, syntax, and semantics, and the experiments in automatic indexing and extracting completed. Five main topics are discussed: An algorithm for assigning parts of speech from morphology; an algorithm for automatic syntactic analysis; an experiment in construction of a 'structure dictionary' for extracting purposes; experiments in using frequency and/or syntactic criteria for indexing and extracting purposes; development of word government tables as the basis of a semantic component of an automated text analysis system.
