A heuristic approach to author name disambiguation in bibliometrics databases for large-scale research assessments
No full textNational exercises for the evaluation of research activity by universities are becoming regular practice in ever more countries. These exercises have mainly been conducted through the application of peer-review methods. Bibliometrics has not been able to offer a valid large-scale alternative because of almost overwhelming difficulties in identifying the true author of each publication.We will address this problem by presenting a heuristic approach to author name disambiguation in bibliometric datasets for large-scale research assessments. The application proposed concerns the Italian university system, comprising 80 universities and a research staff of over 60,000 scientists. The key advantage of the proposed approach is the ease of implementation. The algorithms are of practical application and have considerably better scalability and expandability properties than state-of-the-art unsupervised approaches. Moreover, the performance in terms of precision and recall, which can be further improved, seems thoroughly adequate for the typical needs of large-scale bibliometric research assessments

Superiumentarius (Suet. Claud. 2,2). L’imperatore Claudio autore di epigrammi?
No full textAccording to Suet., Claud. 2, 2 in a "libellus" Claudius complained about his master who had been a "superiumentarius". This ironic hyperbole, which refers to the brutal use of whip, seems an allusion to Horace's "plagosus Orbilius", and so suggests the possibility that Claudius'words were part of an epigram. Starting from some recognizable jambic sequences, the author of this article attempts to reconstruct it
Are all citations worth the same? Valuing citations by the value of the citing items
No full textBibliometricians have long recurred to citation counts to measure the impact of publications on the advancement of science. However, since the earliest days of the field, some scholars have questioned whether all citations should be worth the same, and have gone on to weight them by a variety of factors. However sophisticated the operationalization of the measures, the methodologies used in weighting citations still present limits in their underlying assumptions. This work takes an alternative approach to resolving the underlying problem: the proposal is to value citations by the impact of the citing articles, regardless of the length of their reference list. As well as conceptualizing a new indicator of impact, the work illustrates its application to the 2004-2012 Italian scientific production indexed in the WoS. The proposed impact indicator is highly correlated to the traditional citation count, however the shifts observed between the two measures are frequent and the number of outliers not negligible. Moreover, the new indicator shows greater "sensitivity" when used to identify the highly-cited papers
