Study comparing statistical use in 99 journals from four subject areas (library and information science [LIS], education, social work, business) found that: LIS produced more articles making no use of statistics; and only in LIS were there more articles using only descriptive techniques than articles using inferential techniques. (17 references)…

Discusses the relationship between information science research and practice and briefly describes current research on 10 topics in information retrieval literature: vector processing retrieval strategy, probabilistic retrieval models, inverted file procedures, relevance feedback, Boolean query formulations, front-end procedures, citation…

Reviews citation analysis literature and explores use of citation analysis to identify core journals and indicate disciplinary structure and interrelationships of journals reporting on reading research. Use of 1980 "Journal Citation Reports" data to generate criterion for selecting high impact journals and list of 33 core journals is…

This article adopts "citation approach" to distinguish interdisciplinary or multidisciplinary research (IDR) from monodisciplinary research and begins to descrie how IDR differs from other research. Ten-year citation histories were constructed for sample of 1981 "citation classics" (over-cited articles) and examined for…

Describes experiments relating information to decision making. The experiments were developed to validate previously suggested conceptual model of information flow and its relation to decision making and to establish specific values for significant parameters involved. Background and summary of recent research and experimental design and research…

Describes design and development of a thesaurus based on lexical-semantic relations, and compares results of experiments with queries enhanced using thesauri based on several different groups of relations against performance with original queries run on IRS information retrieval system developed at Illinois Institute of Technology. Twenty-one…

Relations on a finite set V are viewed as weighted graphs. Using the language of graph theory, two methods of partitioning V are examined: selecting threshold values and applying them to a maximal weighted spanning forest, and using a parametric linear program to obtain a most adhesive partition.

Argues that library book circulation is a binomial rather than a Poisson process, and that individual book popularities are continuous beta distributions. Three examples demonstrate the superiority of beta over negative binomial distribution, and it is suggested that a bivariate-binomial process would be helpful in predicting future book…

Analyzes changing information values of journal article titles (measured by counting total number of words, number of keywords, and computing proportion of substantive words). Use of linear regression to determine change patterns for sample of titles from four selected journals, six library journals, and six miscellaneous journals (1951-1980) is…

The Generalized Inverse Gaussian-Poisson Distribution is suggested as an all-embracing mathematical model for bibliometric frequency distributions. Twelve examples are given which show that the new model cannot be rejected by virtue of an objective chi-squared test. A mathematical appendix and 20 references are included. (Author/EJS)

Presents perspectives on methodological assumptions underlying research efforts in artificial intelligence (AI) and charts activities, motivations, methods, and current status of research in each of the major AI subareas: natural language understanding; computer vision; expert systems; search, problem solving, planning; theorem proving and logic…

To test validity of cocitation studies as representations of intellectual structure, five-six years of aggregate cocitation data for 41 authors in macroeconomics and 49 authors in genetics of fruit flies were compared with independent judgments of interauthor similarity collected from 14 macroeconomists and 15 geneticists via a card-sorting…

Data from national survey of researchers, practitioners, and policymakers in rural mental health services were used to conduct sociometric analysis of person-to-person communication. Structure of person-to-person communication network in terms of its connectedness, centrality, homogeneity, and differentiation is described, and strategies for…

Findings of empirical examination of author productivity data to determine conformity to Lotka's law indicate that: most data didn't fit inverse square function; two constants in Lotka's formulation (slope n, constant c) must be derived from observed distribution; inverse square law was special case of inverse exponential relationship. (37…

Group of 20 scholars attributed 29.3 percent of 437 references they had cited to one of seven motives, while describing motives for majority (70.7 percent) of references as combinations. Clustering of citer motives showed three groupings: (1) persuasiveness, positive credit, currency, social consensus; (2) negative credit; (3) reader alert,…
