CORDULA: Software Requirements Extraction Utilizing Chatbot as Communication Interface

Natural language requirement descriptions are often unstructured, contradictory and incomplete and are therefore challenging for automatic processing. Although many of these deficits can be compensated by means of natural language processing, there still remain cases where interaction with end-users is necessary for clarification. In this vision paper, we present CORDULA, a system using chatbot technology to establish end-user communication in order to support the requirement elicitation and partial compensation of deficits in user requirements.
