State-centric methodology of ontology engineering

While working on ontology engineering for about 25 years, I think I  unconsciously acquired my own methodology of ontology engineering. It is what I call “State-centric” methodology. My background is AI and Engineering rather than logic or philosophy and it must have been driving me to understand the reality in terms of state which is the heart of General Problem Solver (GPS). All my papers on roles, functions, processes/events and causation published in Applied Ontology clearly show the utility of the state-centric methodology. My treatment of context seems rather unique, since I claim any object as a whole provides its parts with a context in which each of them plays the assigned role to make their collection to be a unitary whole. The notion of a non-intentional goal together with the systemic context as its  concretization works very well to capture temporal entities. The success of unified definition of biological and artifact functions is largely based on this idea. Device ontology which I have devised for enabling to capture dynamic and complex phenomena in a consistent manner has been exploited in many of my work on function. It is a role assignment system and fully state-centric. In my recent work on causation, I’ve realized that any causation C->E can be mapped onto a function in which E is a non-intentional goal in the systemic context associated with C->E. The new functional talk of causation is fully state-centric which contrasts with the common idea that state should be excluded from the relata of causation. I found the essence of causation exists in an occurrent in the form of <Event cause State> where State is the resultant state of the Event. In my talk, I will discuss the state-centric methodology through typical achievements on roles, function, processes/events and causation.
