Implementation details• Server
– REST services implemented in Java for generating (SPARQL via Virtuoso) the EKP-based summarization of an entity in RDF
• Client– Ext JS for ui widgets– The JavaScript InfoVis Toolkit for the visualization of the
graphs– Ajax for querying third parties
• Twitter API• GoogleNews API
• Apache Stanbol– Named Entity Recognition– Identity Resolution to DBpedia
