Some suggestions regarding Ontology Search Engine

Hi Arthur There is nothing explicit that I could find on their performance comparison. Current OntoSearch UI is completely different than the one mentioned in this paper. You can check it at http://www.ontosearch.com/. And WI OntoSearch isn't accessible. In the evaluation section- in my opinion the number of results for before filtering kind of deals with OntoSearch as it was based on simple keywords just like a normal google search engine. And after applying the algorithm ie in WI OntoSearch the number of results reduced as it filtered out irrelevant ontologies.
