To Wikipedia researchers,
My name is Dr. Kotaro Nakayama from Osaka University in Japan. I would
like to announce our latest visualization system for Wikipedia
Thesaurus, a huge scale "association" thesaurus, based on Java applet.
It allows users to see the relation network among concepts (articles) in
(Please click on the "NetVis" to show the network for a concept)
We did not just visualize the link structure of Wikipedia, but we
calculated the relatedness for all concepts in Wikipedia using pfibf
(Path Frequency - Inversed Backward link Frequency) analogous to tf-idf
in information retrieval (See "Wikipedia Mining for An Association Web
Thesaurus Construction" in WISE2007 for more information if you are
We are conducting several projects such as Wikipedia Thesaurus (Since
2005), Wikipedia Bilingual Dictionary, Wikipedia API and Wikipedia
Ontology. Detailed information about our activities can be found under
the following URL.
There is no doubt that Wikipedia is an invaluable corpus for knowledge
extraction and this is the time to boost the research up by
collaborating each other. I hope our research is of interest to you.
