The 2004 IEEE International conference on Information Reuse and Integration (IRI'2004) took place at the Las Vegas Hilton, November 8-10, 2004. This second annual IEEE conference was a very successful event with more than 110 participants. The conference received 168 submissions from 28 countries spread across five continents. Among the submissions, 104 papers were selected for publication and presented during the conference.

The main conference theme was Knowledge Management, but all aspects of information reuse and integration were covered - allowing participants to attend a diversity of presentations. Many prime cross-fertilization scientific exchanges took place! The conference was intellectually challenging as well as entertaining. The scientific highlights included four keynote speeches delivered by very distinguished scientists: Dr. Lawrence O. Hall gave a talk about reusing information by learning models from extreme data sets. Dr. David Fogel from Natural Selection Inc. discussed the role of evolutionary computation in information discovery and reuse in games. A very thought-provoking speech was delivered by Dr. John C. Hansen who argued that computing's maturity is a myth. A fourth keynote speaker was Dr. Phil Calabrese from Data Synthesis who showed how an ordered pairs framework allows one to transcend some limitations of knowledge representation. He also discussed its application to quantum logic. The IRI conference was also very entertaining on the social event side. Attendees will surely not forget the astonishing and funny live-show of a Marilyn Monroe look-alike during the banquet! Also, a Mariachi band brought a typical Mexican and very warm atmosphere during the welcome reception. On all aspects, the venue of the Las Vegas Hilton proved to be a perfect place for both scientific exchanges and entertainment.

Based on the success of the previous year's conference, IRI'2005 will again be held at the Las Vegas Hilton. This year's IRI conference features several tracks on Knowledge Management and the role that information reuse and integration plays here. We have also organized a panel of experts from ONR, NSF, et al. that will discuss the type of projects that are going to be funded now within the context of the conferences theme. It should be emphasized that the IRI conference theme is more general than software - while software is no doubt of fundamental importance, the reuse and integration of knowledge leads to new knowledge and that can be invaluable. This year's venue promises once again to be intellectually challenging as well as entertaining. We invite you to contribute, learn, and partake in the festivities at the Las Vegas Hilton, August 15-17, 2005 - see http://www.cs.fiu.edu/IRI05/.
