6. CONCLUSION.
</SectionTitle>
    <Paragraph position="0"> We have outlined a research program intended to provide a comprehensive set of tools and methods for using machine readable dictionaries to produce computerized dictionaries suitable for use in natural language process~ ing systems. We have presented operational tools and analysis results which we have obtained with them. A Computational Linguistics, Volume 13, Numbers 3-4, July-December 1987 239 Roy J. Byrd, Nicoletta Calzolari, Martin S. Chodorow, Judith L. Klavans, Mary S. Neff, Omneya A. Rizk Tools and Methods wide variety of techniques from computer science, linguistics, and lexicography need to be combined in order to succeed at building the dictionaries we envision. The project described here provides a coherent framework and computational basis for proceeding.</Paragraph>
    <Paragraph position="1"> ACKNOWLEDGEMENTS.</Paragraph>
    <Paragraph position="2"> We are grateful to Yael Ravin and Howard Sachar for their major and continuing contributions to the analysis of the Collins Thesaurus. Barbara Kipfer performed significant early analyses of semantic features, using sprouting and filtering. Gustaf Neumann and Seved Andersson added important new functions to the Dictionary Access Method, and Neumann used the new DAM to build WordSmith functions for Webster's Seventh and Longman. We thank the group working on the Italian Machine Readable Dictionary at the Institute for Computational Linguistics in Pisa for ideas conveyed in the present work. We also thank Robert Ingria for suggesting the use of direct nominalizations in the study of active and stative verbs.</Paragraph>
