Introduction:Intelligence and Security Informatics (ISI) is concerned with the study of the development and use of advanced information technologies and systems for national, international, and societal security-related applications. The annual IEEE International Conference series on ISI was started in 2003. In 2006, the Workshop on ISI was started in Singapore in conjunction with PAKDD, with most contributors and participants from the Pacific Asian region. Since then, PAISI was held annually in Chengdu (2007), Taipei (2008), Bangkok (2009), Hyderabad (2010), Beijing (2011), and Kuala Lumpur (2012). This year, PAISI 2013 will be held in conjunction with IJCAI (http://ijcai-13.org) and will provide a stimulating forum for ISI researchers in Pacific Asia and other regions of the world to exchange ideas and report research progress.
All papers accepted by PAISI 2013 will be published in Springer's LNCS (Lecture Notes in Computer Science) series.
