Title: | WiKi’mantics: interpreting ontologies with WikipediA |
Authors: | LAKSHMI K.S |
Keywords: | Semantics – Semantics approximation, Ontology engineering, WikipediA |
Issue Date: | 26-May-2011 |
Abstract: | The main task of ontology based Semantic Web is finding the accurate semantics hiding beneath
the superficial representation of ontological entities. This, however, is not an easy task due to the
ambiguous nature of semantics. There is a lack of systematic engineering method to guide how
we comprehend semantics. Even though precise logic formulae can be used as the canonical
representation of ontological entities, understanding of such formulae may vary. A feasible
solution to juxtapose semantics interpretation is to reflect human cognitive variations. For this,
an approximation of semantics using sets of words/phrases is done, referred to as WiKimantic
vectors. These vectors are emerged through a set of well-tuned methods gradually surfacing the
semantics that remain implicit otherwise. Given a concept, we first identify its conceptual niche
amongst its neighbours in the graph representation of the ontology. Natural language
paraphrases of the isolated sub-graph are then generated and this textual description is
projected upon a large document repository. WiKimantic vectors are then drawn from the
document repository. |
