document: CS AKTive space : representing computer science in the semantic web We present a Semantic Web application that we callCS AKTive Space . The application exploits a wide range of semantically heterogeneousand distributed content relating to Computer Science research in theUK . This content is gathered on a continuous basis using a variety of methods including harvesting and scraping as well as adopting a range models for content acquisition . The content currently comprises aroundten million RDF triples and we have developed storage , retrieval andmaintenance methods to support its management . The content is mediated through an ontology constructed for the application domainand incorporates components from other published ontologies . CS AKTive Spacesupports the exploration of patterns and implications inherent in the content and exploits a variety of visualisations and multi dimensional representations . Knowledge services supported in the applicationinclude investigating communities of practice : who is working , researching or publishing with whom . This work illustrates a number ofsubstantial challenges for the Semantic Web . These include problems of referential integrity , tractable inference and interaction support . Wereview our approaches to these issues and discuss relevant related work .
