Abstract

Finding the “right information is an ever increasing problem. The amount of digital content is growing at a staggering rate. Yet, at the same time, workers expectations regarding what information is available and how fast it should be delivered are also ever increasing. This work presents a case study that explores an architecture suited to a distributed corporate intranet. The architecture leverages knowledge of domain content to assist in metadata harvesting. The technologies realized in the instantiated architecture are then used to reproduce a tool to aid knowledge workers in information gathering and discovery. The architectural framework was proposed by NASA’s Jet Propulsion Lab (JPL) and advocates the deployment of a service-oriented architecture (SOA) to assist in meeting the on-time, on-task search needs of NASA scientists and engineers. The lessons learned and technologies used in instantiating the architecture are captured to benefit researchers and practitioners.
