Combinatorial Category Grammar is (CCG) a lexicalized grammar formalism which is expressed by syntactic category, a logical form representation.There are difficulties in representing CCG without any visualization tools.This paper presents a design framework of OpenCCG workbench and visualization tool which enables linguists to develop CCG based lexicons more easily.Our research is aimed to resolve these gaps by developing a user-friendly tool.OpenCCG Workbench, an open source web-based environment, was developed to enable multiple users to visually create and update grammars for using with the OpenCCG library.It was designed to streamline and speed-up the lexicon building process, and to free the linguists from writing XML files which is both cumbersome and error-prone.The system consists of three sub-systems: grammar management system, grammar validator system, and concordance retrieval system.In this paper we will mainly discuss the most important parts, grammar management and validation systems, which are directly related to a CCG lexicon construction.We support users in three levels; Expert linguists who play a role as lexical entry designer, normal linguists who adds or edits lexicons, and guests who requires an acquisition to the lexicon into their applications.
