  1. The ARTEMIS prototype for the construction of reconciled views based on affinity evaluation and interactive clustering S.Castano, A.Ferrara, G.Ornetti Università di Milano V.De Antonellis, M.Melchiori Università di Brescia

  2. The ARTEMIS tool environment architecture Access to external data CORBA Object CORBA Interaction Wrappers ARTEMIS Mediator Clustering ODLi3 Name affinity evaluation Global affinity evaluation X-Formalism to ODLi3 Wrapper Structural affinity evaluation Unification Interschema properties Thesaurus ODLI3 to X-Formalism Wrapper Extensional affinity evaluation ARTEMIS GUI Affinity evaluation

  3. The ARTEMIS/MOMIS interaction Access to external data CORBA Object CORBA Interaction Name affinity evaluation Affinity evaluation ARTEMIS Mediator Interschema properties Thesaurus Structural affinity evaluation Global affinity evaluation Clustering Extensional affinity evaluation MOMIS mediator ODLi3 Clusters Common Thesaurus

  4. The ARTEMIS functionalities Wrapping semistructured source schemas into ODLi3 representation Loading ODLi3 source schemas Set-up/import of a thesaurus of terminological relationships and inter-schema properties for schema matching Affinity-based analysis of source schemas (combination of several affinity coefficients) Clustering of schema elements and construction of the affinity tree Interactive selection of candidate clusters and cluster storage Interactive creation of global classes and associated mapping rules out of clusters through unification rules

  5. ARTEMIS Demo New functionalities for XML datasource management X-formalism model, for conceptual representation of XML schema descriptions (e.g., DTDs) Wrapper module for DTD-to-X-formalism and for X-formalism-to-ODLI3 translations Unification rules for XML datasources Importation of the Common Thesaurus provided by MOMIS

  6. The ARTEMIS workspace The workspace GUI allows the designer to define the integration process settings

  7. Wrapping XML datasources: X-formalism-to-ODLi3 X-formalism specification ODLi3 specification

  8. Importation of the Common Thesaurus The ARTEMIS representation of relationships in the Common Thesaurus

  9. The global affinity evaluation Global Affinity Name Affinity Structural Affinity

  10. Extensional relationships definition Intensional relationships Extensional relationships Source view

  11. The extensional affinity evaluation

  12. Interactive clustering: selection of candidate clusters Candidate clusters

  13. Interactive clustering: hierarchical view Interactive definition of the name of a global class Selected class description Class in the cluster Clusters representation

  14. Visualization of global classes Selected global class description Global classes representation

  15. Mapping table representation Global attributes Global class Source values
