Ontology-like Resources in Construction


Celson lima cost action c21 belfast may 2006

CV

  • Working in European Projects since 1992

  • Researcher at CSTB, Sophia Antipolis, France (2001)

  • Doctoral degree in Electrical Eng.: New University of Lisbon, Portugal (2001)

  • Master degree in Mechanical Eng.: UFSC, Brazil, co-operation with FCT/UNL (1994)

  • Graduated Computer Science: UFSC, Brazil (1986)

  • Main areas of interest: KM, Standards and Interoperation (eBusiness), Coordination Systems, NOs


Outline

Outline

  • Background

  • Production Process

  • Some Examples

  • Where we are now

  • Challenges


1 background semantic resources

1. Background: Semantic Resources

  • SRs: Ontology-similar entities

    • Taxonomies, classification systems, thesauri, etc.

  • Sharing knowledge precisely

    • No ambiguity, accuracy

    • Interoperability

  • Likely to be integrated into Standards

  • Challenges dealing with SRs

    • Difficult to standardise, few SRs available for Construction

    • Creation process: time consuming

    • Semi-automatic generation, with human validation


1 background projects 1 3

1. Background: Projects(1/3)

  • Research Projects

    • eConstruct

      • Goal: e-procurement

      • Results: bcXML, bcBuildingDefinitions taxononomy + sw tools, multilingual capabilities (6 languages)

      • Operation: creation/publication/use of e-catalogues bcXML compliant

      • One single product: door, 3 000 elements

    • e-COGNOS

      • Goal: develop KM-tool ontology enabled

      • Results: e-CKMI, e-COSer, e-COGNOS Ontology

      • 15 000 concepts, OWL

      • Operation: support of KM functionalities


1 background projects 2 3

1. Background: Projects (2/3)

  • Research Projects

    • FUNSIEC

      • Goal: map Semantic Resources for Construction

      • Results: methodology + sw tools + mapping tables for ISO12006, IFC, e-COGNOS and bcXML

      • Operation: creation of mapping tables between 2 SRs

    • IFD: ‘observer’ (On-going initiative)

      • Goal: Define the way Construction should define and create « Construction objects » (library of)

      • Focus: Harmonisation of ISO 12006-3 (world wide)

    • ISO 12006-3 Family

      • LexiCon, Barbi: Library of « Construction Objects »

      • Focus: implement the ISO 12006-3

      • MultiLingual: Dutch, English, German, French, Norwegian


1 background projects 3 3

1. Background: Projects(3/3)

  • IFC: Industry Foundation Classes

    Vision

  • to provide a universal basis for process improvement and information sharing in the construction and facilities management industries

    Mission

  • to define, promote and publish a specification for sharing data throughout the project life-cycle, globally, across disciplines and across technical applications

    Set the Standard

  • for object-based data exchange and sharing of virtual buildings

    • International, industry-driven, cross-discipline

    • all data for the VIRTUAL BUILDING MODEL

      Deliverables

  • Information for Construction (IFCTM and ifcXMLTM)

    • goes beyond CAD information

    • involves non-geometric applications

    • includes operation of buildings

    • handles physical things, process, general ideas and relationship among them

3. Some Examples

  • eConstruct

  • Design, implement and disseminate a new communication technology tailored to the BC needs

  • Target: "eConstruction"

    • Internet-based, commerce-oriented transactions, Business-to-Business (B2B) or Business-to-Consumer (B2C) operations

  • Integration and data exchange between application tools in the B&C Market

  • bcXML: Building and Construction eXtensible Mark-up Language

  • Prove its usefulness: bcXML Reference Architecture

  • Software Clients, Kernel components, and Creation Tools

    • Bigger ontology = better ontology?

    • Standards: good idea, interesting approach, but …

    • End users prefer to stick with their own vocabularies

    • Ontological indexes >= statistical ones

      • Ontology: they don't want to hear about it! However …

      • It would be great to have richer indexes!

      • They have to be convinced that the ontology can really help them

    • Advanced users: willing to do more in order to get more
