Conformance Analysis of Execution Traces with Clinical Guidelines and Basic Medical Knowledge in Answer Set Programming ⋆

Abstract. Clinical Guidelines (CGs) are developed for specifying the “best ” clinical procedures for specific clinical circumstances. However, a CG is executed on a specific patient, with her peculiarities, and in a specific context, with its limitations and constraints. Physicians have to use Basic Medical Knowledge (BMK) in order to adapt the general CG to each specific case, even if the interplay between CGs and the BMK can be very complex. In this paper, we focus on a posteriori analysis of conformance, intended as the adherence of an observed CG execution trace to CG and BMK knowledge. A CG description in the GLARE language is mapped to Answer Set Programming (ASP); the BMK and conformance rules are also represented in ASP, to perform conformance analysis, identifying non-adherence situations to CG and/or BMK, which must ultimately be evaluated by a physician in order to assess whether a trace can be considered as conformant or not.

Business process verification with constraint temporal answer set programming

The paper provides a framework for the verification of business processes, based on an extension of answer set programming (ASP) with temporal logic and constraints. The framework allows to capture expressive fluent annotations as well as data awareness in a uniform way. It allows for a declarative specification of a business process but also for encoding processes specified in conventional workflow languages. Verification of temporal properties of a business process, including verification of compliance to business rules, is performed by bounded model checking techniques in Answer Set Programming, extended with constraint solving for dealing with conditions on numeric data
