This volume contains papers selected for presentation at the Seventh International Symposium on Methodologies for Intelligent Systems (ISMIS '93), held at the Norwegian Institute of Technology, Trondheim, Norway, in June 1993. The volume includes six invited talks and 43 contributed papers organized under the following headings: logic for artificial intelligence, expert systems, intelligent databases, approximate reasoning, constraint programming, learning and adaptive systems, methodologies, knowledge representation, and manufacturing. Theinvited talks are: "On extended disjunctive logic programs" (J. Minker, C. Ruiz), "Towards intelligent databases" (F. Bry), "Methodologies for knowledge-based software engineering" (M. Lowry), "Modelling of industrial systems" (L. Ljung), "The many faces of inductive logic programming" (L. De Raedt, N. Lavrac), and "Systematic assessment of temporal reasoning methods for use in autonomous agents" (E. Sandewall).
