This overview of the writings of Manfred Kochen focuses on the pervasive theme of the growth, fragmentation, and integration of knowledge. Topics discussed include information science; the problem of fragmentation and specialization in the growth of knowledge; knowledge structures and cognitive science; and the application of Kochen's ideas to…

Presents the theoretical aspects of a data analysis methodology that can help transform sequential raw data from a database into useful information, using the statistical analysis of patents as an example. Topics discussed include relational analysis and a technology watch approach. (Contains 17 references.) (LRW)

Discussion of nonlinear dynamic mechanisms focuses on whether information production and dissemination can be described by similar mechanisms. The exponential versus linear growth of literature is discussed, the time factor is considered, an example using literature from the field of superconductivity is given, and implications for information…

Proposes a new measure of the citation speed of scientific publications based on a stopping time approach. The stochastic process approach in bibliometrics is described, mean response time (MRT) is discussed, harmonic mean response time (HMRT) is explained, and examples are given. (six references) (LRW)

Illustrates that the Poisson-lognormal model provides good fits to a diverse set of distributions commonly studied in bibliometrics and scientometrics. Topics discussed include applications to the empirical data sets related to the laws of Lotka, Bradford, and Zipf; causal processes that could generate lognormal distributions; and implications for…

Presents a method for abstracting scientific documents based on a psychological model of a problem solving process. Each component of problem structured abstracts--document problem, problem solution, testing method, related problems, and content elements--is described. When compared with INSPEC abstracts, problem structured abstracts were shown to…

Discusses the interpretation of nominal compounds in the context of natural language processing for information retrieval. Knowledge-intensive algorithms that can successfully interpret compounds found in technical documents are described, and experiments are reported that indicate these algorithms may be unnecessary for improving retrieval…

Discusses the problems inherent in applying what is learned in a carefully controlled information retrieval (IR) research project to searching the scientific databases available through a large commercial database. STN International is used as an example. (five references) (LAE)

Discusses the use of citation networks for constructing measures of the relative standing of journals in scientific journal-to-journal networks. Topics addressed include eigenvectors; measuring the standing of national scientific communities; and an empirical comparison of two measures of standing, one considering the environment and one without…

Discusses research into chemical information and document retrieval systems at the University of Sheffield. Highlights include the use of cluster analysis methods for document retrieval and drug design, representation and searching of files of generic chemical structures, and the application of parallel computer hardware to information retrieval.…

Discussion of the use of scientific information disseminated in primary subject literature focuses on a study that developed a methodology for hypothesis testing that measured document obsolescence by means of citation analysis and content obsolescence by expert opinions and then compared the results. Information validity and information utility…

Describes an empirical study that was conducted to examine the relationship among scientific co-authorship (i.e., collaboration), research funding, and productivity. Bibliographic records from the MEDLINE database that used the subject heading for schistosomiasis are analyzed, global and local collaborators are discussed, and scientific…

Describes a bibliometric study of the "Nigerian Journal of Microbiology" that was conducted to aid librarians in scientific journal selection decisions. Data are presented on authorship; forms of literature; ages of the literature; ranking of titles included in citations; geographic location of authors; and academic disciplines of…

Describes a study that examined the communication pattern of Croatian scientists in the field of biomedicine related to citing articles in domestic sources. An analysis of references and a survey of authors are used to study differences in scientists' attitudes toward domestic versus international journals. (Contains 13 references.) (LRW)

Outlines procedures for selecting scientific journals for academic library collections and provides a model which ranks data sources according to their relative weights rather than ranking the journals themselves. Use of the model in scientifically less developed countries is discussed. (Author/LRW)
