  16. Content • Brief introduction of WHU&SKLSE • Education and Experience in Higher Education • Research Interests • Ontology management and sharing • Context acquisition and context driven web service selection • Intelligent learning environment • Collaboration with TWC

  17. Ontology management and sharing

  18. Motivation • Ontology provides common basis for the interoperation between information resources. • When the number of ontology increases dramatically, we need efficient mechanism to organize and manage them. • Three basic problems for ontology management • Ontology Registration • Ontology Evolution • Ontology Mapping

  19. ISO/IEC19763-3 (1st edition) • 2002-2007, China, Japan, Korea, US, UK, Canada • Obstacles to ontology-based interoperation • Problem1 • Each ontology is developed independently and evolves autonomously. • Problem2 • Ontologies are described in several languages, sometimes with different names for same things in UoD or with the same name for different things in UoD. • ISO/IEC19763-3 aims to solve these problems, providing a general registration framework of ontologies.

  20. Scope of ISO/IEC19763-3 (1st Edition) MFI Ontology registration: ISO/IEC 19763-3

  21. Metamodelfor Ontology Registration

  22. Reference Ontology & Local Ontology • Reference Ontology • Published by Standard Organizations • Relatively Stable • Local Ontology • Ontologies constructed to meet the specific requirements of particular information systems • Some content originates from RO • With some modification • Some new content added

  23. Ontology_Whole----Ontology_Component----Ontology_Atomic_ConstructOntology_Whole----Ontology_Component----Ontology_Atomic_Construct • Ontology_Whole : an abstract metaclass that designates an ontology and contains the associated administrative information. • Ontology_Component: an abstract metaclass that designates a sentence contained in an ontology and contains the associate administrative information. • Ontology_Atomic_Construct: an abstract metaclass that designates a non-logical symbol that is used in a sentence and contains the associated administrative information.

  24. Reuse of ontology_components and ontology_ atomic_ constructs LO１ RO2 RO1 consist_of ROC1 LOC２ ROC4 ROC3 ROC2 use LOAC１ ROAC4 ROAC3 ROAC2 ROAC5 ROAC1 ROx, LOy: Reference_ or Local_Ontology ROCx, LOCy:Reference_ or Local_Ontology_Component ROACx, LOACy: Reference_ or Local_Ontology_Atomic_Construct

  26. Manufacturing Software Component Repository based on ISO/IEC 19763-3 • Background • Since 2004 • Main collaborator: KaiMu Software Company( The major CAD Software provider in Central China) • Wanted: Create CAD applications in a quicker manner, Streamline the communication between users and software engineers • Our proposal :Ontology Based Software Component Repository • Use ontologies to annotate software component • Use ontologies to facilitate the communication between users and software engineers. • Use ISO/IEC 19763-3 to promote the semantic interoperation between CAD systems

  29. Application in more than 240 companies in China ★ Including 10 top 500 companies 29

  30. On-Going Research: Application of ISO/IEC 19763-3 in Eco-Informatics Domain • Since 2007 • GEMET • General Multilingual Environmental thesaurus • Co-dev by EEA and EPA • Under the management of EIONET （European Environment Information and Observation Network） • Has been widely applied in many information systems in EU, US and UN. • With the joint invitation from EEA, EPA, Wuhan University participated the GEMET project with support from the Ministry of Environmental Protection(MEP) of China.

  31. Work in Progress • Translate the terms and explanations in GEMET into Chinese • Compare the Chinese Version of GEMET with corresponding national standards • Build GEMET ontology • Apply it in some systems designated by MEP Share some of China's environmental information on the web Use ISO/IEC 19763-3 to manage the GEMET ontology and the other ontologies in environment domain

  32. ISO/IEC 19763-3(2nd Edition) • 2007-2010 ,China, Japan, Korea, US, UK, Canada • Basic_Model & Evolution_Model • Points in Basic_Model: • New Classification of Ontologies: Registered Ontology Whole & Unregistered Ontology Whole • Registered Ontology Whole: Reference Ontology & Local Ontology • Authoritative_Extent: a metaclass whose instances indicate authoritative extent and compose a partially ordered set in terms of the reference "lessThanOrEqualTo". • Unregistered_Ontology_Whole < Local_Ontology < Reference_Ontology

  33. Basic_Model

  34. ISO/IEC 19763-3 (2nd Edition) • Points in Evolution_Model: • Due to the generality of ISO/IEC 19763-3 ， techinical details of specific languages or platforms are out of the scope. • So the evolution of ontology can only kept with Registered_Ontology_Whole_Evolution, Registered_Ontology_Component_Evolution and Registered_Ontology_Atomic_Construct_Evolution

  37. Context acquisition and context driven web service selection

  38. Motivation—Difficulty of Web Service Selection（1/2） ? B3 A1 B3 B3 A1 A1 B3 A1 A1 A1 A1 A1 A2 A4 A1 A2 A2 A4 A4 A1 A1 A2 A4 A2 A1 B3 A1 B3 A1 B3 B3 A1 A1 A1 A4 A1 A1 B3 A4 A1 A1 A1 A1 A4 A1 B3 A1 A1 A2 A4 A1 A1 A1 A1 A4 A1 A4 B3 A2 A4 A1 B3 A1 A1 A1 A1 A4 A4 A2 A1 A2 A1 B3 A2 A4 A2 A1 A2 A1 A1 A1 A1 A1 A1 A1 A1 A4 A2 A1 A4 A1 A1 A1 A1 A4 A2 A2 A1 A4 A1 A4 A1 A4 B3 A2 A1 A1 A4 A1 A1 A2 A4 A2 A1 A2 A2 A4 A1 B3 A4 B3 A1 A2 A1 A1 A2 A4 A4 B3 A1 A1 A1 A1 A1 A1 A1 B3 B3 A1 B3 A1 A2 B3 B3 A1 A1 A2 A1 A4 A2 A4 A4 A1 A1 A1 A1 A4 A1 A1 A1 A4 A2 A2 A4 A4 A1 A4 A1 A4 A1 A1 A2 A1 A4 A1 A2 A1 A1 A1 A2 A2 A1 A4 A1 B3 A1 A1 B3 B3 A1 A1 B3 A1

  39. Motivation—Difficulty of Web Service Selection(2/2) • In the era of attention economy, it is unrealistic to ask the user to input more and more explicit requirements. • We need effective methods to capture user's implicit requirements, for which context has always been regarded as the main source. • User’s requirements=Explicit requirements+ Contextual requirements • So it is of great importance to study the context acquisition issue and context driven web service selection problem.

  40. Context • Many definitions • Kernel Concepts: Time and Space • Low Level Context and High Level Context

  41. Relationship between context and domain models Domain Ontology Repository Inference High Level Context Low Level Context Role Goal Process Semantic Annotation Web Service Repository

  42. Accomplishments • A method for context driven WS selection • RGPSframework for domain modeling • Context box—a tool for context acquisition

  43. Relationships in RGPS • Relationships between Role and Goal • Roles take charge of corresponding role goals • An actor prefers his personal goal • Relationships between Goal and Process • Processes achieve functional goals • Processes contribute to the fulfillment of nonfunctional goals • Relationships between Process and Service • A service realizes a process R G P S
