Building a DNS Ontology using METHONTOLOGY and Protégé-2000

Abstract

The Domain Name System (DNS) is an essential part of the Internet software infrastructure. Unfortunately, although DNS is so important to network operation today, rather few DNS administrators have the expertise to do the jobs well. Due to the complex and distributed nature of the DNS systems, we could often find lots of poorly performed DNS servers on lots of Internet sites. In this paper, we study the problem of building a DNS ontology from scratch using the METHONTOLOGY methodology and the Protégé-2000 system. Ontologies are becoming an important mechanism to build information systems. The advantages include the sharing of knowledge, the re-use of knowledge, and the better engineering of knowledge-based systems with respect to acquisition, verification and maintenance. To help extract knowledge from experts and construct the DNS ontology, we propose an efficient knowledge acquisition algorithm, DNS Ontology Construction Algorithm, to fast conceptualize DNS domain knowledge. This DNS ontology can then be used as a basis for some applications to enhance the operation, planning and management of the DNS systems.
