Description:
Swoogle is a crawler-based indexing and retrieval system for the Semantic Web documents - i.e., RDF or OWL documents. It analyzes the documents it discovered to compute useful metadata properties and relationships between them. The documents are also indexed by using an information retrieval system which can use either character N-Gram or URIs as terms to finnd documents matching a user's query or to compute the similarity among a set of documents. One of the interesting properties computed for each Semantic Web document is its rank - a measure of the document's importance on the Semantic Web.

Swoogle is off line for a day or two. We discovered that our Swoogle server (pear) was compromised. (Yet another PHP-Nuke vulnerability.) We have a plan to bring it back up in a more secure configuration with the database behind a firewall and only the web interface exposed to the elements. A consequence is that only the official URL, HTTP://SWOOGLE.UMBC.EDU/, will work. It's a jungle out there. See our research blog at http://ebiquity.umbc.edu/v2.1/blogger/ for updates.
