Research performed, in part, while the author was a research assistant at the Wisconsin Research and Development Center for Cognitive Learning; remainder conducted at the University of Texas under a National Science Foundation - USDP grant. (VM)

In contrast to conventional information storage and retrieval systems in which a body of knowledge is thought of as an indexed codex of documents to which access is obtained by an appropriately indexed query, this interdisciplinary study aims at an understanding of what is "knowledge" as distinct from a "data file," how this knowledge is acquired,…

Research performed while Shannon Moeser was on a Science Scholarship of the National Research Council (NRC) of Canada, and forms part of this author's doctoral thesis submitted to McGill University. Research also supported by an NRC grant to Mr. Bregman. (VM)

The report documents performance on a 24-month R&D effort oriented toward the development of a computerized model for machine translation of natural languages. The model is built around a set of procedures called verbalization, intended to stimulate the processes employed by a speaker or writer in turning stored information into words.…

Mental activities and information learned in one context are not necessarily available for use in another. They often have to be learned anew in the second context, although perhaps with less time and effort. The fact is, however, that relatively little is known about how the activities of the mind affect one another. The study of bilingualism,…

The author finds Katz and Postal's 1964 generative semantic theories concerning the organization of grammar incorrect and proposes an interpretive approach to semantics in which syntactic structures are given interpretations by an autonomous semantic component. The research reported leads the author to describe a generative grammar consisting of…

This study is designed to help provide an understanding of the role semiosis plays in information processes. The object of study is the structure of various types of signs, and a determination of the relationship between sign structure and information properties. A review of the theory of sign structure is followed by an examination of syntactic…

This paper describes the notation and underlying organization of an augmented, recursive-transition network grammar and illustrates how such a grammar is a natural medium for expressing and explaining a wide variety of facts about the psychological processes of sentence comprehension. A general discussion of transformational grammar and…
