1 INFORMATION TECHNOLOGY Silvonen Semantic Web Tools Paula Silvonen VTT Information Technology

2 INFORMATION TECHNOLOGY Silvonen RDF Tools Topic Maps Tools Ontology Editors Ontology Software in Creating Multilingual Services Contents

3 INFORMATION TECHNOLOGY Silvonen RDF Tools RDF editors –for easy creation of metadata –HTML or RDF/XML –viewing, editing, and navigating in RDF data RDF parsers –translate the XML representation into RDF –make the RDF data utilizable for other applications –RDF/XML document => 3-tuple representation of the data model RDF database interfaces –storing and retrieving of data –different query languages

4 INFORMATION TECHNOLOGY Silvonen Topic Map Tools Ontopia tools: –Topic Map Engine for accessing and manipulating the constructs found in topic maps –Topic Map Navigator for building web-based topic map delivery applications –Full Text Search Integration –Omnigator - technology showcase and teaching aid

5 INFORMATION TECHNOLOGY Silvonen Ontology Editors - Motivation Knowledge-component reuse and sharing Easier construction and management of ontologies Easier analysis of ontologies Easier retrieval of ontological information by different export languages

6 INFORMATION TECHNOLOGY Silvonen Ontology Editors with Import Capabilities Protégé (RDF-Schema) OilEd (DAML+OIL) OntoEdit (Frame-Logic, OXML, RDF-Schema, OIL) WebODE (WebODE's XML, X-Carin) VOID (CML, EXPRESS, Ontolingua) JOE – Java Ontology Editor (KIF)

7 INFORMATION TECHNOLOGY Silvonen Ontology Editors with Illustrative GUI Protégé Cone WebODE CODE4 GKB-Editor JOE

8 INFORMATION TECHNOLOGY Silvonen Ontology Editors with Export Capabilities Protégé OntoEdit (Frame-Logic, OXML, Object-Relational Database Schema, Extended RDF-Schema, OIL, Document Type Definition) Cone (Prolog, html-tables, XML-Carin) WebODE (WebODE's XML, X-Carin, RDF(S), DAML+OIL, Prolog) JOE – Java Ontology Editor (KIF) VOID (CML, EXPRESS, Ontolingua)

9 INFORMATION TECHNOLOGY Silvonen Ontology Editors with Inference Engines OntoEdit - Frame-Logic inference engine & access tool,  Fact Description Logics inference engine OilEd - FaCT reasoner Cone - Prolog inference engine WebODE - Prolog inference engine

10 INFORMATION TECHNOLOGY Silvonen CONE: COnceptual NEtwork Software Adaptable relation types Definition of a concept Relationships between concepts The use of hierarchies Definition of the properties of a concept Major features: –WWW- and Java-based –Bridges to associate concepts in parallel models –Clustering to manage large ontology models –Inheritance of concept properties and relations –Instance support –Prolog used as description logic lang. –SQL-based repository of ontologies –Used by EC Mkbeem project for defining domain models, and by Briefs project for building business ontologies

11 INFORMATION TECHNOLOGY Silvonen MKBEEM Trials Customer’s Language Request Multi-Lingual Trading on a pan-European scale Updates a Multi-Lingual Multi-Cultural Catalogue B to C B to B U : Query: hupullinen keltainen toppatakki U : For a new product description: NLP-KRR Cataloguing U : I want to go to Helsinki next Monday. By the way could you propose me an finnish wintercoat for country skiing. MKBEEM :Fine, please select within our special travel package season offers. In addition we also display our selection of wintercoat from Ellos in Finland. Please make your selection. NLP Meaning extraction and generation. KRR Integration

12 INFORMATION TECHNOLOGY Silvonen MKBEEM: Please, give more properties for the winter jacket CONE in Language Processing Content provider cataloguing of product descriptions Content provider cataloguing of product descriptions " Toppatakki. Muhkea malli, olkapäissä vahvikkeet. Painonapeilla kiinnitetty huppu, jossa joustava nyöri. Vetoketjun alla suojalista. Kaksi kannellista taskua... Meaning extraction Machine translation Dialogue processing Meaning extraction Machine translation Dialogue processing End-user: Information request I want a jacket made of wind-proof material to be used on a winter holiday. Bright colours and preferably with a hood "Toppatakki. Muhkea malli..." "Quilted jacket. Puffy model with reinforcements on the shoulder..." concept(X,quilted jacket), model(X,puffy), part(X,Y,reinforcement), property(Y,Z,hihat)... "Toppatakki. Muhkea malli..." "Quilted jacket. Puffy model with reinforcements on the shoulder..." concept(X,quilted jacket), model(X,puffy), part(X,Y,reinforcement), property(Y,Z,hihat)... HL processing Product ontologies... Multilingual ontological product catalogues

13 INFORMATION TECHNOLOGY Silvonen Conclusions Tools for easier construction and management of Semantic Web elements Knowledge-component reuse and sharing Multilinguality through ontologies
