Model checking algorithms can report a property as being true for reasons that may be considered vacuous. Current algorithms for detecting vacuity require either checking a quadrat...
Formal analysis can be used to verify that a model of the system adheres to its requirements. As such, traditional formal analysis focuses on whether known (desired) system propert...
This paper describes user modelling in I-Help, a system to facilitate communication amongst learners. There are two I-Help components: Private and Public Discussions. In the Privat...

Formalization is a necessary precondition for the specification of precise and unambiguous use case models, which serve as reference points for the design and implementation of so...
In this paper we develop a new elementary algorithm for model-checking infinite sequential processes, including context-free processes, pushdown processes, and regular graphs, tha...
