Falcons Semantic Web Search Engine
http://ws.nju.edu.cn/falcons/objectsearch/index.jsp

Falcons is a Semantic Web search engine. It provides keyword-based search for objects, concepts (classes and properties), ontologies, and RDF documents on the Semantic Web. Just enter one or several keywords describing the object(s) or concept(s) you are interested in. Separate keywords with the space character, and put phrases in double quotes. Boolean queries are also supported. In Object Search, you can navigate a class hierarchy to refine your search. In Concept Search, you can select any vocabulary recommended to refine your search. You can also restrict your search to only classes or properties. This has been added to the tools section of Research Resources Subject Tracer™ Information Blog.
