The usability of a lexical database of a natural language on an online platform is in great demand in this new era of online language education. An interface of this kind can primarily serve three different purposes: first, it plays an operational role in new frame of multimodal education system; second, it partly fulfills the necessity of online lexical resources which are in increasing need in research and application in the field of language technology; and third, it becomes a useful and omnipresent resource for native and foreign language users who want to learn meanings and usages of words of a natural language for different personal, academic, philanthropic and commercial purposes. Keeping these applications in view, in this paper, we describe the process that we apply to develop an online platform for the Bengali WordNet, which offers a unique opportunity for multimodal lexical learning to the Bengali learners. The proposed work, that we want to present in this paper, has the potentials to fulfill all the three needs stated above. While the WordNet provides different kinds of information directly associated with words, the digital platform has a very sensitive user-friendly interface for the access of the lexical resources stored in the WordNet.
