Abstract
The success and widespread use of Web service technol-
ogy is bound to the availability of tools for rapidly discover-
ing services and for composing their operations. We present
a system for service discovery and composition based on
syntactic and semantic matching of the published service in-
terfaces. The system relies on accurate preprocessing of the
available services, that is, on the indexing time of the ser-
vices' descriptions. The composition task is performed by
index lookup and an efficient heuristic for graph traversing.
The presented system is the VitaLab entry for the Syntactic
and Semantic WS-Challenge 2006.
1. Introduction
One of the most intriguing visions brought by the Web
service technologies is that of dynamic discovery from a
large set of services and invoking their operations to achieve
