Growth in scientific production, its importance in economic and social development and the consequent consolidation of science as a public policy object in the second half of the 20thcentury brought with it them the need to develop indicators capable of measuring and evaluating the performance of complex scientific activities in general, and of its components – researchers and institutions – in particular.

In spite of their recognized limitations, bibliometric indicators are the most widely used to evaluate scientific activity and its influence and impact. 13 Bibliometric measurements capable of measuring and qualifying scientific productivity are developed to report the performance of researchers, groups and research institutions and to guide the promotion of scientists, fostering research and personnel training.

Social network analysis software. Social network analysis software (SNA software) is software which facilitates quantitative or qualitative analysis of social networks, by describing features of a network either through numerical or visual representation.

Social network analysis software

Overview[edit] Some SNA software can perform predictive analysis.[5] This includes using network phenomena such as a tie to predict individual level outcomes (often called peer influence or contagion modeling), using individual-level phenomena to predict network outcomes such as the formation of a tie/edge (often called homophily models[6]) or particular type of triad, or using network phenomena to predict other network phenomena, such as using a triad formation at time 0 to predict tie formation at time 1. Network analysis software generally consists of either packages based on graphical user interfaces (GUIs), or packages built for scripting/programming languages. GUI packages are easier to learn, while scripting tools are more powerful and extensible. See also[edit] Network Workbench. GUESS: The Graph Exploration System. Start [Pajek Wiki]

Quelques outils pour visualiser les réseaux sociaux. L’analyse des réseaux sociaux permet de mieux comprendre le comportement des acteurs et des communautés : quelle est la place de l’acteur au sein de l’ensemble ?

Quelques outils pour visualiser les réseaux sociaux

Est-il central ? Périphérique ? Fait-il le lien entre différentes communautés ? Comment est organisée la communauté ? En plusieurs groupes ? Cette analyse permet de comprendre en profondeur le fonctionnement des communautés en ligne. L’analyse des réseaux sociaux se fait en trois temps distincts : la récupération des données, leur analyse et leur visualisation. Sur de petits graphes, il est possible de faire la récupération des données a la main. Les données qui sont récupérées concernent le lien : qui est lié à qui ou à quoi, mais on pourra également s’intéresser au volume d’information produits, à sa fréquence et faire quelques corrélations. Navicrawler est une extension Firefox qui explore le contenu et la structure des pages web. Guess est surtout un outil de rendu, mais il permet également de faire quelques calcul.

Navicrawler. UPDATE: There now a portable version of Firefox with Navicrawler included: More information on these: These folders are zipped.

Navicrawler

Unzip and run “Firefox Portable”. You might have some obvious messages, and after that you have a fully functionnal Firefox 3.6 with Navicrawler installed.These are portable apps, it means that they do not interfere with other versions of Firefox that you might have. They do not install, you have to run them from their folder.Two other extensions are also installed: Flem and Greasemonkey. Regular versions: You can download the Navicrawler 1.7 or the Navicrawler 1.8b (now hosted directly on WebAtlas.fr). The Navicrawler is no longer supported. In this “next generation Navicrawler” you will be able to dynamically change the boundaries of every website, to have graphs with pages and websites at the same time, and to declare aliases (the same website with different domain names).
