COMPASS
   Goal: consolidate, integrate theoretical basis of algebraic specification methods and apply it to software. The algebraic approach supports precise specification of semantics of generic reusable system components, providing formal conceptual basis for ste

ResearchIndex: Proof Theoretic Approach To Specification Languages
   Thesis studies FORUM as specification language. FORUM is a higher order logic based on the logical connectives of Linear Logic. Initial example demonstrates that FORUM is well suited to specify concurrent computations by specifying the higher order ß cal

ResearchIndex: Structure-preserving specification languages for knowledge-based systems
   Much work on validation and verification of knowledge based systems (KBSs) has been done in implementation languages, mostly rule based. Recent papers suggest it is useful to do validation and verification in a more abstract and formal specification of th
