“…Google was chosen for extracting Web/URL citation counts because results of previous studies showed that it has provided the most comprehensive [44] and the most stable search results over time [13,45]. Google has good coverage of HTML and non-HTML documents and supported the syntax necessary for extracting both Web and URL citations at the time of this study, as described below.…”

In this paper we introduce a new data gathering method "Web/URL Citation" and use it and Google Scholar as a basis to compare traditional and Web-based citation patterns across multiple disciplines. For this, we built a sample of 1,650 articles from 108 Open Access (OA) journals published in 2001 in four science and four social science disciplines. We recorded the number of citations to the sample articles using several methods based upon the ISI Web of Science, Google Scholar and the Google search engine (Web/URL citations). For each discipline, we found significant correlations between ISI citations and both Google Scholar and Google Web/URL citations; with similar results when using total or average citations, and when comparing within and across (most) journals. We also investigated disciplinary differences. Google Scholar citations were more numerous than ISI citations in our four social science disciplines as well as in computer science, suggesting that Google Scholar is a more comprehensive tool for citation tracking in the social sciences and perhaps also in fast-moving fields where conference papers are highly valued and published online. The results for Web/URL citations suggested that counting a maximum of one hit per site produces a better measure for assessing the impact of OA journals or articles, because replicated web citations are very common within individual sites. The results can be considered as additional evidence that there is some commonality between traditional and Web-extracted citations.

“…and Windows Live constantly crawl the Web and maintain huge searchable databases of the pages that they have found. Search engine results are now widely used for measurement purposes, not only by information researchers in Webometrics (Almind & Ingwersen, 1997;Bar-Ilan, 2004b), and related fields (Foot, Schneider, Dougherty, Xenos, & Larsen, 2003;Park, 2003;Pennock, Flake, Lawrence, Glover, & Giles, 2002) but also by commercial activities such as Web analytics and search engine optimisation. Hence, there is a need for research into the reliability of the results that search engines deliver and two relevant issues are discussed here.…”

Although designed for general Web searching, Webometrics and related research commercial search engines are also used to produce estimated hit counts or lists of URLs matching a query. Unfortunately, however, they do not return all matching URLs for a search and their hit count estimates are unreliable. In this article, we assess whether it is possible to obtain complete lists of matching URLs from Windows Live, and whether any of its hit count estimates are robust. As part of this, we introduce two new methods to extract extra URLs from search engines: automated query splitting and automated domain and TLD searching. Both methods successfully identify additional matching URLs but the findings suggest that there is no way to get complete lists of matching URLs or accurate hit counts from Windows Live, although some estimating suggestions are provided.

“…Fuera de Europa, se pueden destacar los numerosos análisis de universidades asiáticas y orientales, como Israel (Bar-Ilan, 2003), China (Qiu y otros, 2004) e Irán (Kousha y Horri, 2004), así como de áreas más amplias como todo el oriente medio (Noruzi, 2006) e incluso de las relaciones de Asia con Europa (Park y Thelwall, 2006). En América destacan fundamentalmente los trabajos realizados en los países suramericanos, donde merece atención especial el análisis del espacio académico chileno realizado por Baeza-Yates y Graells 1 y los trabajos de González Martín y Aguillo (1999), Aguillo (2005) …”

Revista Española de Documentación Científica, 36(3):e017. doi: http://dx.doi.org/10. 3989/redc.2013.3.958 Resumen: Se presenta un análisis descriptivo del sistema universitario español en la Red durante 2010, mediante la identificación, recopilación y análisis de una muestra de entidades y URLs asociados, tanto a nivel de universidad como de unidades universitarias clasificadas en instituciones y productos. Se analiza la cantidad de instituciones con URL vá-lida a efectos de análisis cibermétricos, el tipo de sintaxis de URL subdominio o subdirectorio, así como la detección de prácticas de multidominios y redireccionamientos. Para las unidades con área del conocimiento identificable facultades, escuelas, departamentos, y grupos, centros e institutos de investigación, se realiza igualmente un análisis temático. Los resultados indican que el espacio académico español tiene una estructura compleja, donde abundan las prácticas de redireccionamiento, multidominio, con un predominio de los subdirectorios en las instituciones y subdominios en los productos, y donde las ciencias naturales tienen, en número de entidades y URLs asociados, una presencia mayoritaria.Palabras clave: Sistema universitario; cibermetría; webometría; instituciones universitarias; productos universitarios; análisis temático; sintaxis de URLs; España. Spanish university space on the Web (2010): descriptive study of academic institutions and products through the analysis of subdomains and foldersAbstract: A descriptive analysis of the Spanish university system on the Net during 2010 is presented, through the identification, collection and analysis of a sample of entities (and associated URLs), at both the level of universities and university units (classified into institutions and products). An analysis is made of the number of institutions with valid URLs suited for cybermetric analysis purposes and the type of URL syntax (subdomain or subdirectory). Likewise, multi-domain and redirection practices are detected. For units with an identifiable area of knowledge (faculties, schools, departments, and research groups, centers and institutes), a thematic analysis is also carried out. The results indicate that the Spanish academic space has a complex structure, with abundant redirection and multi-domain practices, with a predominance of subdirectories in institutions and subdomains in products, and where the natural sciences have -by number of associated entities and URLs -a major presence.
