Constructing Literature Abstracts by Computer: Techniques and Prospects.
Peer reviewed Peer reviewed
Paice, Chris D. – Information Processing and Management, 1990
Discusses the automatic construction of abstracts from the texts of documents. Automatic sentence extraction is examined, including syntactic criteria and semantic relational criteria; textual cohesion is discussed, including the recognition of anaphors and noun phrases; text structure is addressed; and the concept of abstract-frames is described.…

Toward Relationships-Querying in Document Retrieval Systems.
Peer reviewed Peer reviewed
Rybinski, Henryk; And Others – Information Processing and Management, 1985
Presents a concept of end-user query language with facilities for expressing relationships between objects kept in a database. The idea of nesting these features in typical document query language is shown. Examples of usage of these new facilities are included. (Author/MBR)

Link Indicators and Other Means of Cohesion Indication in Retrieval Languages--Syntactic and Logico-Semantic Properties.
Peer reviewed Peer reviewed
Sechser, Otto – Information Processing and Management, 1982
Analyzes the formal properties, structural consequences, similarities, and differences of link indicators, brackets, and cohesion separators in the query languages employed in information retrieval. Eleven figures, a 32-item reference list, and appendices on Extended Backus Notation and the formal definition of the Formal Relevance Language are…

A Priori Analysis of Natural Language Queries.
Peer reviewed Peer reviewed
Spiegler, Israel; Elata, Smadar – Information Processing and Management, 1988
Presents a model for the a priori analysis of natural language queries which uses an algorithm to transform the query into a logical pattern that is used to determine the answerability of the query. The results of testing by a prototype system implemented in PROLOG are discussed. (20 references) (CLB)

Data as Information.
Peer reviewed Peer reviewed
Dolby, James L. – Information Processing and Management, 1984
Suggests structure based on two sets of principles for deriving meaning from data: Shannon's measure of entropy, which provides means of measuring amount of information in message; and Ranganathan's faceted classification scheme, which provides means of determining number of meaningful data. Syntax, meaning, and semantics of data are discussed.…

Developing a Large Lexical Database for Information Retrieval, Parsing, and Text Generation Systems.
Peer reviewed Peer reviewed
Conlon, Sumali Pin-Ngern; And Others – Information Processing and Management, 1993
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.)
