The most influential journals: Impact Factor and Eigenfactor

Bibliometricians have introduced various scales of ranking journals; some based on publications, some based on usage as well, including the internet, using social networking analysis. Bollen et al. (1) recently concluded that no single indicator adequately measures impact and the IF is at the periphery of 39 scales analyzed. But there is a new parameter, the Eigenfactorâ„¢, which attempts to rate the influence of journals (www.eigenfactor.org). The Eigenfactorâ„¢ ranks journals in a manner similar to that used by Google for ranking the importance of Web sites in a search.

Research Front Maps from Thomson Reuters

Monday, April 20th, 2009

From the Web Site:

Research fronts are clusters of highly cited papers and research front maps are diagrammatic representations of the co-citation links among the highly cited papers that comprise the cluster. Fronts are selected from the Research Fronts section of Essential Science Indicators from Thomson Reuters which is updated every two months. Some maps also link to author commentaries for specific papers.

Each circle represents a highly cited paper whose bibliographic information is displayed when the user clicks on the circle. The solid lines between circles represent the strongest co-citation links for each paper (that is, indicating that the papers are frequently cited together); weaker links are indicated by dashed lines. Papers close to each other on the map are generally more highly co-cited. The most recent paper(s) are indicated in pink.

Citation Briefs: Face Recognition Research, the Top 20 Institutions

Thursday, April 16th, 2009

Direct to Article:

From the Article:

These institutions are the top 20 ranked by total cites out of a pool of 2,674 institutions publishing on this topic, based on a keyword search for “face recog*” OR “face ident*” OR “face detect*” OR “view-based recog*” OR “object recog*” in the titles, abstracts, and keywords sections of original articles, reviews, and proceedings papers. The data pool was also narrowed by field.

The resulting list of institutions shows that face recognition technology is of international interest; fourteen of the institutions are US-based, three are from Europe, two from Asia, and one is from Canada. Research is being conducted by universities, government organizations, and the private sector. Fifteen of the organizations are academic, two are governmental, two are industrial, and one is an academic/governmental partnership.
