Mahdi Sargolzaei will present a paper at the 11th International Conference on Software Engineering and Formal Methods (SEFM 2013) which is held in in Madrid, Spain on September 25-27, 2013. Its title is “A Tool for Behaviour-based Discovery of Approximately Matching Web Services” and you can find the abstract below.

We present a tool that is able to discover stateful Web Services in
a database, and to rank the results according to a similarity
score expressing the affinities between each of them and a user-submitted
query. To determine these affinities, we take behaviour into account, both
of the query and of the services. We define the states a service can switch
into, as well as the state- and data-dependent conditions that trigger such
transitions. Therefore, a user may specify the desired sequence of actions
for a target service. The names of service operations, their order of invocation,
and their parameters may differ from those required by the actual
user, e.g. “getWeather” instead of “g weather”, etc., which necessitates
using similarity scores, and hence the notion of soft constraints. The final
tool is based on Soft Constraint Automata.
