This search engine is powered by SemSearch, which is designed for ordinary end users who are not necessarily familiar with domain specific semantic data, ontologies, or SQL-like query languages. It is implemented using Sesame as the underlying formal language query engine and Apache Lucene as the text search engine.

The query interface comprises three operations: i) the symbol ':', which specifies the type of the information the user is looking for, ii) the world 'and', which specifies the required keywords, and iii) the word 'or', which specifies optional keywords. An example query would be "workshop:wiki", which returns workshops about wiki.

Here is a list of generic query examples: paper; person; workshop;
