From theresults of recent studies, the authors conclude that the value of impact indicators of researchactivities at the level of an institution or a country strongly depend upon whether one includes orexcludes research publications in SCI covered journals written in other languages than in English.Additional material was gathered to show the distribution of SCI papers among publicationlanguages. Finally, the authors make suggestions for further research on how to deal with this typeof problems in future national research performance studies.

We sought to compare the newly introduced SCImago journal rank (SJR) indicator with the journal impact factor (IF). We retrieved relevant information from the official Web sites hosting the above indices and their source databases. The SJR indicator is an open-access resource, while the journal IF requires paid subscription. The SJR indicator (based on Scopus data) lists considerably more journal titles published in a wider variety of countries and languages, than the journal IF (based on Web of Science data). Both indices divide citations to a journal by articles of the journal, during a specific time period. However, contrary to the journal IF, the SJR indicator attributes different weight to citations depending on the "prestige" of the citing journal without the influence of journal self-citations; prestige is estimated with the application of the PageRank algorithm in the network of journals. In addition, the SJR indicator includes the total number of documents of a journal in the denominator of the relevant calculation, whereas the journal IF includes only "citable" articles (mainly original articles and reviews). A 3-yr period is analyzed in both indices but with the use of different approaches. Regarding the top 100 journals in the 2006 journal IF ranking order, the median absolute change in their ranking position with the use of the SJR indicator is 32 (1st quartile: 12; 3rd quartile: 75). Although further validation is warranted, the novel SJR indicator poses as a serious alternative to the well-established journal IF, mainly due to its open-access nature, larger source database, and assessment of the quality of citations.Falagas, M.

In the first part (sections 1, 2 and 3) we briefly describe the project and the software. In sections 4 and 5, we discuss the weaknesses of the current publishing model and the benefits deriving from the adoption of Semantic Web technologies, outlining how the Semantic Web vision can help to overcome the inefficiencies of the current model. In the last two sections (6 and 7), we present two experimental applications, developed on top of HyperJournal, with the purpose of demonstrating how the technologies can affect the daily work of scholars. The first application is a tool for graphically visualizing the network of citations existing between articles and their authors, and for performing bibliometric measurements alternative to the ISI Impact Factor. The second is a tool for automatically extracting references from non-structured textual documents, which is part of a tool-chain for the extraction of hidden semantics.

In the time since Thomson Scientific (a Thomson business) first studied the citation impact of Open Access (OA) journals using the 2002 Journal Citation Reports® (JCR®), discussion of the value and viability of this access model has continued. When the 2003 JCR was published in June 2004, we took the opportunity to re-examine the coverage and citation performance of OA journals in the ISI® citation databases in the context of the emerging issues in the open access debate. We have also broadened the study to consider not only OA journals, but the potential influence of other types of OA publishing on the availability of materials covered by Thomson products. An increasing number of journals covered in the ISI citation databases are adopting an OA distribution model. In addition, we continue to evaluate and select new OA journals. Although the largest number of OA journals is in Medicine and Life Sciences, OA journals in Physics, Engineering & Mathematics are more frequently among the highest ranking journals in their categories. It is still the case that more of the currently available OA journals rank in the lower half of their subject category, despite the presence of some OA journals in the top ranks. Within the collection of OA titles, however, there is a notable tendency to rank higher by Immediacy Index than by Impact Factor, irrespective of the subject. Open Access journals are not necessarily new publications. In fact, Open Access at the journal level comprises a complex picture of availability. Many established journals make only a few recent years of content available online, while the majority of their content is accessible only through traditional access paths. Other established journals, having moved to OA distribution, offer access to many years of older content as well. The evolving environment of scholarly publishing includes additional avenues for making content openly available. Our findings suggest that over 55% of the journals and over 65% of the articles indexed in Web of Science® in 2003 are produced by publishers who permit some form of self-archiving, and could be made OA by author archiving.
