Allows approximate mapping between two different ontologies. The mapping is obtained combining sets of matchers that compare different features of elements from the two ontologies.
An introduction to the framework can be found in:
Using Dempster-Shafer for Combining Ontology and Schema Matchers

Limitations
There are some limitations in the structure of the ontologies it can parse.
At the moment, it finds entities (classes, instances and properties) if they are identified at least once using the attribute rdf:ID
Entities that are only referred using rdf:about are not extracted by the parser.
