Abstract: "Traditionally, scholarly impact and visibility have been measured by counting publications and citations in the scholarly literature. However, increasingly scholars are also visible on the Web, establishing presences in a growing variety of social ecosystems. But how wide and established is this presence, and how do measures of social Web impact relate to their more traditional counterparts? To answer this, we sampled 57 presenters from the 2010 Leiden STI Conference, gathering publication and citations counts as well as data from the presenters' Web "footprints." We found Web presence widespread and diverse: 84% of scholars had homepages, 70% were on LinkedIn, 23% had public Google Scholar profiles, and 16% were on Twitter. For sampled scholars' publications, social reference manager bookmarks were compared to Scopus and Web of Science citations; we found that Mendeley covers more than 80% of sampled articles, and that Mendeley bookmarks are significantly correlated (r=.45) to Scopus citation counts.

The sister organisation of W3C, the Web Science Trust (www.webscience.org) proposes to create a Create a global "Web Observatory".

LexiURL Searcher automatically analyses the impact of collections of documents or web sites, and creates network diagrams of collections of web sites. It automatically submits queries to search engines and process the results.

We used the databases of ISI and Ulrich's as our primary sources and estimate that the total number of articles published in 2006 by 23 750 journals was approximately 1 350 000.\nUsing this number as denominator it was also possible to estimate the number of articles which are openly available on the web in primary OA journals (gold OA). This share turned out to be 4.6 % for the year 2006. In addition at least a further 3.5 % was available after an embargo period of usually one year, bringing the total share of gold OA to 8.1%\nUsing a random sample of articles, we also tried to estimate the proportion of the articles published which are available as copies deposited in e-print repositories or homepages (green OA). Based on the article title a web search engine was used to search for a freely downloadable full-text version. For 11.3 % a usable copy was found. Combining these two figures we estimate that 19.4 % of the total yearly output can be accessed freely.

"a study is undertaken of a selection of papers from the fie ld of c ommunication, comparing the number of cit ations received with their 2.0 i ndicators. The results s how that the most cited articles within recent years also have significantly hi gher altmetric indicators. Next follows a review of the principal empirical studies undertaken, centering on the correlations between bibliometric and al ternative indicators. To conclude, the main limitations of altmetrics are highlighted , alongside a reflective consideration of the role altmetrics may play in capturing the impact of research in Web 2.0 platforms"

Incorporating web 2.0 behaviors (e.g. recommending, commenting, social bookmarking) into the array of valid reserch metrics is a long work in progress...

"The information science field of webometrics is "the study of the quantitative aspects of the construction and use of information resources, structures and technologies on the web drawing on bibliometric and informetric approaches" [1] or, more generally, "the study of web-based content with primarily quantitative methods for social science research goals using techniques that are not specific to one field of study"[2]."

Computers and the web have transformed homes and businesses, and could do the same for education and training. Known as "eLearning," this can be as simple as accessing a school timetable online, or as complex as running virtual communities for sharing and creating knowledge.

Excerpt: "will involve the use of an ecosystem of interacting web-based resources, including the infrastructure provided by the Virtual Observatory, data provisioning services from Astronomy archives, a variety of analysis services such as Astrometry.net, notification services such as skyalert.org, and visualization services such as CDS's Aladin and Microsoft's WorldWideTelescope."

From Artifacts to Aggregations: Modeling Scientific Life Cycles on the Semantic Web

Intricate maps of science have been created from citation data to visualize the structure of scientific activity. However, most scientific publications are now accessed online. Scholarly web portals record detailed log data at a scale that exceeds the num

Formerly, the impact of authors and their scientific production was measured by the average citation frequencies of journals publishing their research: the Journal Impact Factor (JIF), calculated by the Institute for Scientific Information (ISI) in the United States and published annually in the Journal Citation Reports (JCR)-the most frequently used quantitative indicator to measure the quality/value/impact of research works published in the core international journals. It has been suggested that, by calculating the number of webpages pointing to a given site, analogously, a Web Impact Factor can be calculated as a way of comparing the attractiveness of sites or domains on the World Wide Web.

Rich Results is a book search algorithm takes into account more than 100 "signals," individual data categories that Google statistically integrates to rank your results. When you search for a book, Google Books doesn't just look at word frequency or how closely your query matches the title of a book. They now take into account web search frequency, recent book sales, the number of libraries that hold the title, and how often an older book has been reprinted.
