| Sumario: | Altmetrics is a movement that aims to capture new and previously invisible types of impact of scholarly publications on social web platforms such as news sites, Wikipedia, blogs, microblogs, social bookmarking tools and online reference managers. This thesis aimtries to explore the suitability and reliability of two altmetrics resources: Mendeley, a social reference manager website, and Wikipedia, a free online encyclopedia, written collaboratively by the people who use it. At present, Wikipedia is the largest online encyclopedia. The main objectives of this thesis are to explore the use of reference management software and Wikipedia to estimate the readership of academic literature and to compare the evolution in the coverage of LIS literature by altmetric sources and by citation indexes. To reach these objectives, three different studies were designed. The general method to achive toobtain the initial data set was to search is that we used the Social Sciences Citation Index to retrieve articles and reviews published and indexed in the category “Information Science & Library Science”. Each record was then searched in Mendeley to obtain the number of bookmarks of the paper and the academic status of the users. Additonally, we performed a fifteen-month longitudinal study of the evolution of bookmarks in Mendeley. Afterwards, we searched for each of these articles in Wikipedia, and retrieved all the entries in which they were cited. The Results results of these studies show that the correlation between bookmarks and citations was moderate and the overlap between the most frequently bookmarked and the most frequently cited papers increased over time. A significant share of the bookmarks were made by students and professionals, although the shares of bookmarks made by different categories of users changed as time went by. Reviews were bookmarked more frequently than articles, and papers in English had more bookmarks than papers in any other language. Also results reveal severe limitations in the use of Wikipedia citations for research evaluation. Lack of standardization and incompleteness of Wikipedia references make it difficult to retrieve them. The number of Wikipedia citations is very low, A significant number of references are cited in biographical entries about the authors of the articles, resulting in a phenomenon of accumulated advantage. Nearly one-third of the Wikipedia citations link to an open access source, although this result is probably an underestimate of open access availability, given the incompleteness of Wikipedia citations. |
