This paper is a survey of some of the major semantic models that have been developed for automated semantic analysis of natural language. Current approaches to semantic analysis and logical interference are based mainly on models of human cognitive processes such as Quillian's semantic memory, Simmon's Protosynthex III and others. All existing…

The first part of this dissertation is a metatheoretical discussion of the needs and means of semantic analysis. This discussion includes sections on metalanguage, deep and surface structure and structural semantics, and procedures for relating the English of abstracts to a classification concordance in the same language. The second part describes…

The relationship between the disciplines of linguistics and information science has not yet been studied in depth. We must assess the state of our knowledge of natural language and determine how this knowledge is applicable within the context of an information system. The concept of a natural language information system can be specified in terms…

The symposium focused on advances in techniques in the computer oriented technology of information retrieval. Early developments and the status of recent efforts in document retrieval, question answering and data management systems are briefly reviewed. Unless fundamental processing techniques are developed and made available to workers,…

The objective of this thesis was to colligate the various strands of research in the literature of computational linguistics that have to do with the computational treatment of semantic content so as to encode it into a computerized dictionary. In chapter 1 the course of mechanical translation (1947-1960) and quantitative linguistics is traced to…

Presents an algorithm for use in natural language document retrieval systems which automatically determines if the conjunction "and" in a statement representing an information need should be translated into a Boolean "and" or "or." The results of an experiment that used the algorithm are reported, and further research is suggested. (CLB)
