Analyzing the Structure of U.S. Patents Network

Abstract. The U.S. patents network is a network of almost 3.8 millions patents (network vertices) from the year 1963 to 1999 We analyzed the U.S. patents network with the tools of network analysis in order to get insight into the structure of the network as an initial step to the study of innovations and technical changes based on patents citation network data. In our approach the SPC (Search Path Count) weights, proposed by Hummon and Doreian (1989), for vertices and arcs are calculated first. Based on these weights vertex and line island

The value of indirect ties in citation networks:SNA analysis with OWA operator weights

This paper seeks to advance the theory and practice of the dynamics of complex networks in relation to direct and indirect citations. It applies social network analysis (SNA) and the ordered weighted averaging operator (OWA) to study a patent citations network. So far the SNA studies investigating long chains of patents citations have rarely been undertaken and the importance of a node in a network has been associated mostly with its number of direct ties. In this research OWA is used to analyse complex networks, assess the role of indirect ties, and provide guidance to reduce complexity for decision makers and analysts. An empirical example of a set of European patents published in 2000 in the renewable energy industry is provided to show the usefulness of the proposed approach for the preference ranking of patent citations

Congress UPV Proceedings of the 21ST International Conference on Science and Technology Indicators

This is the book of proceedings of the 21st Science and Technology Indicators Conference that took place in València (Spain) from 14th to 16th of September 2016. The conference theme for this year, ‘Peripheries, frontiers and beyond’ aimed to study the development and use of Science, Technology and Innovation indicators in spaces that have not been the focus of current indicator development, for example, in the Global South, or the Social Sciences and Humanities. The exploration to the margins and beyond proposed by the theme has brought to the STI Conference an interesting array of new contributors from a variety of fields and geographies. This year’s conference had a record 382 registered participants from 40 different countries, including 23 European, 9 American, 4 Asia-Pacific, 4 Africa and Near East. About 26% of participants came from outside of Europe. There were also many participants (17%) from organisations outside academia including governments (8%), businesses (5%), foundations (2%) and international organisations (2%). This is particularly important in a field that is practice-oriented. The chapters of the proceedings attest to the breadth of issues discussed. Infrastructure, benchmarking and use of innovation indicators, societal impact and mission oriented-research, mobility and careers, social sciences and the humanities, participation and culture, gender, and altmetrics, among others. We hope that the diversity of this Conference has fostered productive dialogues and synergistic ideas and made a contribution, small as it may be, to the development and use of indicators that, being more inclusive, will foster a more inclusive and fair world

Étudier la géographie des activités et des collectifs scientifiques dans le monde : de la croissance du système de production contemporain aux dynamiques d'une spécialité, la réparation de l'ADN

This thesis considers the geography of scientific activities through its productive dimension (publications retrieved from bibliographic databases). An original method is designed which relies on two principles: taking the urban area as an elementary level of analysis to study the repartition and organization of research activity at the world scale, taking into account co-authorship data to deduce networks of scientific collaborations between places. The main results show a trend toward the spatial diffusion of production activity at several scales, mitigating the monopoly of hegemonic and over-represented areas in the whole corpus of scientific references considered (SCI Expanded). A case study is realized on a research field in molecular biology: DNA Repair. Considering the role of individual trajectories, it explains the geography of the emergence of the scientific specialty as well as the spatial diffusion of a problem area related to the field of DNA Transcription.Cette thèse envisage la géographie des activités scientifiques à travers leur dimension productive (les publications des chercheurs). La méthode définie permet de localiser et d’analyser à plusieurs dates la production et les réseaux de collaboration entre chercheurs à l'échelle mondiale depuis le niveau de l’agglomération urbaine. Les résultats montrent un mouvement récent de diffusion de l’activité à un nombre croissant de lieux, atténuant le monopole d’espaces autrefois hégémoniques et sur-représentés dans le corpus de références étudié (le Science Citation Index Expanded). Une étude de cas est réalisée sur un domaine de recherche en biologie moléculaire : la réparation de l'ADN. Considérant le rôle des trajectoires individuelles, elle aborde les principes géographiques d'émergence de la spécialité et la diffusion spatiale d'une question de recherche associée au domaine de la transcription de l'ADN
