The inverted index is the main data structure used by all the major search engines. Search engines build an inverted index on their collection to speed up query processing. As the size of the web grows, the length of the inverted list structures, which can easily grow to hundreds of MBs or even GBs for common terms (roughly linear in the size of…

Veterinary medical research traditionally focuses on animal health and wellness; however, research activities at veterinary colleges extend beyond these traditional areas. In this study, we analyzed eleven years of Web of Knowledge-indexed peer-reviewed articles from researchers at the twenty-eight United States American Veterinary Medical…

The article presents 30-year bibliometrical results on trends in the scope, internationality, and impact of the "International Journal of Behavioral Development" ("IJBD") from its inception in 1978 to 2007. Bibliometric data were collected using the databases PsycINFO and Social Science Citation Index (SSCI), and the "IJBD" itself. In comparison…

A survey of automatic indexing systems and experiments has been conducted by the Research Information Center and Advisory Service on Information Processing, Information Technology Division, Institute for Applied Technology, National Bureau of Standards. Consideration is first given to indexes compiled by or with the aid of machines, including…

This paper was prepared to provide a frame of reference to the role of microfilm within the information retrieval world and to provide an opportunity for evaluation of the use of microforms for active retrieval applications. The paper discusses the principles of information retrieval, considers subject and classification indexing, and describes…

Problems in indexing library and information science literature occur because of the speed of introduction of new terms, the nature of class headings, and the uncertain terminology of the field. Vocabulary control requires control over the concepts selected (the depth of indexing), the form of expression of concepts and the syndetic apparatus of…

Subjects covered in this bibliography include manual, mechanized and automated techniques, evaluation of systems, standards, storage and retrieval systems, research, vocabularies, author participation, permuted title indexing, citation indexing, and specialized indexing requirements, i.e. chemistry, medicine, patents, engineering drawing, and…

This programmed course consists of four lessons which cover the general principles of indexing, the specific methods of coordinate indexing, and the use of the Educational Resources Information Center (ERIC) Thesaurus. In the first volume the five appendices contain: (1) an index to the major themes of the course, (2) some definitions of form…

The objectives of this research were to investigage (1) the feasibility of an index simulator, and (2) the use of a sequential analysis model for the automatic classification of documents. Index simulation was studied in general for various types of indexes, and in depth for the simulation of an inverted coordinate index to a document collection…

Describes a framework for building "story traces" (compact global views of a narrative) and "story projects" (selections of key elements of a narrative) and their applications in text understanding and classification. The resulting "abstract story traces" provide a compact view of the underlying narrative's key…

Describes the development of a functional indexing system that is tailored to the thinking involved in the process of invention. Classification by function is discussed; matrix representation is explained; a controlled vocabulary of verbs, objects, and modifiers is described; and the relation to other indexing systems is examined. (13 references)…

Demonstrates application to art literature of indexing system which involves conceptual analysis of content and characteristics of documents using descriptors assigned to facets of the discipline and its literature. Indexing vocabulary and syntax, alphabetical and classified indexes, and exhaustivity of indexing are discussed. Sample indexes and…

Deals with the relationship between a theory of indexing and a theory of information storage and retrieval. Attention is directed to the view that indexing is an order increasing operation, and some thermodynamic notions are invoked to aid in this description. (MF)

The investigation is part of a continuing project to find better means for studying and evaluating document representations (e.g., abstracts, indexes). The present study focused on understanding the ways individuals interpret index terms, with the goal of using the findings in improving indexing systems. Indexing systems use all-or-none bases for…
