The Lotus Knowledge Discovery System from IBM uses several leading-edge technologies to systematically create associations between corporate expertise and information resources, personalize and organize knowledge for individuals and communities, and provide a place for teams to work, make decisions, and act. It also creates a searchable index, computes document values, and provides a search-and-browse user interface. This paper describes the technology behind the knowledge management components of the product and describes the experience of the United States Joint Forces Command, one of the product's earliest adopters. The Joint Forces Command combined a new knowledge management methodology with the software tools, and the Lotus team gained valuable deployment experience in the process.
