Semantic graphs of French IPR

Main semantic graph of French intellectual property rights
Semantic graph of French contract rights

These work-in-progress maps are a study produced the last spring for the economist Yann Moulier-Boutang, law professor at the engineer school UTC. They represent the linked terms of vocabulary used on the Web to talk about the intellectual property rights in French language. Datasets come from Exalead SA (web/intranet search engine).

Each node is a term and each edge exists when two terms or expressions are co-cited on a sufficient number of web pages, over more than 120,000 pages. 1283 expressions and 4984 co-citing links have been selected, assuming a representative approach against an exhaustive one. Semantic clusters are represented with node colors in the general map. The contract rights map shows the “imprint” of this cluster (red nodes) inside the overall graph (in grey). The last image is a test to display the imprint of two meta-clusters : the vocabulary of intellectual property rights (in red) versus the one of industrial property rights (in blue).

How we did this ? After an information extraction phase from the Exalead databases and a manual filtering, we made a GDF file of row data (download it and feel free to make your own viz !), spatialized the graph in Gephi with a force-vector algorithm (in a nutshell, two nodes tied by an edge are graphically attracted to each other, otherwise they are rejected), applied some filters to colorize the nodes regarding to which semantic cluster they belong to, and then export the maps in SVG format. The second part of the work consisted in softly improving the rendering and adding contextual informations like names of clusters, main terms clouds, legend…in Inkscape, to finally build the PDF files.
