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<http://www.utc.fr/>.
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 <http://exalead.com/> (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<http://guess.wikispot.org/The_GUESS_.gdf_format>file
of row data (download
it<http://gephi.org/wp-content/uploads/2008/10/ipr-semantic-graphe.gdf>
and
feel free to make your own viz !), spatialized the graph in Gephi with
a *force-vector
algorithm <http://iv.slis.indiana.edu/lm/lm-networks.html>* (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
inSVG<http://en.wikipedia.org/wiki/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 <http://www.inkscape.org/>, to finally build the PDF
files.
