BUPTTeam at the NTCIR-13 STC-2 Task

This paper provides an overview of BUPTTeam’s system participated in the Short Text Conversation (STC) task of Chinese at NTICR-13. STC is a new NTCIR challenging task which is defined as an information retrieval (IR) or natural language generation problem. In this paper, we propose a novel method to generate appropriate comments based on the following four steps: 1) preprocessing, 2) model building, 3) candidate comments generation, 4) candidate comments ranking. The evaluation results show that our methods finish the task successfully and have positive effect on improving the evaluation measurement.
