This report comprises two documents which describe the state of the art of computer generation of natural language text. Both were prepared by a panel of individuals who are active in research on text generation. The first document assesses the techniques now available for use in systems design, covering all of the technical methods by which…

A computer natural language system called HWIM (Hear What I Mean) is described in this report. Noting that the system accepts either typed or spoken inputs and produces both typed and spoken responses, the report proposes HWIM as an example of a relatively complete language system illustrating how the many components of language processing…

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…

This report is the third in a series of annual reports describing the research performed by Stanford Research Institute to provide the technology that will allow speech understanding systems to be designed and implemented for a variety of different task domains and environmental constraints. The current work is being carried out cooperatively with…

A Computer-Assisted Language Analysis System (CALAS) was developed as a syntactic and semantic analyzer of machine readable text in English. CALAS includes a set of computer programs, an algorithm for implementation, and human editors who assist the computer and its programmer in the processing of data. Data analysis is accomplished in three…

Noam Chomsky's transformational-generative grammar model may effectively be translated into an equivalent computer model. Phrase-structure rules and transformations are tested as to their validity and ordering by the computer via the process of random lexical substitution. Errors appearing in the grammar are detected and rectified, and formal…

Used a lexical statistics program to analyze conflict and nonconflict discussions of two different groups of college students. Found preliminary evidence for a pattern of greater redundancy and less vocabulary diversity for the discussion groups in conflict. (PD)

This paper describes a system for the computer understanding of English. The system answers questions, executes commands, and accepts information in normal English dialogue. It uses semantic information and context to understand discourse and to disambiguate sentences. It combines a complete syntactic analysis of each sentence with a heuristic…

The system described in this report is designed for use as a computational tool that allows a linguist to develop and study methods for generating surface strings from an underlying semantic structure. Initial findings with regard to form-determiners (such as voice, form, tense, and mood), some rules for embedding sentences, and some attention to…
