Extending SKOS: A Wikipedia-Based Unified Annotation Model for Creating Interoperable Domain Ontologies

摘要

Interoperability of annotations in different domains is an essential demand to facilitate the interchange of data between semantic applications. Foundational ontologies, such as SKOS (Simple Knowledge Organization System), play an important role in creating an interoperable layer for annotation. We are proposing a multi-layer ontology schema, named SKOS-Wiki, which extends SKOS to create an annotation model and relies on the semantic structure of the Wikipedia. We also inherit the DBpedia definition of named entities. The main goal of our proposed extension is to fill the semantic gaps between these models to create a unified annotation schema.
