    The authors propose LASSP, an apprentice system for learning problem-solving rules in domains where solving a problem entails multiple, possibly dependent, queries performed on an underlying database. Contrary to other learning apprentice systems, LASSP has a domain theory that is initially empty, yet ever improves in terms of its strength and correctness as successive problem-solving episodes are...

    Although user-friendly and rule-based expert system shells ease the implementation of expert systems and allow for quick prototyping, their use could easily lead to ill-structured knowledge-bases. They provide no methodical way to design and maintain rule-bases (RBs). Thus, the use of these shells does not reduce the complexity of the RB design/maintenance methodology is given. The focus is on the... View full abstract»
