English abstract

This work provides a theoretical and practical walk-through of Co-link Analysis, one of the classic techniques for information visualisation that serves as a tool for constructing Maps of Science in Webometrics. An analysis is offered of the steps to be followed, the most suitable data resources, the different kinds of matrices, and how these have to be processed. The results permit distinguishing between the different steps taken and the differences in processing these matrices. The study finds that asymmetrical matrices provide more information than symmetrical ones, that there is greater discrimination with the cosine than with the correlation, and that crawlers obtain more accurate information than search engines.

Spanish abstract

Se hace un recorrido teórico y práctico por el análisis de co–enlaces, una de las técnicas clásicas de la visualización de información para la construcción de mapas de la ciencia en el ámbito de la cibermetría. Se analizan los pasos a seguir, la fuentes de datos más idóneas, los diferentes tipos de matrices y como ha de procesarse cada una. Los resultados nos permiten diferenciar los distintos pasos seguidos y los diferentes modos de procesamiento. Finalmente, se concluye que las matrices asimétricas aportan más información que las simétricas, el coseno tiene un poder de discriminación mayor que la correlación y los crawlers obtienen información más apropiada que los buscadores.
