Revista Española de Documentación Científica, 39(4): e149. doi: http://dx.doi.org/10.3989/redc.2016.4.1405 Abstract:The main objective of this paper is to identify and define the core characteristics of the set of highly-cited documents in Google Scholar (document types, language, free availability, sources, and number of versions), on the hypothesis that the wide coverage of this search engine may provide a different portrait of these documents with respect to that offered by traditional bibliographic databases. To do this, a query per year was carried out from 1950 to 2013 identifying the top 1,000 documents retrieved from Google Scholar and obtaining a final sample of 64,000 documents, of which 40% provided a free link to full-text. The results obtained show that the average highly-cited document is a journal or book article (62% of the top 1% most cited documents of the sample), written in English (92.5% of all documents) and available online in PDF format (86.0% of all documents). Yet, the existence of errors should be noted, especially when detecting duplicates and linking citations properly. Nonetheless, the fact that the study focused on highly cited papers minimizes the effects of these limitations. Given the high presence of books and, to a lesser extent, of other document types (such as proceedings or reports), the present research concludes that the Google Scholar data offer an original and different vision of the most influential academic documents (measured from the perspective of their citation count), a set composed not only of strictly scientific material (journal articles) but also of academic material in its broadest sense.Keywords: Google Scholar; academic search engines; highly-cited documents; academic books; open access. Un panorama académico de dos caras: retrato de los documentos altamente citados en Google Scholar (1950-2013)Resumen: El principal objetivo de este trabajo es identificar el conjunto de documentos altamente citados en Google Scholar y definir sus características nucleares (tipología documental, idioma, disponibilidad en abierto, fuentes y número de versiones), bajo la hipótesis de que la amplia cobertura del buscador podría proporcionar un retrato diferente de este conjunto documental a la ofrecida por las bases de datos tradicionales. Para ello, se ha realizado una consulta por año (desde 1950 hasta 2013) identificando los 1000 documentos más citados y obteniendo una muestra final de 64.000 registros (el 40% de los cuales proporcionaban un enlace al texto completo). Los resultados muestran que el documento altamente citado "promedio" es un artículo de revista o libro (éstos constituyen el 62% del top 1% de los documentos más citados de la muestra), escrito en inglés (92.5%) y disponible online en PDF (86% de la muestra). Aun así, se debe indicar la existencia de error...

Abstract. The use of widely-used metadata standards is essential to guarantee the visibility and retrieval of documents stored in open repositories. Attention should be paid to the creation and exchange of meaningful metadata to enhance interoperability amongst repositories and provide value added services. Since 2005 the Food and Agriculture Organization of the United Nations (FAO) provides the agricultural information management community with standards, services and tools to assist open repositories in benefiting from the advantages offered by Semantic Web publishing. This paper presents the work that FAO carries out in recommending standards for the encoding and exchange of metadata while also reviewing techniques to help navigate within open repositories and services. It talks about how to improve the visibility of repository content and explains the benefits of integrating subject vocabulary tools expressed in SKOS. It concludes with a presentation of use cases integrating these recommendations into DSpace and Drupal customizations.

“…Webometria opisuje w sposób ilościowy proces komunikacji naukowej, do tego celu korzysta z zasobów dostępnych publicznie w sieci, także z tej, określanej mianem niewidocznej lub ukrytej. Analizowane są też obiekty cyfrowe znajdujące się w uczelnianych bazach danych, repozytoriach oraz otwarte czasopisma elektroniczne 21 . Ranking Repozytoriów Uczelni Świata nie jest najstarszym rozwijanym przez Cybermetrics Lab, pierwszym był Webometryczny Ranking Uniwersytetów Świata, który istnieje już od 2004 r. Później natomiast, powstały rankingi: ośrodków badawczych -od 2006 r., repozytoriów -od 2008 r., szpitali -od 2008 r. oraz szkół biznesu i MBA -od 2008 r. do 2012 r. Rankingi aktualizowane są dwa razy w roku.…”

Abstract:The univer sities ar e subjects of the continuous evaluation, not only in terms of their educational offer and the quality of research, but also in the commercialization of new technologies and their industry transfer. The research output, in the form of scientific publishing, being accessed via institutional repositories, is also taken under consideration and the university e-learning courses are the essential, too. The results of these evaluations are presented in the form of various rankings -domestic and international. The most recognized and important are: the "Perspectives" produced by the Educational Foundation, the report of the Ministry of Science and Higher Education and the Webometrics Ranking of World Universities. The assumption, that soon the obtained results from such evaluation of the universities, will have the much more crucial influence on the budget resources and their allocation from public money, becomes the reality. The supporting tool named POL-on for the financial decision-making processes among others, is recently under implementation by the Ministry of Science and Higher Education. The procedure of input data delivery to this system by universities has been recently legalized by the reviewed act on the science financing. Hence, in the current legal state, questions of the role of university library arise in terms of management the institutional repositories, bibliographic databases of the university scientific publications and research information systems. Additionally, in the paper, the analysis of openness and resources type in Polish repositories registered in Ranking Web of World repositories, will be performed.Słowa kluczowe: Zintegr owany System Infor macji o Nauce i Szkolnictwie Wyż-szym POL-on, systemy zarządzania wiedzą, rankingi szkół wyższych Rolę biblioteki akademickiej w systemie zarządzania wiedzą szkoły wyż-szej wyznacza między innymi konieczność gromadzenia, przetwarzania i przesyłania coraz większej liczby informacji i danych do różnych instytucji. Na podstawie tych danych uczelnie mogą być oceniane oraz porównywane.W coraz większym stopniu funkcjonowanie szkół wyższych podlega konkurencji, w której jakość oferowanych usług jest istotnym elementem procesu oceny uczelni. Władze uczelni zwracają uwagę na dbałość o dobry wizerunek instytucji, właściwie prowadzony PR (public relations) i wykorzystują w tym
