Abstract
Method to calculate time weight in an RDF graph, including: providing one or more triples of the RDF graph to an inference engine module, the one or more triples comprising a time information; providing a reference time to the inference engine; calculating an elapsed time from the reference time to the time value; and inversely weighting the time information by the elapsed time to provide a calculated time weight. Another embodiment may provide a method to update a time weight of a relation when an RDF graph has been added to or deleted from the relation. Another embodiment may provide a method to update a time weight of a relation represented by an RDF graph, when a new reference timestamp is provided. Another embodiment may provide a system to calculate time weight in an RDF graph.
