In order to retrieve meaningful information, Semantic web is the need of the hour. For developing the appropriate semantics, a good ontology has to be created. There are various ontology editing tools available in the market and much analysis on them has already been done so far. This paper shows the analysis of some latest ontology tools (TODE, OwlGrEd, Odase, OntoStudio 3.1) available both as desktop and online versions and compares it with the latest version of most popular tool Protégé 5.0. The analysis is done on the basis of features like architecture, storage, interoperability, library and GUI design. The result of the analysis is explored for each domain like E-government, tourism, transport, healthcare, etc. and ensures more understanding of these tools with respect to every domain. KEYWORDS: Ontology Tools, Ontology Development, Protégé, OwlGrEd, Odase, TODE INTRODUCTION The semantic web is considered to be a mesh of various inter-connected links that offer information in World Wide Web. The main target of creating a semantic web is to have an automated retrieval of information using these links which should be easily processed with machines. The Semantic web use ontologies to create such automatic links and provide knowledge representation for a particular domain. Hence, Ontology engineering has become a prominent field inside knowledge management community. Creating these ontologies require the use of various ontology editing tools. While creating a new ontology for a specific domain, we often try to figure out which tool are the easiest, simplified and give the best support for ontology creation. This survey paper will answer most of such questions and will help in analyzing various ontology editing tools. But first, we see a brief introduction of few important terms. Semantic Web Semantic Web as described by Tim Berners Lee himself is an extension of the World Wide Web that talks about more structured data in the form of a mesh of interconnected links. These links make the Web more intelligent and intuitive about users’ needs. Here the meaningful information is automatically gathered and reprocessed so that other machines may also use the information. Hence Semantic web in its true sense is much related to the meaning of data rather than its structure. Semantic Web has quite few names of its own like Web of Data, Web 3.0, or The Linked data Web. The semantic web in itself is distributed and heterogeneous and aims at providing reusability of information in the form of semantic links. Also semantic web offers various benefits like knowledge sharing, web automation, reducing redundancy, etc. [12]. Web Ontology The semantic web is implemented using the Web ontology which describes information in the form of formal explicit description of concepts in a given domain. Ontology includes a set of distinct instances of classes that forms a knowledge base. Neches [13] who defined Ontology for the first time described it as “Ontology defines the basic terms and the relations that include the vocabulary of a specific area, in addition to the rules to combine terms and relations to define extensions to the vocabulary”. Ontology is created to give a concrete
