摘要:

AbstractThe concept of thematic analysis, as developed by Gerald Holton, Robert Merton, and others, is reviewed and characterized. The strengths and limitations of this concept are briefly discussed. The applicability of thematic analysis to information science is explored by means of examining four thematic models of change of state of knowledge, as exemplified by terms such as “literature obsolescence.” Articles from ten years of theJournal of the American Society for Information Science(volumes 16–27) were selected for examination. Several of these articles are shown to have thematic content and to exemplify the four models of change of state of knowledge. A concluding discussion assesses the implication of thematic analysis for information science and points out some unresolved problems of such ana

摘要:

AbstractA replication of Nelson and Mitroff's 1974 experiment in using computer gaming to teach “Bothsides” thinking was conducted in The Netherlands. Their results were not confirmed with regard to the attitude change of participants. The programmed well‐defined problem did not trigger Bothsides thinking, and, in our opinion, does not fit this mode of decision‐making. In addition, we found the list of questions for measuring the “change of mind” of the players neither valid nor reliable. The provisional conclusions of the research reported here are that (1) an ill‐defined rather than a well‐defined problem is needed, (2) the problem should be relevant and realistic, (3) an analysis of the process of thinking while playing the game is a better measure of eventual changes in the mode of thinking of the participants than postgame pencil‐and‐p

摘要:

AbstractInformation system outputs and user needs vary with the phases of the innovation decision‐making process as defined by Rogers and Shoemaker: awareness/knowledge, attitude formation/persuasion, trial/decision, confirmation. Within each phase, products and user needs can be defined as the parameters of user characteristics, subject content, packaging characteristics, and marketing techniques. In this article we apply this information/requirement/product definition technique to environmental pollution control technology to show how a range of information outputs and services needs to be developed to satisfy various requirements. This technique could be applied to virtually any applications are

摘要:

AbstractThis article shows that if simple foundations of the cost structure are taken into consideration, high values of both precision and recall are not necessarily the goal when searching in an information system. When the cost structure is known, the optimal value of recall and the optimal value of precision can be found. Both values are functions of relative prices/costs only.

摘要:

AbstractSimple automatic coding of most descriptive titles generates NEPHIS (NEsted PHrase Indexing System) input strings of sufficiently good quality for permuted index production. The coding algorithm is based on assumptions about three ranks of delimiter, and about phrase‐element dependency, in title language; NEPHIS facilitates human recoding of the few titles violating these assumptions. Initially implemented in DECsystem‐10 DPL, but applicable also to microcomputer systems, the algorithm requires only brief lists of delimiters plus an input set containing one or more titles; stoplisting is optio

摘要:

AbstractAuthors with Japanese surnames are needlessly confused with each other in citations and bibliographies because their names are extensively duplicated. This report examines the amount of duplication and proposes reducing it by mechanical derivation of middle initials.
