Part 1: project profile

Project Name

Wikipedia Category Map

Project Short Description

Wikipedia articles are organized in a hierarchy of categories, manually assigned by users. This process can be considered a huge effort for the collective categorization of human knowledge; the result is a wide and disordered graph which can provide precious information for a variety of applications (natural language processing, information retrieval, ontology building...).

The objective of this project is the development of a tool for the visualization of this graph, providing a way for interacting with it.

GUI Tool Description

Here is shown the main window of the tool.

Starting from the top of the frame there are:

• The field for indicating the Wikipedia site.
• The field for indicating from which category the analisys will be starting from.
• Three button:
  • for generating the RDF file,
  • for generating the graph given the created RDF,
  • for saving the RDF representation of the Wikipedia in a file.
• The text area where the RDF will be shown.

When the "Generate Graph" button is pressed, the frame showed below appears.

Project Resources

Wikiont

It has been developed an ontology for representing the content of Wikipedia. It has been written in RDF and is available at: http://airwiki.elet.polimi.it/rdf/wikiont.rdf

MediaWiki

MediaWiki is a free software wiki package written in PHP for querying the content of the wiki sites. http://www.mediawiki.org/wiki/MediaWiki

Jena

Jena is a Java framework for building Semantic Web applications. It provides a programmatic environment for RDF, RDFS and OWL, SPARQL and includes a rule-based inference engine. In this project is used for reading and writing RDF files.

This library is available at: http://jena.sourceforge.net/

JUNG

JUNG — the Java Universal Network/Graph Framework--is a software library that provides a common and extendible language for the modeling, analysis, and visualization of data that can be represented as a graph.
