WP4 Knowledge engineering - M18

WP4's main task is to research the possibilities for interoperability between grammars, written in GF, and ontologies and to build a prototype demonstrating it.

During the period M12-M18 the work concentrated on refactoring and bug fixing of the prototype build earlier, on experimenting with bigger data sets, and on extending the functionality of the prototype. The main points can be summarized as follows:

• the infrastructure has been updated with latest versions of the semantic repository and tools - this was necessary because SPARQL 1.1 queries are supported by the newest version of the semantic repository Owlim.
• the set of the ontologies has been extended with dbpedia, geonames and other databases. - this task is important for re-usability of the prototype in the use cases WP6-WP8.
• analyzed the requirements of the verbalization of the results
• implemented a verbalization of the results - the current implementation generates automatically a GF abstract representation from the results and this abstract representation is matched from the GF abstract grammar and GF concrete grammar that are also build automatically from the ontology.
• add 4 more languages to the prototype - the current list of the languages for the prototype is: English, Finnish, Swedish, French, German and Italian.
• refactoring of the prototype GUI and internationalization.
• test and bug fixing the prototype for Deliverable D4.3
