José Luis Ortega: Web Analyst

Research evaluation: When I was R&D Analyst of the CSIC I written several internal reports and papers on the research activity of this organism, concretely, on patents [1] and research contracts. I also worked with the CDTI analyzing the network collaboration in the 6th Framework Programme [2,3,4,5].

Quantitative web studies: during my participation in the Cybermetrics Lab, I developed some researches in several lines around the Web from a quantitative view.

Web usage studies: Using the web transaction logs, I have made some studies on the users’ behaviour in a web site as a way to improve the web architecture of the site [6]. I have studied if they spend more time in a site depending of if they came from a search engine query, a web link of from the root of the site [7]. Also, I graphed the path network of a website as a way to evaluate its web architecture [8].

Networks visualization: This was the main line; in fact, it was the theme of my PhD Thesis. I have made network maps of the European [9], Nordic [10], Ibero-american [11] and World-class [12] universities on the Web. The main result is that the university network graphs have scale-free and Small-worlds properties. The network is set up by local or regional sub-networks which are aggregated by geographical or linguistic criteria. These groups are linked between them through gateway universities that mediate between the sub-network and the main one.

Web demography: This line assumes that the web pages birth, grow and died. In this sense, I studied the age of the web as well as developed several indicators to measure the obsolescence of web spaces [13]. A longitudinal study showed that the Web grows in an irrational process and it increases destroying the previous Web [14].

University rankings: I have collaborated in the design and building of one of the most important University rankings, Ranking Web of World Universities. The methodology and the main highlights were published [15,16].

Web bibliometrics: This recent line is focused on the study of the research activity according to web-based services such as Google Scholar Citations and Microsoft Academic Search [19]. In this sense, I have made a Map of Science throught the label used by each profile [17] and a collaboration study at institutional and national level [18] using Google Scholar Citations. As a result, I published a book on academic search engines [20].

Altmetrics: this new field is devoted to explore the meaning of alternative indicators from academic social sites for research evaluation.
