Semantic Discovery: Discovering Complex Relationships in Semantic Web

A NSF Medium ITR project

'Casar-Rank' Context-Aware Seamantic Association Ranking

Demo mentioned in Aleman-Meza, Halaschek et al.'s Ranking Complex Relationships on the Semantic Web

Ranking Semantic Associations Demo

There is a version of the demo that requires Flash.

There is a live version of the Demo of Ranking Semantic Associations (Alternative Location of: Demo of Ranking Semantic Associations)

The demo is made available in the form of a WAR file to be deployed in Tomcat (tested with version 5.5.11).

  1. Is the source code available?
    We are evaluating a Java version of the underlying code (basically, an API and toolkit). As soon as these components reach an stable status we will make a decision on making the source code available. The first components to be made available will include the applet for visualization (modified from a version of TouchGraph, together with the tomcat-interaction servlet that communicates with the applet)
  2. What queries can I try?
    An easy one, is typing "bush" in both fields, then select George W as one of the entities, and Jeb as the other entity. The ontology is quite small, you can see it by inspecting the 'war' file; in the directory WEB-INF/data there are the files for ontology schema + instances
  3. I'm getting a java version mismatch error!
    If you get this in the page where the ranking parameters can be changed, then the applet fails to load because the local machine's Java is a lower version than Java 1.5
  4. Can a different ontology be used?
    The 'war' file can be uncompressed for updating the contents of the WEB-INF/data directory in order to incorporate a different file for the ontology-schema, and ontology-instances. The web.xml file would have to be updated as well to reflect this change
  5. Which ontology is used?
    See schema + instances
