Se ha dado a conocer el Ranking WEB de universidades en el mundo (6 mil universidades). Más abajo se muestran los resultados para las 100 universidades top de Amèrica Latina.
Metodología
The unit for analysis is the institutional domain, so only universities and research centres with an independent web domain are considered. If an institution has more than one main domain, two or more entries are used with the different addresses.
The first Web indicator, Web Impact Factor (WIF), was based on link analysis that combines the number of external inlinks and the number of pages of the website, a ratio of 1:1 between visibility and size. This ratio is used for the ranking, adding two new indicators to the size component: Number of documents, measured from the number of rich files in a web domain, and number of publications being collected by Google Scholar database.
Four indicators were obtained from the quantitative results provided by the main search engines as follows:
Size (S). Number of pages recovered from four engines: Google, Yahoo, Live Search and Exalead.
Visibility (V). The total number of unique external links received (inlinks) by a site can be only confidently obtained from Yahoo Search.
Rich Files (R). After evaluation of their relevance to academic and publication activities and considering the volume of the different file formats, the following were selected: Adobe Acrobat (.pdf), Adobe PostScript (.ps), Microsoft Word (.doc) and Microsoft Powerpoint (.ppt). These data were extracted using Google, Yahoo Search, Live Search and Exalead.
Scholar (Sc). Google Scholar provides the number of papers and citations for each academic domain. These results from the Scholar database represent papers, reports and other academic items.
The four ranks were combined according to a formula where each one has a different weight but maintaining the ratio 1:1:
The inclusion of the total number of pages is based on the recognition of a new global market for academic information, so the web is the adequate platform for the internationalization of the institutions. A strong and detailed web presence providing exact descriptions of the structure and activities of the university can attract new students and scholars worldwide.
The number of external inlinks received by a domain is a measure that represents visibility and impact of the published material, and although there is a great diversity of motivations for linking, a significant fraction works in a similar way as bibliographic citation.
The success of self-archiving and other repositories related initiatives can be roughly represented from rich file and Scholar data. The huge numbers involved with the pdf and doc formats means that not only administrative reports and bureaucratic forms are involved. PostScript and Powerpoint files are clearly related to academic activities.
Resultados 2009
The 2009 edition of the Ranking Web of World Universities (http://www.webometrics.info) shows important news. Most of them are due to changes done to improve the academic impact of the open web contents and to reduce the geographical bias of search engines. As a result, the US universities still lead the Ranking (MIT with its huge Open Courseware is again the first, followed by Harvard, Stanford and Berkeley), but the digital gap with their European counterparts (Cambridge and Oxford are in the region’s top) has been reduced. Even more important, some of the developing countries institutions reach high ranks, especially in Latin America where the University of Sao Paulo (38th) and UNAM (44th) benefits from the increasingly interconnected Brazilian and Mexican academic webspaces.
Several countries improves their performance including Taiwan and Saudi Arabia with strong web oriented strategies, Czech Republic (Charles), the leader for Eastern Europe, Spain (Complutense) and Portugal (Minho, Porto) with huge repositories and strong Open Access initiatives. Norway (NTNU, Oslo), Egypt could be also mentioned.
On the other side, the underrated countries are headed by France, with a very fragmented system, Korea, whose student-oriented websites are frequently duplicated, New Zealand, India or Argentina.
Africa is still monopolized by South African universities (Cape Town is the first, 405th), as well as Australian Universities are the best ranked for Oceania (Australian National University, 77th)
Other well performing institutions include Cornell or Caltech in the USA, Tokyo (24th) Toronto (28th), Hong Kong (91st), or Peking (104th). On the contrary, in positions below expected we find Yale, Princeton, Saint Petersburg, Seoul and the Indian Institutes of Science or Technology.
