Abstract: A computer-implemented display of semantically characterized information can include cohort indicators representing a group of one or more specified cohort parameters applied in such a way so as to filter a dataset comprising RDF structured data items. Each cohort indicator can be associated with a set of RDF structured semantic predicates. At least one selectable facet value indicator can be included that represents one or more specified value parameters each being associated with a RDF structured semantic object. The one or more specified value parameters can be applicable to the dataset in such a way so as to enable additional filtering and modification of one or more of the resulting cohort groups of information. A visual display of filtered information can be included which results from separately applying, against the dataset, each group of one or more specified cohort parameters represented by each cohort indicator.
