The truth is in here
Knowlus is the Web 2.0 service (also SaaS and PaaS) for intelligent modules such as expert system shells, decision support systems, CSP solvers, neural networks and so on. Experts, decision makers and users are able creating content (knowledge bases, preference profiles, etc.) using these modules and solving their own problems in various application domains. Multiple modules, e. g., several expert system shells, allows efficient problem solving both in terms of computational efficiency and minimization of expert’s cognitive efforts.
