Huge amounts of information in digital format are currently available; for example, the world-wide-web is an immense source of text, images, video, and sound. Structuring/understanding this vast amount of multimedia information is a difficult task. Accessibility issues arise in this context, with personal identification techniques playing a key role in designing human-machine interfaces for security reasons and and accessing restricted-access systems. Pattern recognition (PR) and machine learning (ML) techniques provide formal frameworks in which this class of problems can be adequately addressed. On the other hand, exploratory analysis (data mining) and content-based retrieval of multimedia data serve both as important practical application domains for PR and ML techniques and as a source of challenging research problems. The aim of this workshop is to bring together researchers, practitioners and potential users with interests in the multidisciplinary topics listed above. This
volume contains all the papers presented at PRIS 2005, held in Miami, Florida, USA, May 24-25, 2005. A total of 26 papers were selected from 39 submitted papers. Of these, 17 were selected for oral presentation arranged in a single track program and 9 where selected for a poster session. In addition, we invited two distinguished researchers, José Carlos Príncipe from the University of Florida, USA and Jake Aggarwal from the University of Texas, USA, to give keynote addresses. We would like to express our sincere gratitude to all the members of the program committee for doing an excellent job in reviewing the papers which has resulted in ensuring a high quality proceedings. Special thanks go to the invited speakers for their valuable contributions. We would also like to acknowledge all the authors for submitting papers, and all the participants who made this meeting successful. PRIS 2005 has been sponsored by the International Association of Pattern Recognition (IAPR). The workshop was organized under the umbrella of the ICEIS 2005 - International Conference on Enterprise Information Systems. Our thanks go to ICEIS 2005 for providing us the local organization support and facilities. Special thanks are due to Vitor Pedrosa for secretarial. We appreciate the help of the editorial staff of INSTICC PRESS, in particular Bruno Encarnação, who supported the publication of these proceedings.
