Abstract: We present a rapid question-answering scheme (RQAS) for constructing a chatbot over specific domains with data in the format of question-answer pairs (QAPs). We want RQAS to return the most appropriate answer to a user question in realtime. RQAS is based on TF-IDF scores and exponential elevations of keyword rankings generated by TextRank to overcome the common problems of selecting an answer based on the highest similarity of the user question and questions in the existing QAPs, making it easy for general QAS builders to construct a QAS for a given application. Experiments show that RQAS is both effective and efficient regardless the size of the underlying QAP dataset.
