Ontology management and

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

METAMODEL FOR ONTOLOGY REGISTRATION

22

REFERENCE ONTOLOGY & LOCAL ONTOLOGY

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

Reference Ontology• Published by Standard Organizations• Relatively Stable

23

ONTOLOGY_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.

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

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

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

Translate the terms and explanations in GEMET into Chinese

Compare the Chinese Version of GEMET with corresponding national standards

Build GEMET ontology

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

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.

APPLYING WEB 2.0 TECHNIQUES IN PBL

PBL ： Problem Based Learning

53

PROBLEM BASED LEARNING

In PBL, cases are used to help students understand the meaning of concepts.

Teachers should select cases according to a give concept set.

Normally, the chosen case set should cover all the concepts in the concept set.

54

OUR METHOD (1/3)

Use Wiki techniques to help teachers to build the knowledge system of a specific course, like Orthopedics.

Use the Orthopedics ontology to annotate cases.

Select appropriate case set according to the given concept set.

55

OUR METHOD (2/3)

In the classes, teachers can easily navigate between the concepts with the support of Orthowiki.

When some concepts are not well understood, they could be added to the concept set of the next class, and the cases could be reselected accordingly.
