One of the major problems in the implementation ofNatural Language Processing (NLP) or MachineTranslation(MT) is a complete lexicon: the place wherethe systems information about words is stored. There aredifficulties in deciding what information should bestored in a lexicon and even greater difficulties inacquiring this information in proper form. OriNetsystem designed to incorporate multiple lexical databaseand tools under one consistent functional interface inorder to facilitate systems requiring syntactic, semanticand lexical information of Oriya language. We dividethe whole work into two independent task. One task isto write the source file that contains the basic lexicaldata and the content of those files are the lexicalsubstance of OriNet. Lexicographer did the major workof this task. In the second task was to create a set ofprograms those would accept the source files andprocessing it ultimately to display for the user. Thispaper describes an ongoing work on designing an ObjectOriented model for OriNet system. The technology ofObject Oriented programming in particular the richlibrary of classes and programming principles in whichJava offers. It also provides a convenient tool toconceptualise the process of OriNet system. Thistechnique also allows flexibility and extensibility of thesystem with more robustness.
