Abstract: The authors study the extent to which natural
        language processing techniques aid the automatic
        indexing and retrieval of documents. They describe
        the use of signature files in large text retrieval
        systems. They show that good performance can be
        obtained without requiring the significant overheads
        required for the inverted file technique. The use of
        syntactic analysis of the text in all stages of
        retrieval is examined and it is argued that an
        initial Boolean query should be performed that
        provides a subset of documents, which are then
        ranked. An algorithm is given for generating such
        queries, taking into account the syntactic structure
        of the queries
