English abstract

Google Scholar is a search engine that specializes in scientific information and in the identification of the citations that academic papers receive, making it a strong competitor for other citations indexes. For this reason, several studies have attempted to evaluate its capacity as a bibliometric tool. Due to this interest, we present an introduction to its use and the advantages and disadvantages versus Scopus and Web of Science. First, its way of collecting information and features of its interface are analyzed. The following section describes the results that Google Scholar generates. Thirdly, we analyze the coverage of information sources and the different document types to be found, showing how this coverage universe offers different citations versus other products. Finally, we specify the standardization problems of Google Scholar and offer a number of precautions that must be taken into account when using Google Scholar as an evaluation tool.

Spanish abstract

Google Scholar es un buscador especializado en recuperar documentos científicos y en identificar las citas que éstos han recibido, convirtiéndose de esta forma en un competidor de otros índices de citas. Diversos estudios han tratado de valorar su capacidad como herramienta bibliométrica. Debido a este interés se hace una introducción a su uso y a sus ventajas e inconvenientes frente a Web of Science y Scopus. Primero se analiza su modo de recopilar información y las propiedades de su interfaz. A continuación se describen los resultados a los que da lugar el buscador. En tercer lugar se analiza la cobertura de fuentes de información y los diferentes tipos documentales que recoge. Se expone cómo esta cobertura provoca un universo de citación diferente al de otros productos. Finalmente se especifican sus problemas de normalización y se expone una serie de precauciones a la hora de usarlo como herramienta de evaluación.
