NEWS (News Engine Web Services)

1. Building an Ontology for NEWS ApplicationsNorberto Fernández-García, Luis Sánchez-Fernández Telematic Engineering DepartmentCarlos III University of Madrid[berto, luiss]@it.uc3m.es NEWS Ontology NEWS (News Engine Web Services) • USAGE SCENARIO REQUIREMENTS: • Intended Usage: • News categorization taxonomy • News annotation vocabulary • Axioms for intelligent query component • Compatibility with journalism standards: • News representation standards (NewsML, NITF) • News metadata standards • Fast processing (news freshness) • Range of Contents (almost everything in the world!) • Compatibility with Ontology Standards (RDFS, OWL) • FIRST NEWS ONTOLOGY PROTOTYPE: • Relies on NITF as news representation standard. • Three main modules: • News Item Categorization SRS IPTC standard. • Management Metadata  Based in DC, PRISM, • management metadata in NITF and requirements • from EFE and ANSA. • Content Annotation Metadata Generic Top-level with • basic entities. Based in NITF inline annotation tags and • story W’s  When, Where, Who, What, etc. • NEWS ITEM METADATA EXAMPLE: • See: http://www.it.uc3m.es/news-int/example.rdf http://www.news-project.com PARTNERS: • OBJECTIVES: • Define ontologies for the news industry, using • standards as OWL or RDFS. • Use Web Services technologies in order to implement • interoperable components which can be integrated • into the news agencies’ workflow: • An ontological annotation component to produce • automatically annotations for newswires. • Intelligent, reasoning-based, query component with • multilingual and multimedia capabilities. • Facilitate definition of personal interest profiles • Adapt news content delivery to different plattforms (eg., mobile phones). <NewsItemMetadata rdf:ID="http://www.efe.es/items/Metadata/Met-NITF-VI9222"> <hasNewsItem rdf:datatype="&xsd;anyURI">http://www.efe.es/items/NITF/VI9222</hasNewsItem> <hasTitle rdf:datatype="&xsd;string">Cámara Vasca condena "manipulación informativa" de Gobierno de PP.</hasTitle> <hasMainHeadline rdf:datatype="&xsd;string">P.VASCO-ATENTADOS MADRID</hasMainHeadline> <hasSubHeadline rdf:datatype="&xsd;string">Cámara Vasca condena "manipulación informativa" de Gobierno de PP</hasSubHeadline> <!-- Values from IPTC Topic Sets --> <hasMediaType rdf:datatype="&xsd;anyURI">urn:newsml:iptc.org:20001006:topicset.iptc-mediatype:3#Med1 </hasMediaType> <hasObjectType rdf:datatype="&xsd;anyURI">urn:newsml:iptc.org:20001006:topicset.iptc-newsitemtype:4#nit01 </hasObjectType> <hasAttribute rdf:datatype="&xsd;anyURI">urn:newsml:iptc.org:20001006:topicset.iptc-genre:5#A001 </hasAttribute> <!-- Category of news item --> <hasSubjectReference> <hasSubjectIdentifier rdf:datatype="&xsd;anyURI">http://www.news-project.com/ontology-alpha#sr02000000 </hasSubjectIdentifier> <hasSubjectFullName rdf:datatype="&xsd;string">Crime, Law and Justice</hasSubjectFullName> </hasSubjectReference> <hasKeyword rdf:datatype="&xsd;string">P.VASCO-ATENTADOS MADRID</hasKeyword> <hasLanguage rdf:datatype="&xsd;language">es-ES</hasLanguage> <hasIdentifier rdf:datatype="&xsd;string">VI9222</hasIdentifier> <hasAuthorshipInfo> <hasAuthor rdf:datatype="&xsd;string">efea0840/efea0828</hasAuthor> <hasCodedAuthor rdf:datatype="&xsd;string">O99ZqLwKrw29ZqLwKp23nwJ</hasCodedAuthor> <hasCreationTime rdf:datatype="&xsd;dateTime">2004-05-07T11:26:00</hasCreationTime> <hasCreationLocation/> </hasAuthorshipInfo> <hasPriority rdf:resource=" http://www.news-project.com/ontology-alpha#EFE_priority_R"/> <hasRelevance rdf:resource=" http://www.news-project.com/ontology-alpha#EFE_relevance_C"/> <hasStoryTime rdf:datatype="&xsd;date">2004-05-07</hasStoryTime> <hasStoryLocation rdf:datatype="&xsd;string">Vitoria</hasStoryLocation> <hasAnnotation> <hasEntity rdf:datatype="&xsd;anyURI"> http://www.news-project.com/ontology-alpha#City</hasEntity> <hasStartPoint rdf:datatype="&xsd;anyURI"> http://www.efe.es/items/NITF/VI9222#xpointer(//body.content/p[1]/text()/point()[position()=189]) </hasStartPoint> <hasText rdf:datatype="&xsd;string">Madrid</hasText> </hasAnnotation> </NewsItemMetadata> NEWS INTENDED WORKFLOW: NEWS is funded as project FP6 001906 by Semantic-based Knowledge Services ISWC 2004 – Hiroshima (Japan)
