This volume contains the texts of papers presented at the Second Irish Conference on Artificial Intelligence and Cognitive Science, held at Dublin City University in September 1989. This Conference has now become the major annual forum in Ireland for the presentation and discussion of current research work in the multi-disciplinary area of Artificial Intelligence. Papers in this volume have been divided into seven sections which vary in their subject matter. Image processing, human-computer interaction, planning, applications and theory of expert systems, learn ing, speech, and natural language processing and semantics repre sents as broad a spectrum of AI and AI-related topics as can be found in current AI research. This harmonises quite well with the aims and scope of the AICS'89 conference which were to provide a forum for industry and academic research to discuss AI and AI-related topics and we were delighted that such a broad coverage of topics was achieved. Despite the broad nature, however, none of the papers are primarily review articles; each paper presents new research results within its own specific area.

th Welcome to the 15 International Multimedia Modeling Conference (MMM 2009), held January 7–9, 2009 at EURECOM, Sophia-Antipolis, France. MMM is a leadinginternationalconference for researchersandindustry practitionersto share their new ideas, original research results and practical development ex- riences from all multimedia-related areas. MMM 2009 was held in co-operation with the ACM Special Interest Group on MultiMedia (ACM SIGMM). It was a great honor to host MMM 2009, one of the most long-standing th multimedia conferences, at EURECOM in Sophia-Antipolis, France. The 15 edition of MMM marked the return of the conference to Europe after numerous years of activity in Asia, and we are proud to have organized such a prestigious conference on the French Riviera. EURECOM is an engineering school in the domain of information and communication technology and a research center in communication systems. Since its creation in 1991 by TELECOM ParisTech and EPFL, it has developed strong international links with both academic and industrial partners. The heart of EURECOM is its internationally renowned research activities which focus on three areas: networking and security, mobile communications, and multimedia.

LifeLogging: Personal Big Data provides a comprehensive summary of lifelogging, to cover its research history, current technologies, and applications. It is a suitable reference for those seeking an information retrieval scientist's perspective on lifelogging and the quantified self.

Abstract: "The notion of searching a hypertext corpus has been around for some time, and is an especially important topic given the growth of the World Wide Web and the general dissatisfaction users have with the tools currently available for finding information on the Web. In response to this, a workshop was held as part of SIGIR'98 on Hypertext Information Retrieval for the Web and this document presents a brief summary of the papers presented at that workshop, along with a set of themes identified as a result of group discussion and some conclusions on where to go next."
