This research improves the precision of information extraction from free-form text via the use of cognitive-based approaches to natural language processing (NLP). Cognitive-based approaches are an important, and relatively new, area of research in NLP and search, as well as linguistics. Cognitive approaches enable significant improvements in both…

Discusses an investigation of certain problems concerning the structural design of lexicons used in computational approaches to natural language understanding. Emphasizes three aspects of design: retrieval of relevant portions of lexicals items, storage requirements, and representation of meaning in the lexicon. (Available from ALLC, Dr. Rex Last,…

Presents a system which supports image retrieval by high-level chromatic contents, the sensations that color accordances generate on the observer. Surveys Itten's theory of color semantics and discusses image description and query specification. Presents examples of visual querying. (AEF)

Unlike conventional information retrieval systems, natural language processing (NLP) systems translate queries automatically into the language of the system. This paper discusses the potential impact of NLP on both the indexing and retrieval of text and examines some current NLP projects and systems that have established knowledge bases in narrow…

This paper provides a comprehensive set of guidelines for building an online course based on the e-learning standards. It discusses the steps that should be followed to build a digital repository that facilitates the storage, retrieval, and reuse of the learning resources that comprise an online course in a standard way. The paper also examines…

An examination of the nature of memory reveals that the representation of knowledge cannot be separated from the uses of knowledge. The answering of questions is not a simple retrieval and response of stored information; rather the process is embedded in a general structural framework containing knowledge of the questioner, the question, and the…

Important characteristics of lexical databases and their applications in information retrieval and natural language processing are explained. An ongoing project using various machine-readable sources to build a lexical database is described, and detailed designs of individual entries with examples are included. (Contains 66 references.)

A task required subjects to make a word-nonword decision to visually presented items--words with a high or low number of meanings or lawful nonwords. Words with several meanings produced shorter decision times, indicating that words with multiple meanings have multiple memory entries. (CHK)

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…

THIS PAPER IS THE FIRST IN A SERIES PRESENTING THE FEATURES OF SYSTEMS DESIGNED FOR COMPUTATIONAL LINGUISTICS AT THE LINGUISTICS RESEARCH CENTER (LRC) OF THE UNIVERSITY OF TEXAS AT AUSTIN. ONGOING RESEARCH IS EXPANDING THE APPLICATION OF THESE SYSTEMS TO INCLUDE NOT ONLY NATURAL LANGUAGE BUT PROGRAMING LANGUAGES AS WELL. THIS PAPER DISCUSSES…

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,…

Addresses problems with automated bibliographic and full-text storage of scientific articles. The role of the scientific article is described, the structure is explained, current indexing and information retrieval techniques are criticized, new possibilities using a rhetoric syntax or argumentational syntax are explored, and the use of hypertext…

A relational data system (RDS) is one that has the capability not only to retrieve specific facts but also the ability to deduce facts that are implicit rather than explicit in the data base. The study investigated the application of RDS technology to intelligence data processing. RDS technology and the nature of intelligence data processing are…

Two accomplishments have increased the feasibility of taking preparatory steps for the construction of machine intelligence systems which can acquire knowledge about facts or descriptions of facts through man-machine dialogue in the user's natural language. One is a better understanding of the relationship between perception, language, and…
