Abstract. This paper is on the automation of knowledge-intensive tasks in engineering domains; here, the term “task” relates to analysis and synthesis tasks, such as diagnosis ...
In this paper, we propose to deploy type-theoretic techniques to the service description and composition verification. We define a flexible type system for modeling instances a...
