Abstract: I will describe a prototype Internet search engine for semantic web documents encoded in RDF and OWL. The system is intended to support human users as well as software agents and services. It consists of a database that stores document metadata, a web crawler that locates new and modified semantic web documents, components to compute useful document metadata and semantic relationships among the documents, a character ngram indexing and retrieval engine, and a web-based interface for querying the system. Among the properties we compute for each document is it's rank, a metric inspired by inspired by Google's pagerank attribute but adapted to the various relationships between semantic web documents. We will also present some very preliminary results summarizing the characteristics of the portion of the semantic web that our system has crawled and analyzed.
