2 From Bibliometrics to Webometrics Academic arena: The culture of evaluation Huge public resources devoted to research Science policy actions Pushing: Publish or Perish Monitoring: Bibliometric indicators, citation analysis Tools: Citation bibliographic databases Excellence-driven (High impact international journals) Discipline, geographical and linguistic biases Digital revolution New scholarly communication tools Electronic journals, repositories, Open Access initiatives Wider, diverse audiences (not only peers or First World) Informal channels, Web 2.0

3 Webometrics advantage Quantitative analysis, applying bibliometric methods to (Public Web) inter-citing peer-reviewed papers + Interlinked academic web documents Visitors, linkers, downloaders and invokers Readers, users are global (millions!!) Link motivations, linkers are more diverse + Informal results, raw data and multimedia Transparency (anti-fraud, open peer-review) + Supporting contents Learning material, knowledge resources, other tools + Institutional, personal info If Web Publish or Perish Easy access, cheap publication, rich contents Web indicators useful for scientific evaluation

4 Monitoring Academic Webspace Tools Direct analysis: Robots, crawlers Indirect analysis: Commercial Search Engines (Google, Yahoo!, Bing, Exalead) Methods Use of relevant web variables Web publication, links exchanged, visits and visitors Grouping and networking according institutional, geographical or disciplinary criteria Better naming standards for Web pages, files, sites, domains or links Institutional site (specially in the academia) From citation to sitation (site citation) Big numbers involved (orders of magnitude higher)

5 Webometrics of Academic Institutions Universities and Research Organizations are very complex Different missions Research, scientific publication International cooperation, scientific events Education Teaching, open learning Third Mission Knowledge, technological transfer Socio-cultural activities Other academic/para-academic activities Libraries, University Hospitals, Museums, Zoos, Botanical Gardens, TV & Radio Stations, Theaters, Sports An holistic approach is needed Web indicators reflect better the organization, activities, results

21 Ranking Web of Universities Published since 2004, it is the largest and most updated Directory of universities web domains, with more than 18,000 Higher Education Institutions from all over the World There are two editions per year (January & July) covering the Top 8,000 universities according to web indicators: Activity (50%) and Visibility (50%)

22 Final comments Electronic publication (Web!) is already the most important scholarly communication tool Web should play a key role in the evaluation of the academic activities, scientific research, technological development and the socio-cultural commitment of the academia Quantitative Web indicators are suited for playing that role and promoting Open Access initiatives as Web Publish or Perish is the new motto Webometrics research offers plenty of opportunities for developing theoretical and empirical analysis given the diversity of new tools and techniques currently available
