SWSRAT
Semantic Web Service Relevance Assessment Tool
A PHP based web application to support user assesments of semantic web services given service requests. Uses a MySQL database to store data. Based on service collections like SWASDL-TC 1.1 and OWLS-TC 1.1, the tool provides pairwise comparisons of service requests and service offers, maintains user judgements in different (graded) ranking scales and allows to export these assessments in different variations and with user-based filters as xml file.
SWSRAT has been developed jointly with MSc. Patrick Kapahnke and PD. Dr. Matthias Klusch at the German Research Center for Artificial Intelligence (DFKI) in the Intelligent Information Systems (I2S) research team.
This work has been supported in part by the German ministry for education and research (BMBF) in the project MODEST. It is licenced under the Mozilla Public License version 1.1.
