Building Domain Ontology based on Formal Concept Analysis

Abstract

There has been a growing concern on ontology due to its ability to explicitly describe data semantics in a common way, independently of data source characteristics, providing a schema that allows data interchanging among heterogeneous information systems and users. Ontologies are currently being used for explicit representation of the domain knowledge. Ontology provides knowledge about specific domain that is understandable by both developers and computer systems and necessary for knowledge representation and knowledge exchange. Several works have been aimed to improve ontology technological aspects, like representation languages and inference mechanisms, and development method application Using existing taxonomical hierarchies are not enough for knowledge exchange or for informational retrieval. These may cause the problems in knowledge sharing. Therefore we need a better way to describe the concepts and relation for discovering new concepts and relations in ontology. This paper presents an approach of developing ontology for the movie review domain with Formal Concept Analysis (FCA) design.
