Abstract:
Ontology is a specification of conceptualization. This paper introduces an environment to develop
semantic web applications. This environment integrates a lot of tools such as an editing capability, logic
reasoner and semantic search engine. Design and implementation of a generalized ontology editor is presented
in this paper through which the user may create, edit, validate, open, search (local and global), or visualize an
ontology or an instance file. The user may edit an instance to be stored either in a RDF/XML file, OWL/XML,
xml knowledge base or other formats. The user may present the ontology hierarchy and the knowledge base in
a tabular form. The environment provides an interface through which the user may consult the knowledge base
by SQL-like statements. It also allows the user to map ontology to another. It also introduces the virtualization
concept providing a mechanism to categorize the ontology instances based on given ontology features. It also
provides logic reasoner so we may check the truth of an instance against a specific knowledge base. A semantic
search engine is also available either locally or globally.
