The growth of indexing services has emphasized the need for more knowledge of the indexing process itself. Consistency is necessary for continuing progress in the field. This study postulates that: (1) definitions of indexer consistency should consist of the indexer's perception of indexable concepts and his choice of terminology; (2) both parts…

This supplementary report was designed to aid the researcher concerned with concept learning. It contains: (1) rationale and strategy for compiling a bibliography of articles concerned with concept learning; (2) a definition of the world "concept"; (3) a system for classifying articles by their content; (4) a bibliography of relevant articles…

Obsessive thoughts (intellectualization, obsessive ideation) were studied by S. Freud, as were compulsions. The former are related to isolation, fixed ideas, compartmentalization, and encapsulation but differ from intellectuality. Compulsions are related to obsessive acts, ritualizations, and undoing but differ from habit. Analagously, obsessive…

A method of preparing computerized subject and author indexes for research and development laboratory notebooks is described. Wiswesser Line Notation is used as the subject entry capable of listing specifically and unambiguously the compounds described in the notebooks. (Author)

The activities of the Dag Hammarskjold Library at United Nations (UN) Headquarters relating to the documentation of the UN are described. The topics discussed are: acquisition and maintenance of materials, indexing, reference, microreproduction, depository libraries, standardization, and coordination with agencies in the UN system. (Author)

Describes a method for enhancing the subject index terms of a document with title terms from cited, citing, and cocited documents. Experimental results of this methodology are presented, and responses to criticisms of this strategy are made. (40 references) (CLB)

Describes the uniterm system of coordinate indexing and examines its applicability to the indexing of Arabic literature. Unresolved problems in semantics, thesauri development, and standardization are identified and discussed. (CLB)

Explains a new methodology for thesaurus design that is specifically geared for use by novice end-users, and describes a faceted hierarchical thesaurus organization which provides an economical information retrieval system in a corporate setting. (Author/LRW)

This study surveyed abstracting policies and guidelines used by producers of bibliographic databases that aim to enhance free-text retrieval. Results indicate editors consider content of abstracts and their language as primary factors in retrieval enhancement. Most recommend that concepts and form be coordinated with controlled vocabulary…

Proposes split model for index term distribution in document set that uses rank function for high frequency terms and size function for low frequency terms; the point of transition is determined either empirically or by rule. Distributions to describe index term exhaustivity and term co-occurrence are considered briefly. (36 references) (EJS)

Study of state of source indexing (indexing data published simultaneously with articles they represent) examines aspects of 685 science journals: science fields using source indexing; source indexing formats; assignment of indexing terms from controlled vocabularies; suppliers of indexing (authors, editors, indexers); use of source indexing by…

Empirical significance of document partitions is investigated as a function of index term-weight and similarity thresholds. Results show the same empirically preferred partitions can be detected by two independent strategies: an analysis of cluster-based retrieval analysis and an analysis of regularities in the underlying structure of the document…

Describes research designed to improve automatic pre-coordinate term indexing by applying language analysis techniques to identify term sources in requests, and to generate variant expressions of concepts involved for document text searching. Text analysis, term extraction, variant generation, and retrieval trial are highlighted. Thirteen…

This volume is a compilation of the papers presented at the 10th ASIS (American Society for Information Science) workshop on classification research. Major themes include the social and cultural informatics of classification and coding systems, subject access and indexing theory, genre analysis and the agency of documents in the ordering of…

Substantial alterations to a system often have little or no effect on particular collections. This may be due to poor separation of relevant and non-relevant documents. The paper presents a procedure for characterizing this separation, which can show whether proposed modifications of the base system are likely to be useful. (8 references)…
