This book constitutes the refereed proceedings of the second international workshop on Innovative Internet Computing Systems, IICS 2002, held in Kuhlungsborn, Germany in June 2002. The 19 revised full papers presented together with an invited paper were carefully reviewed and selected from over 30 submissions. Among the topics addressed are large-scale distributed computing infrastructures presenting new challenges to information and Web technology, the management and retrieval of web-based information, content classification, web-based communities management, structure and retrieval of information from large distributed data bases, and the representation of the distributed nature of information by means of graph-theoretical models.
