  22. MFI-New Parts under the Study http://www.tiu.ac.jp/org/forum-01/index.files/Page694.html

  23. Works in the Study • A Metamodel for Ontology evolution and maintenance are under discussions as a part of MFI-3 (2nd Edition of MFI-3) • A metamodel for the process registration (process ontology) is also discussed in the SC32WG2. OWL-S or PSL(ISO) are being investigated.

  24. Ontology Evolution(Candidate of 2ndED 19763 Part-3) Keqing He and Yangfang He, Wuhan Univ. China

  25. We need some measures to resolve the conflicts We need add class A, remove individual i… Possible conflict ! Domain experts Ontology engineer We need keep class B, individual i… Change Closure Consistency Closure Information system engineer Evolution Strategy Final Change Set Basic resolution provided by MFI-3 ontology

  26. Key Problems • How to registrate ontologies? • What kind of change can be identified and described by MFI-3? • How to realign the dependent ontologies during the evolution process? • How to keep the evolution information about ontologies

  27. Our Solution (1/2) • How to registrate ontologies? • What kind of change can be identified and described by MFI-3? • How to realign the dependent ontologies during the evolution process? • How to keep the evolution information about ontologies Kernel Model Change Model Constraint Model Change Propagation Model Evolution Information Model

  28. Our solution (2/2)

  29. Differences from DB Schema evolution “Ontology Evolution: Not same as the schema evolution” , Natalya F.Noy, Michel Klein • Ontologies are data too • Ontology themselves incorporate semantics • Class and instances can be the same • Etc.

  30. Comment at the Wuhan meeting • WD (Working Draft ) should be prepared by the NY meeting, July 2007.

  31. Process Registration(Candidate of a new part of 19763) Keqing He and Wang Chong, Wuhan Univ., China

  32. “process” & “process model” • Process is defined as • a set of work items, scheduled according to constraints, which all participate in fulfilling at a common purpose. [Breton and Bezivin 2001] • transformation of input to output. [ISO 1995] • one or more activities that occurs over a period of time in which objects participate. [ISO 18629] • Process model can be regarded as the product of process modeling.

  33. Taxonomy of Processes Domain specific processes -In house Business process (Accounting, AR/AP) -Between Enterprises (Collaboration) -Industrial specific: Healthcare, Manufacturing, • Software Process • Dynamic aspect  A part of an ontology • Ontology migration process • Registration process

  34. Type of Process Model PSL, Upper Ontology or Abstract Syntx Modeling Patters BPMN MIT HB Collaboration Notation Model Contents UN/CEFACT BCF Metamodel Methodology UML IDEF 3 EXpress CPFR, ARTS UMM

  35. Comparative Analysis

  36. Related work • PSL (ISO 18629) • a language enabling interoperability of process information among industrial applications. • IDEF-3 • captures process details. • BPMN • defines modeling notation for modeling business process. • BPEL4WS • provides a means of specifying the interaction of cooperating services. • OWL-s • define an ontology to describe the interface a service provides to the “outside world”. • only for Web Services • ……

  37. Process Ontology t1 t2 Ontology (t1) Ontology(t2) Process X Ontology(t2) = processX (Ontologyt(t1))

  38. Why we need MFI-5 • Web service • one of the important resources on the semantic web. • characterized with dynamic features. • Business process • interoperation and cooperation within/across the enterprises • MFI family focuses on the static resources on the web • MFI Core provides a very generic framework for various models. • MFI4Onto aims to the structure and semantics of ontology • A new part is needed to meet the requirements of dynamic resources (web services, business process etc.) on the semantic web • process model registration • process model integration with semantics • construction of customized services/process model

  39. Scope of MFI-5 (1/2) • Objective • Provide a metamodel to register process models, including business process model and web service. • Focus on the relationship between process model described with different process description languages, especially the composite process consists of subprocesses expressed in different languages. • Promote semantic interoperation between various process models on the semantic web. MFI-5 … PSL IDEF-3

  40. Scope of MFI-5 (2/2) • What to do • Structural information of process model • Which subprocesses are contained in process model • Which artifact participate in fulfilling the common purpose • Semantic constraints of process model • Semantic relation/contradiction between artifacts • Order • Mandatory sequence • Precondition and postcondition • User-defined constraints • …… • What not to do • Language specific details • Implementation level details

  41. MFI Core & MFI-5 From MFI Core

  42. Basic idea of MFI-5(1/2) • Base Model is proposed to register structure information of various process models • Goal: the purpose that should be archived by fulfilling the process model • Role: the actor who interact with the process • Artifact: the resources that participate in the process • Order: specifies the sequence of a composite process

  43. Base Model

  44. Basic idea of MFI-5(2/2) • Process Control Model is defined to record three kinds of control constraints in process models • Sequence control • Specify the sequence followed by the subprocesses • Object control • Restrict the semantic relations between artifacts and avoid possible semantic inconsistency • Support semantic interoperation between process models based on ontology • User-defined control

  45. Process Control Model

  46. OWL-S --Top level of the Process Ontology--

  47. Comments at the meeting • More research and investigation should be needed. • Is it premature to make it ISO standard? • Collaborative work with other group should be initiated.

  48. Requirements for DB Technologies

  49. What are needed in the Future
