Implementation of the dynamic semantic ontological framework

Abstract:

In this work the Dynamic Semantic Ontological Framework (MODS) specified in [1] is implemented. MODS formalizes and interprets queries made by users in natural language. For this, MODS transforms the query into a format of representation of the meaning of the Query, which is based on an ontology language (OWL) in order to be used by the Semantic Web, using the different components that comprise it. MODS is composed of a lexicon, a linguistic ontology, an ontology of tasks and a domain ontology. Thus, MODS uses mechanisms of the ontological semantic and of the natural language processing, to process the user queries. Specifically, this article defines, using ontologies on descriptive logic, each component of MODS. In addition, the ontological implementation of each component is carried out, using in each case additionally specific libraries. For example, OpenNLP is used by the ontology of tasks for the words processing, the Jena Framework is used by all the ontologies of MODS to handl them, and Pellet is used as the reasoning mechanism in the ontologies of MODS. Finally, experiments are presented using this implementation of MODS.
