Web-Age Information Management : WAIM 2014 International Workshops: BigEM, HardBD, DaNoS, HRSUNE, BIDASYS, Macau, China, June 16-18, 2014, Revised Selected Papers

WAIM is a leading international conference on research, development, and appli- tions of Web technologies, database systems, and information management. Tra- tionally, WAIM has drawn the strongest participation from the Asia-Pacific region. The previous WAIM conferences were held in Shanghai (2000), Xi'an (2001), Beijing (2002), Chengdu (2003), Dalian (2004), Hangzhou (2005), Hong Kong (2006), Huangshan (2007), Zhangjiajie (2008), and Suzhou (2009). In 2010, WAIM was held in Jiuzhaigou, Sichuan, China. This high-quality program would not have been possible without the authors who chose WAIM for disseminating their contributions. Out of 205 submissions from 16 countries and regions, including Australia, Canada, France, Germany, Hong Kong, Japan, Korea, Macau, Malaysia, Mainland China, Saudi Arabia, Singapore, Taiwan, Thailand, UK, and USA, we selected 58 full papers and 11 short papers for publi- tion. The acceptance rate for regular full papers was 28%. The contributed papers addressed a wide range of topics such as Web, XML, and multimedia data, data pr- essing in the cloud or on new hardware, data mining and knowledge discovery, inf- mation integration and extraction, networked data and social networks, graph and stream processing, similarity search, etc. We are also grateful to our distinguished keynote speakers Prof. Jianzhong Li, Dr. Divesh Srivastava, Prof. Katsumi Tanaka, and Prof. Xiaofang Zhou. A conference like WAIM can only succeed as a team effort. We want to thank the Program Committee members and the reviewers for their invaluable efforts.
