The SEALS Yardsticks For Ontology Management is an evaluation campaign that comprises a set of evaluations defined with the goal of evaluating the ontology management capabilities of semantic technologies in terms of their ontology language conformance, interoperability and scalability. The main tools targeted are ontology engineering tools and ontology management frameworks and APIs. This year our evaluations will cover the evaluation of conformance, interoperability and scalability with different test data. If you want to see how your tool performs and to compare it with others, join us!
