Propuesta de indicadores métricos para gestores sociales de noticias: análisis de la prensa digital española en Menéame

Introduction. Social bookmarking sites such as Digg, Meneame, etc. have become a reference for the digital press. Therefore, news producers wish to position themselves in such systems to gain visibility and to increase traffic to their Websites. This paper proposes two bibliometric indicators to calculate the presence and impact of the press in social bookmarking systems, providing both qualitative and quantitative measures. Method. The Weighted Comments Impact (ICP) is proposed as an indicator of the impact of a news medium over a month, and the Media Power Factor (FPM) is proposed as an indicator of the overall impact of a news medium over a month. To validate these parameters, a longitudinal retrospective descriptive analysis of the content of news sent to the Meneame social bookmarking site over sixteen months has been carried out. Results. The validation of the Weighted Comments Impact shows that the digital medium which has reached the highest average value is El Pais, followed by 20 Minutos and El Mundo, which is consistent with the overall ranking of comments received. The validation of the Media Power Factor, however, indicates that 20 Minutos is the digital newspaper with the highest value, followed by El Pais and El Mundo. Conclusions.The main finding of this study is that the parameters proposed are valid for calculating the degree of impact of the digital press in a social bookmarking site.
