Model-based technologies improve the efficiency of the design and development of IT
systems by making it possible to automate verification, code generation and system
analysis based on a formal model. A simple way of describing the behavior of systems
is state-based modeling, which - due to the advancements of formal analysis techniques
in recent years - can be widely and effectively utilized when analyzing systems. A
possible way of synthesizing such models is to apply active automata learning algorithms.
Acquiring a correct formal model of a system can be challenging because of the different
theoretical and practical obstacles of both manual and automated approaches. We propose
a semi-automated solution, that applies automata learning to provide an interactive
environment for model development.
