Over the years, researchers have investigated how to provide better support for hospital administration, therapy and laboratory workflows. Among these efforts, as with any other safety critical system, reliability of the workflows is a key issue. In this paper, we provide a method to enhance the reliability of real world workflows by incorporating timed compensable tasks into the workflows, and by...
Workflows have proven to be a useful conceptualization for the automation of business processes. While formal verification methods (e.g., model checking) can help ensure the reliability of workflow systems, the industrial uptake of such methods has been slow largely due to the effort involved in modeling and the memory required to verify complex systems. Incorporation of time constraints in such systems...
Community-based question answering services accumulate large volumes of knowledge through the voluntary services of people across the globe. Stack Overflow is an example of such a service that targets developers and software engineers. In general, questions in Stack Overflow are answered in a very short time. However, we found that the number of unanswered questions has increased significantly in...
Automated Theorem Proving systems are enormously powerful computer programs capable of solving immensely difficult problems. The extreme capabilities of these systems lie on some well-established proof systems. Semantic tableau is such a proof system used to prove the validity of a formula by contradiction and can produce a counterexample if it fails. It can also be used to prove whether a formula...
