Current trends require the use of a global information environment, including end-users and loosely coupled knowledge sources (experts, knowledge bases, repositories, etc.) for decision making. This leads to an expansion in e-applications dealing with knowledge storing in the Internet and based on the intensive use of WWW-technologies and standards such as XML, RDF, DAML, etc. A vast diversity of knowledge management tools has made the problem of knowledge fusion (KF) from distributed sources crucial. The above necessitates the development of a KF approach to complex operations management (global understanding of ongoing processes, global knowledge exchange, etc.). The presentation discusses a Knowledge Source Network (KSNet) configuration approach to KF and its potential e-applications for a scalable information environment (infosphere). This approach is based on utilizing such technologies as ontology management, intelligent agents, constraint satisfaction, etc.
