  1. Motivation • Intelligent agents need knowledge and information. • Majority of content on the web remains in NL text. • SW can benefit NLP tools in their language understanding task Facts from NL NLP Tools Natural Language RDF/OWL WWW Semantic Web Text Images Audio video Ontologies Instances triples Web of documents Web of data structured information

  2. Provides RDF version of the news. Language Understanding Agents Motivation

  3. Ontological Semantics OntoSem is a Natural Language Processing System that processes the text and converts them into facts. Supported by a constructed world model encoded in a rich Ontology.

  4. Fact Repository Interface Language Processing Data Aggregators 1 11 2 OntoSem RSS Aggregator Ontology & Instance browser 3 4 News Feeds TMRs FR Text Search 12 RDQL Query 13 6 5 OntoSem2OWL Swoogle Index 14 9 Dekade Editor 7 OntoSem Ontology (OWL) Inferred Triples Semantic RSS 15 10 8 Knowledge Editor Environment TMR Semantic Web Tools http://semnews.umbc.edu

  5. Agent understandable news Provides RDF version of the news. http://semnews.umbc.edu

  6. Semantacizing RSS View structured representation of the RSS news story. Future versions would enable editing the facts and provide provenance information http://semnews.umbc.edu

  7. News stories are ontologically linked Find news stories by browsing through the OntoSem ontology. http://semnews.umbc.edu

  8. Tracking Named Entities Find stories about a specific named entity. http://semnews.umbc.edu

  9. Browsing Facts Fact repository explorer for named entity ‘Mexico’ shows that it has a relation ‘nationality-of’ with CITIZEN-235 Fact repository explorer for instance CITIZEN-235 shows that the citizen is an agent of ESCAPE-EVENT http://semnews.umbc.edu

  10. Querying the semanticized RSS RDQL Queries Provides structured querying over text converted into RDF representation. http://semnews.umbc.edu

  11. Semantic Alerts Alerts can be specified as ontological concepts/ keywords / RDQL queries. Subscribe to results of structured queries http://semnews.umbc.edu
