During the period 1996-2002 I did not lead a group of graduate students directly, due to a number of other activities during various parts of that period, including, in particular:
EMTEK was a small project for implementation work in the general area of software support for publication and communication activities in research. It was not a research group and was never intended to be one. Besides software support for the newly-founded Linköping University Electronic Press, the project developed an experimental web-based support for integrated document handling in a research environment. Some parts of the resulting system can still be seen at the EMTEK website which also contains descriptions of the group itself. This system addressed the same issues as the LOIS system that was done in the ASLAB-OIS group.
Also during this period, Choong-ho Yi pursued his Ph.D. studies on the topic of business process modelling using an explicit-temporal logic in the Features and Fluents tradition (see Hyperbook > Knowledge Representation > Explicit-Temporal Logic for details). He had done his licentiate degree in RKLLAB and continued to the Ph.D. while working at Karlstad Universityand at the Research Institute of National Defense. His thesis, "Modelling Object-Oriented Dynamic Systems Using a Logic-based Framework" was defended in 2002.
From my point of view, at the time when we were developing the workflow concepts in the ASLAB-OIS group (1979-1982) we had seen the need for reasoning about actions in order to characterize flexible and goal-directed workflow, but we did not have the formal means at the time. The development of the Features and Fluents framework gave us the beginnings of adequate tools, and Choong-ho continued the work.
The continuation of the EMTEK activities are presently being conducted as a development group for Electronic Publication Overlay Systems (EPOS) within Linköping E-Press. Details will follow.
