A. The multilingual semantic wiki scenario

A. The multilingual semantic wiki scenario

The new workpackage 11 aims to use GF to extend AceWiki to a multilingual constrained language semantic wiki. Like the original AceWiki, it allows users to express in natural language logical constraints that are subject to automated reasoning. AceWiki already has facilities for extending the lexicon. A subset of the constraints expressible in ACE are interatranslatable with the OWL ontology language. In the scenario envisaged here, the multilingual semantic wiki works as a tool for extending a special domain ontology through natural language verbalization. This platform supports the scenario where a special domain ontology and its verbalizations are extended simultaneously.

In one natural scenario, a special domain expert expresses the constraints in unconstrained natural language as comments in the wiki. One or more ontology experts refine the description into a set of simpler statements in a constrained subset that maps to OWL, using already existing ontologies as base and creating the missing ontology resources and their verbalizations in a common natural language using the lexicon editor. The domain experts can test the conceptualization by asking questions of the ontology. The questions are answered in natural language using the wiki's reasoners. When the coverage of the ontology and its verbalization in the chosen language/s is sufficient, the lexicon is extended for the remaining languages, using existing term ontologies as a base, by target language experts.
