Fig. 6. The S³C Solution Explorer Application
The EDDiE Service Discovery Engine uses the information gathered with the S 3 C
Solution Explorer as input to retrieve services. EDDiE implements advanced term
disambiguation and query expansion algorithms to add different terms with similar
meanings to the query using the WordNet online lexicon [15, 16], thus increasing the
number of web services retrieved from the registries. Furthermore, EDDiE provides
capabilities to calculate the relevance of a discovered service [14].
The SeCSE Management Service provides an application interface to the SeCSE
Registry via a web service. It is used to manage providers, services and meta-data
such as description, quality of service, commercial information and signatures.
The SeCSE Service Registry is a XML database that holds all the information about
services and their descriptions. While SeCSE tools used a federated online database,
the S 3 C solution is based on a locally installed database.
4 Initial Evaluation of the S 3 C Solution Explorer
Our evaluation strategy focused on investigating the utility of the S 3 C Tool Environ-
ment. We conducted two studies at different ERP partners who both follow Sure Step.
We first performed an initial utility and usability study at Terna to figure out whether
the S 3 C Solution Explorer application fulfills the key requirements of consultants. The
second evaluation was conducted at InsideAx 2 to investigate the utility of the S 3 C
Solution Explorer in more detail. This study focused on comparing the time needed to
identify relevant services with the help of the S 3 C Solution Explorer to Sure Step and
investigated the correctness and completeness of the solution.
