A Study of HTML Title Tag Creation Behavior of Academic Web Sites
Full text linkThe HTML title tag information should identify and describe exactly what a web page contains. This paper analyzes the Title element and raises a significant question: "Why is the title tag important?" Search engines base search results and page rankings on certain criteria. Among the most important criteria is the presence of the search keywords in the title tag. This research concentrates on exploring the retrieval results of Google in retrieving web pages without the title tag. More than one million of academic web pages are found to be untitled, that is, they have not used the title tag
A k-Nearest-Neighbour Method for Classifying Web Search Results with Data in Folksonomies
No full textTraditional Web search engines mostly adopt a keyword-based approach. When the keyword submitted by the user is ambiguous, search result usually consists of documents related to various meanings of the keyword, while the user is probably interested in only one of them. In this paper we attempt to provide a solution to this problem using a k-nearest-neighbour approach to classify documents returned by a search engine, by building classifiers using data collected from collaborative tagging systems. Experiments on search results returned by Google show that our method is able to classify the documents returned with high precision

Information science in France. Emergence, Evolution and Perspectives: In LIBRARY AND INFORMATION SCIENCE TRENDS AND RESEARCH: EUROPE, Amanda Spink & Jannica Heinstrom (eds.)
No full textTo appear in Amanda Spink and Jannica Heinstrom (eds.), "Library and Information Science Trends in Europe, Emerald Library and Information science book seriesInternational audienceAs an academic specialty in the French higher education, Information Science was shaped by short-term government policies implemented after world war II until the late nineties. The field was officially recognised in 1974 as part of an interdisciplinary field named "Information and Communication Science". Information Science was seen by the successive French governments as an instrument with which to gain information independence from the United States. The aim was to develop information infrastructures (telecommunications, databases, servers), hence to develop an industry rather than a science. This led to narrowing the focus of the field to only one type of information - scientific and technical information. The first higher education curricula and doctoral programs were technologically-oriented, driven by the need to train information professionals rather than scientists. Little attention was paid to research on conceptual models, on theories and on knowledge organisation which used to be the stronghold of European and French pioneers in bibliography and in documentation (Paul Otlet, Suzanne Briet, Georgette and Eric de Grolier among others). Currently, the trend is to bring information science back to its humanistic origins and to engage in a more theoretical and people-oriented research. However, there is yet no coherent agenda that clearly defines what information science research should be about. There is also little visibility of French information science both at the national and international arena
Information seeking and mediated searching. Part 4. Cognitive styles in information seeking
No full textThis is the fourth in a series resulting from a joint research project directed by Professor Tom Wilson in the United Kingdom and Dr. Amanda Spink in the United States. The analysis reported here sought to test a number of hypotheses linking global/analytic cognitive styles and aspects of researchers' problem-solving and related information-seeking behavior. One hundred and eleven postdoctoral researchers were assessed for Witkin's field dependence/independence using Riding's Cognitive Styles Analysis and for Pask's holist/serialist biases using items from Ford's Study Processes Questionnaire. These measures were correlated with the researchers' perceptions of aspects of their problem-solving and information-seeking behavior, and with those of the search intermediary who performed literature searches on their behalf. A number of statistically significant correlations were found. Field-independent researchers were more analytic and active than their field-dependent counterparts. Holists engaged more in exploratory and serendipitous behavior, and were more idiosyncratic in their communication than serialists
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
