The conference on Natural Language Processing and Chinese Computing (NLPCC) is the annual meeting of the CCF TCCI (Technical Committee of Chinese Information, China Computer Federation). NLPCC is a leading international conference specialized in the fields of Natural Language Processing (NLP) and Chinese Computing (CC). It serves as a main forum for researchers and practitioners from academia, industry, and government to share their ideas, research results and experiences, and to promote their research and technical innovations in the fields. Previous NLPCC conferences were successfully held in Beijing (2012), Chongqing (2013), Shenzhen (2014), Nanchang (2015), Kunming (2016) , and Dalian(2017).Today, NLP and CC technologies are among the most active research and development areas due to rapid advancement of the Internet as well as the worldwide proliferation of mobile devices and social media. The fields are facing many new challenges arising from intelligent applications and big data, such as business intelligence, social analytics, etc. The Seventh Conference of NLPCC will focus on Natural Language Analysis and Understanding in Big Data and Artificial Intelligence including Fundamental Research in Language Computing, Multilingual Access, Web Mining/Text Mining, Machine Learning for NLP, Knowledge Graph, Information Extraction, Question Answering, Information Retrieval, Chatbot, NLP for Social Networks, as well as the Applications of Language Computing.NLPCC 2018 welcomes original technical papers on new concepts, innovative research, systems, standards, testing & evaluation, applications, and industrial case studies related to NLP & CC. Authors are invited to submit complete and unpublished papers in English or in Chinese.
