Abstract 

Workflow composition is a crucial part of day-to-day automation, where many different parameters and facts need to be taken into account. In order to reach a given goal, a planner calculates the sequence of actions that need to be taken in the current context. Semantic technologies such as RDF annotation and reasoning can help improve this process by enabling more generic implementations, connect to more knowledge, an introduce more flexibility. However, it is currently difficult to express change in first order logic, semantic reasoning, and the proofs they produce. What if a change in the context invalidates the current plan?

In this talk, I will introduce smart workflow composition method based on Weighted Transition Logic and implemented in Notation3 logic—a superset of RDF. Actions are described as changes to the RDF state, resulting in a more adaptive and change aware workflow composition process. After a basic introduction of the general concepts, I will discuss several applications in the healthcare, public services or transport domain.
