Open Access 2007 - 2017: Country and University Level Perspective

Each year the number of Open Access (OA) papers is gradually increasing. We carried out a study investigating 400 universities from 8 countries to examine: i) the total number of OA papers per country, ii) proportion of OA papers published by representative universities in each country classified into three tiers of research quality: high, middle and low, iii) how universities within the same country compare to each other and iv) the growth of OA papers in countries per year. We conclude that among the analysed countries the UK and USA rank first and second respectively, while Russia and India are positioned towards the bottom of the list. We observe no link between the proportion of OA papers published by authors at a university and the university ranking, with some universities in the middle university rank tier having a larger proportion of OA papers than those in the high tier

Bibliometric delineation of scientific fields

International audienceDelineation of scientific domains (fields, areas of science) is a prior task in bibliometric studies at the meso-level, far from straightforward in domains with high multidisciplinarity, variety and instability. The Context section shows the connection of delineation problem to the question of disciplines vs. invisible colleges, through three combinable models: ready-made classifications of science, classical information retrieval searches, mapping and clustering. They differ in the role and modalities of supervision. The Tools section sketches various bibliometric techniques on the background of information retrieval, data analysis, network theory, showing both their power and their limitations in delineation processes. The role and modalities of supervision are emphasized. The section Multiple Networks and Hybridization addresses the comparison and combination of bibliometric networks (actors, texts, citations) and the various ways of hybridization. In the concluding section, typical protocols and further questions are proposed
