El factor de impacto de las revistas científicas: limitaciones e indicadores alternativos

Abstract

Impact Factor measures the average number of times that articles published in the last two years are cited in the current year. In spite of its limitations, the evaluation agencies of some countries like Spain use it in research assessment, generating a deep unease within some circles that consider its use inappropriate and indiscriminate. As an alternative to the Impact Factor of Thomson ISI, other indicators have been proposed, although none of them have achieved sufficient acceptance and widespread use to be systematically applied. Among Spanish initiatives, most notable are the Potential Impact Factor of The Spanish Medical Journals, developed by the Siniac team (Information systems and research activity indicators) from the Instituto de Historia de la Ciencia y Documentación López Piñero (Valencia, Spain), and the índice de impacto de las revistas españolas de ciencias sociales (In-Recs), developed by the EC3 research group at Library and Documentation department of Granada University (Spain).
