A discussion of the theory and process of indexing--taxonomy, word frequency, and interrelationships of terms. (LS)

Reviews the state of the art in automatic indexing, concentrating on the literature from 1968 to 1973. (Author/PF)

Proposes a new rule system and notation that supports the characterization of a document based on its structure or architecture (primarily linear, paper-copy media). Examples of the application of the notation are provided. (Author/JKP)

Methods of automatically generating controlled subject headings and classifications from free indexing in the INSPEC data base were evaluated. (PF)

Describes a microcomputer-based string index format generated from concept networks using multiple search terms. Link weighting is highlighted as a method to decide which term appears first so the entry reflects the classification implied by the search specification. The computer software used for this system is briefly described. (Author/LRW)

The development of the INSPEC vocabulary system which comprises a unified indexing and classification scheme is described together with the reasons for its adoption. (Author)

Reports the results of experiments using colon classification for the analysis, representation, and retrieval of primary information from the full text of documents. Recall, precision, and search length measures indicate colon classification did not perform significantly better than Boolean or simple word occurrence systems. Thirteen references…

Presents adaptation of a probabilistic theoretical model previously used in relevance feedback for use in automatic indexing of documents (in the sense of imitating) human indexers. Methods for model application are proposed, independence assumptions used in the model are interpreted, and the probability of a dependence model is discussed.…

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)…

Outlines a cognitive process model of abstracting, indexing, and classification that is based on text comprehension processes. Text comprehension for indexing versus other purposes is discussed, including conceptual and perceptual processing; conceptual knowledge and the development of expertise are discussed; and characteristics of short-term and…

Indexing is the preprocessing of information to enable its retrieval, ranging from classification-based (precoordinate) to keyword searching (postcoordinate) approaches. This article describes a framework for modelling information retrieval systems in terms of sets of objects, relationships, and functions and discusses the application of indexing…

Reviews previous work on producing knowledge by the use of information retrieval or classification schemes, and describes techniques by which hidden knowledge may be retrieved, i.e., serendipity in browsing and use of appropriate search strategies. Possible future methods based on relational indexing or artificial intelligence are also explored.…

Symbols for bibliometric concepts like "half life,""impact factor,""normalized impact factor," and "immediacy index" are proposed and formulas for the determination of their values are provided. The features of the bibliometric concepts are also highlighted. (Author/AEF)

Describes the development and evaluation of a new classification system for fiction which is based on an analysis of users' formulations of needs. Problems of concept identification (author's intention, citation order, vocabulary control, and choice of access terms) are highlighted. Examples of questions used in retrieval tests and 20 references…
