The quantities of information available in digital format are exploding in our time. Universities, enterprises and governments have accumulated this information in many diverse multimedia formats, and are asking for systems or models capable of extracting structure or meaning from the data. 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 problem.
The main aim of the International Workshop on Pattern Recognition in Information Systems (PRIS2005) is to bring together researchers, practitioners and potential users with interests in the multidisciplinary field of applications or foundations for Pattern Recognition in Information Systems.
The PRIS workshop series was initiated in 2001 initiated by Ana Fred (Instituto Superior Técnico, Portugal) and Anil K. Jain (Michigan State University USA). After crossing some European countries, this edition was the first on the other side of the Atlantic. The workshop was born in the context of and in conjunction with the International Conference on Enterprise Information Systems (ICEIS).
PRIS 2005 was composed by several sessions of oral presentation and a poster session, summing a total of 22 presentation (14 oral and 8 posters). The oral sessions focused on learning, image recognition, electronic surveillance, and document classification. As in previous editions, PRIS 2005 was sponsored by the prestigious International Association of Pattern Recognition (IAPR).
Two distinguished researchers gave brilliant keynote talks. The opening talk was given by José Carlos Príncipe (USA) on Information Theoretic Learning. On the second day of the workshop, Jake K. Aggarwal addressed the topic of Human Activity Recognition - A Grand Challenge.
A volume with the papers of the PRIS2005 workshop was edited by Hugo Gamboa and Ana Fred in the ICINCO-PRESS.
Next year’s workshop will be presented in conjunction with ICEIS2006 in
22-23 of May 2006
