Using an existing parsing program and dictionaries as a starting point, a set of programs for building a bibliographic dictionary automatically from text was generated and then tested on a newswire text. (9 references) (Author)

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)

Computer programs have been written which enable substructure searches to be carried out on a file of compounds ciphered using a modified version of the IUPAC (Dyson) notation. The search system outlined is to be linked with one which uses input from the chemical structure typewriter. (3 references) (Author)

Reports on a series of programs that have been developed to process data bases, consisting of textual items, and to index and arrange (classify) the data items in accordance with an automatically generated classification system. (Author)
