WP4: Knowledge Engineering

  • knowledge representation infrastructure (D4.1, by Ontotext);
  • aligned semantic models and instance bases (D4.2, by Ontotext and UHEL);
  • two-way grammar-ontology and NL (Natural Language) to ontology interoperability (D4.3, by Ontotext and UGOT).

    • M1-M6 plan

    • all partners send informal answers of the questions above & anything additional that has been missed in the questions (questionnaire)[/node/896]
    • decide on the best server location (on site / rented)
    • Ontotext to provide a description of what is the planned initial infrastructure for KE
    • Ontotext to describe more about the LOD data sets and give the LDSR link
    • UHEL to indicate their ideas on the KE WP, data sets and participation
    • provide examples of entity descriptions in WKB
    • first attempts on NL queries based on the WKB; put examples of the entity description constructs and then decide next steps with UGOT/UHEL;
    • discuss feasibility of creating a NL interface for SPARQL (or a subset)
    • provide examples of entity descriptions in WKB
    • KE infrastructure in place
    • decide on initial data sets with the partners; consider one or many instances
    • KE infrastructure loaded with initial data sets
    • navigation and search web UI over KEI
    • results of the first experiences on ontology to grammar interoperability
    • M4.1 - Knowledge representation - Retrieval access provided infrastructure to the consortium
    • report for M1-M6
    • plan for M6-M12

    M6-M12 plan

    • analyze the needs of autocompletetion and implement scalable solution for it
    • work on transformation from natural language to sparql
    • report for M6-M12
    • plan for M6-M12

    M12-M18 plan

    • experiment with different ontologies
    • write D4.2
    • work on verbalization of the results from the semantic repository search
    • finalize the D4.3 prototype
    • report for M12-M18
    • plan for M12-M18

    M18-M24 plan

    • support the work on other workpakages in the sphere of grammar-ontology interoperability
    • report for M18-M24

    Process & General Considerations

    • we'd like all info to be available on the wiki, incl. notes, decisions, status of the components, docs
    • SVN
    • consider a backlog for the entire project/ each WP
    • consider periodic development/delivery cycles
    • consider regular telecons/skype conferences - once a month at least
    • make application ideas backlog at the wiki

    Knowledge Engineering Infrastructure in place

    According to the plan http://www.molto-project.eu/node/858 the Knowledge Engineering Infrastructure has been realeased. It is accessible here. We have imported an exemplary initial data set containing information for different persons, organizations, locations.

    To execute a SPARQL query to the data set, click "SPARQL Query" and for exemple try the following query without the backslashes (\)

    prefix rdf:<\http://www.w3.org/1999/02/22-rdf-syntax-ns#> prefix rdfs:<\http://www.w3.org/2000/01/rdf-schema#> prefix prt:<\http://proton.semanticweb.org/2006/05/protont#> select distinct ?l where { ?s rdf:type prt:Organization ; rdfs:label ?l . }

    It should return the names of all organizations stored in the data set.

    The Knowledge Engineering Infrastructure could be extended with new data sets if new data sets are available, see http://www.molto-project.eu/node/858, http://www.molto-project.eu/node/896 and http://www.molto-project.eu/node/948.
