A lookup index for Semantic Web resources

Abstract. Developers of Semantic Web applications face a challenge with respect to the decentralised publication model: where to find statements about encountered resources. The “linked data ” approach, which mandates that resource URIs should be de-referenced and yield metadata about the resource, helps but is only a partial solution and not followed widely. We present a simple lookup index that crawls and indexes resources on the Semantic Web. Our index allows applications to automatically retrieve sources with information about a certain resource. In contrast to more feature-rich Semantic Web search engines, our index is limited in scope and functionality and is therefore simple, small, and scalable.
