The underlying data can be structured or unstructured in nature. For unstructured data, more particularly, the present invention allows users to state questions or problems in plain language (English or other), audio, images, video, sensor data, or other information format. The present invention then analyzes the information and performs semantic information extraction to translate the human-stated questions (or problem queries) into Resource Description Framework (RDF) data model ontological subject-predicate-object expressions (triples, in RDF terminology). The question (or problem) statement defined in RDF format, is based on the Ontology-based Search Engine compatible parameters, which allows specific answers (or solutions) to be identified. Extracted questions/problems and answers/solutions are integrated back into the data model.

The invention provides, in one aspect, a method for visualizing relationships among triples of an RDF data set. The method, which can be used with a data set already in RDF form or converted thereto (e.g., from relational, hierarchical or other form), includes the steps of grouping subjects of at least selected ones of the triples based on commonality of at least portions of the identifiers of those subjects. It further includes grouping, for at least a selected subject groups, objects based on commonality of at least portions of identifiers of the predicates of those triples. Icons representing the subject and object groups can be displayed, e.g., on a computer monitor, or otherwise. A related aspect of the invention provides the additional step of displaying icons, e.g., directed arrows, indicating relationships among icons that represent subject group and icons that represent object groups. A display so generated is reminiscent of a directed graph—albeit a novel such graph that represents relationships among groups of subjects and objects, rather than directly between individual subjects and objects.
