The objective of this study is to use a clustering algorithm based on journal cross-citation to validate and to improve the
journal-based subject classification schemes. The cognitive structure based on the clustering is visualized by the journal
cross-citation network and three kinds of representative journals in each cluster among the communication network have been
detected and analyzed. As an existing reference system the 15-field subject classification by Glänzel and Schubert (Scientometrics
56:55–73, <cite>2003</cite>) has been compared with the clustering structure.
This research analyzes a “who cites whom” matrix in terms of aggregated journal-journal citations to determine the location
of communication studies on the academic spectrum. Using the Journal of Communication as the seed journal, the 2006 data in
the Journal Citation Reports are used to map communication studies. The results show that social and experimental psychology
journals are the most frequently used sources of information in this field. In addition, several journals devoted to the use
and effects of media and advertising are weakly integrated into the larger communication research community, whereas communication
studies are dominated by American journals.
The present paper focuses on some important requirements for understanding patent searchreports in view of their use for statistical analysis. It is pointed out and illustrated that thecomprehensiveness and the quality of a given search report may vary significantly as a function ofthe patent office drawing up the report. These differences imply consequences with respect to thesafe use and interpretation of the data. The authors stress that a sound analysis based on patentcitation data can only be performed in a meaningful way if the analyst has a minimum knowledgeof the underlying search reports.

As the population ages in Taiwan, stroke research has received greater attention in recent years. Strokes have significant
impacts on the health and well-being of the elderly. To formulate future research policy, information on stroke publications
should be collected. In this research, we studied stroke-related research articles published by Taiwan researchers which were
indexed in the Science Citation Index from 1991 to 2005. We found that the quantity of publications has increased at a quicker
pace than the worldwide trend. Over the years, there has been an increase in international collaboration, mainly with researchers
in the U.S. Article visibility, measured as the frequency of being cited, also increased during the period. It appears that
stroke research in Taiwan has become more globally connected and has also improved in quality. The publication output was
concentrated in a few institutes, but there was a wide variation among these institutes in the ability to independently conduct
research. A wide array of keywords indicated a probable lack of continuity in research. Nevertheless, there was an inverse
relationship between stroke mortality and number of published articles in Taiwan. To improve the quality and efficiency of
stroke research, continuity in research focuses needs to be maintained, and thus funding should be allocated on a long-term
basis to institutes with a proven record of success.

The quality and credibility of Internet resources has been a concern in scholarly communication. This paper reports a quantitative
analysis of the use of Internet resources in journal articles and addresses the concerns for the use of Internet resources
scholarly journals articles. We collected the references listed in 35,698 articles from 14 journals published during 1996
to 2005, which resulted in 1,000,724 citations. The citation data was divided into two groups: traditional citations and Web
citations, and examined based on frequencies of occurrences by domain and type of Web citation sources. The findings included:
(1) The number of Web citations in the journals investigated had been increasing steadily, though the quantity was too small
to draw an inclusive conclusion on the data about their impact on scientific research; (2) A great disparity existed among
different disciplines in terms of using information on the Web. Applied disciplines and interdisciplinary sciences tended
to cite more information on the Web, while classical and experimental disciplines cited little of Web information; (3) The
frequency of citations was related to the reputation of the author or the institution issuing the information, and not to
the domain or webpage types; and (4) The researchers seemed to lack confidence in Internet resources, and Web information
was not as frequently cited as reported in some publications before. The paper also discusses the need for developing a guideline
system to evaluate Web resources regarding their authority and quality that lies in the core of credibility of Web information.
process of editorial selection goes into the construction of the Citation Database journal list” (AMS 2011a ). The dichotomy of included and cited classes of journals makes MathSciNet a different type of tool than JCR for citationanalysis. Furthermore
A comparison has been carried out between the scientific production of Turkish physicists in the periods 1961-1971 and 1994-2000,
by considering articles (written singly or in collaboration with scientists of different nationalities) which have received
at least ten citations. The results show that in 30 years, appreciable increases have occurred in the number of authors making
significant contributions and in the number of papers based on research carried out in Turkey.
