Hendrik introduction into meta data model 2010-06-20

  1. 1. Introduction <ul><li>Meta-Data Model for Ontology Mapping Management </li></ul>
  2. 2. 1. Character Phase (1/2) <ul><li>Target and the source ontology are identified: </li></ul><ul><li>Ontology Name: a label for the ontology Ontology on Animals </li></ul><ul><li>Ontology Source: Where can I find the ontology file? www.wikipedia.org/animal.owl </li></ul><ul><li>Ontology PSI: Unique identifier </li></ul><ul><li>www.ontologies.org/animal </li></ul><ul><li>Ontology creation date: 2010-05-04 </li></ul><ul><li>Ontology author: name:Hendrik, email: [email_address] </li></ul>
  3. 3. 1. Character Phase (2/2) <ul><li>Target and the source ontology are characterizes: </li></ul><ul><li>Ontology language: Format of the ontology OWL DL, RDF </li></ul><ul><li>Ontology author: Who created the ontology name:Hendrik; organisation: TCD email: [email_address] etc. </li></ul><ul><li>Ontology size: How big is the ontology 5 classes, 10 individuals </li></ul><ul><li>Ontology style: What does the ontology look like deep hierarchy , flat hierarchy, network </li></ul>
  4. 4. 2. Matching Phase (1/2) <ul><li>Describes the method used to identify the candidates: </li></ul><ul><li>Method: How were the candidates found? manual selection or automated algorithm </li></ul><ul><li>Date of selection: When was selection performed 2010-05-06 </li></ul><ul><li>Describes the manual selection : </li></ul><ul><li>Selectors: Who did the selections? Hendrik, Andre, Declan (contact details) </li></ul><ul><li>Selectors background: relevant details about selectors Selectors had experience in Semantic Web </li></ul><ul><li>Selection process: details about the selection process Selectors analyzed all ontology elements Selectors group equal elements based on name similarity </li></ul>
  5. 5. 2. Matching Phase(2/2) <ul><li>Describes the automated matching: </li></ul><ul><li>Algorithm name: human-readable label String comparison </li></ul><ul><li>Algorithm implementation: org.jena.stringComparsion </li></ul><ul><li>Selection process: details of selection process Matching based on string similarity </li></ul>
  6. 6. 3. Mapping Phase (2/2) <ul><li>Describes the mapping context: </li></ul><ul><li>Mapping objective: What is the purpose/aim of the mappings? Enable knowledge exchange between ontologies </li></ul><ul><li>Mapping requirements: What rules have to be followed? Do not map product ids </li></ul><ul><li>Mapping context: What is the context? Mapping is created for Wikipedia.de </li></ul><ul><li>Mapping is used for a demonstrator </li></ul><ul><li>Describes the mapping process : </li></ul><ul><li>Mapping process: details about the mapping process Confirm mapping with similarity rating of > 0.5 % </li></ul><ul><li>Date of mapping: When was selection performed 2010-05-06 </li></ul>
  7. 7. 4. Execution Phase <ul><li>Describes the application of the mapping: </li></ul><ul><li>Mapping format: INRIA RDF </li></ul><ul><li>Mapping users: Known users of the mappings Hendrik Thomas </li></ul><ul><li>Application using mapping: Known application which used the mappings Wikipedia.de/mapMe </li></ul>
  8. 8. 5. Management Phase <ul><li>Describes the sharing of the mapping: </li></ul><ul><li>Source of the mapping file: www.mapme.org/m.rdf </li></ul><ul><li>Hashkey: unique key of mappings 23434534646456456 </li></ul><ul><li>LastChange: 2010-06-03 </li></ul><ul><li>Change notification: www.mapme.org/changes.rss </li></ul>
