For several years now I have been concerned with how artificial intelligence is going to build the substitute for human world knowledge needed in performing the task of text understanding. I continue to believe that the bulk of this knowledge will have to be derived from existing machine-readable texts produced as a byproduct of computer typesetting and(More)
A lexical knowledge base is a repository of computational information about concepts intended to be generally useful in many application areas including computational linguistics, artificial intelligence, and information science. It contains information derived from machine-readable dictionaries, the full text of reference books, the results of statistical(More)
The definition texts of a machine-readable pocket dictionary were analyzed to determine the disambiguated word sense of the kernel terms of each word sense being defined. The resultant sets of word pairs of defined and defining words were then computaCionally connected into t~o taxonomic semi-lattices ("tangled hierarchies") representing some 24,000 noun(More)
This paper discusses the problem of providing natural language access to textual material. We are developing a system that relates a request in English to specific passages in a document on the basis of correspondences between the logical representations of the information in the request and in the passages. In addition, we are developing procedures for(More)
This paper documents research toward building a complete lexicon containing all the words found in general newspaper text. It is intended to provide the reader with an understanding of the inherent limitations of existing vocabulary collection methods and the need for greater attention to multi-word phrases as the building blocks of text. Additionally,(More)
Computational lexicology may be defined as the application of computers to the study of the lexicon. Taken in its broadest sense, it would be a multidisciplinary field involving the analysis of man-made dictionaries using computers to study their machine-readable text as well as a study of the computational linguistic content and organization of lexicons(More)
