The conference on Natural Language Processing and Chinese Computing (NLPCC) is the annual conference of CCF TCCI (Technical Committee of Chinese Information, China Computer Federation). The first and the second NLPCC conferences were successfully held in Beijing in 2012 and Chongqing in 2013. As a leading conference in the field of NLP and Chinese Computing, NLPCC has been the premier forum for Chinese researchers and practitioners in NLP from academia, industry, and government to share their ideas, research results and experiences, and to promote the research and technical innovations in these fields. From this year, NLPCC will become an international conference. Contributions from not only China, but also Pacific Asia areas and all over the world are solicited. Natural language processing and Chinese information technologies are among the most active research and development areas due to the innovations and applications on Internet as well as the rapid development of mobile devices in the last decade. The areas are facing new challenges arisen from intelligent applications and big data. This third edition of NLPCC will focus on Deep Understanding of Natural Language Data and Better Integration with Knowledge, by exploring various techniques and resources including Web Mining & Big Data, Multi-Lingual Access, Machine Learning for NLP, Knowledge Acquisition in Social Networks, Search & Ads, Question Answering as well as the Fundamentals and Applications on Language Computing. The conference welcomes different types of contributions describing new concepts, innovative research work, standards, implementations and experiments, applications, and industrial case studies. Authors are invited to submit complete and unpublished papers, which are not under review in any other conference or journal. The conference language is English. However, to promote Chinese computing, submissions in Chinese in this area will also be considered.
