Abstract

Marl is an ontology designed to use for publishing the results of the opinion mining process in a form of structured data on the Web. The goal is to unify the access the numerical approximation of the opinion concept and allow extensive reasoning and search over multiple resources from different content providers.

Classes

AggregatedOpinionc back to ToC or Class ToC

IRI: http://www.gsi.dit.upm.es/ontologies/marl/ns#AggregatedOpinion

is defined by
http://www.gsi.dit.upm.es/ontologies/marl/ns
The same as Opinion class but indicates that the properties of this class aggregate all the opinions specified in the "extractedFrom" source. Optionally, if the aggregatesOpinion property is used this class could be created to aggregate only certain opinions (e.g. in a text about political scene it there could be many AggregatedOpinion classes each with opinions per different politician).
