Obtaining candidates for a relationship type and its label

Abstract:

The present invention may be a method, a computer system, and/or a computer program product. An embodiment of the present invention provides a computer-implemented method for obtaining one or more candidates for a relationship type and its label. The method comprises the following steps: analyzing a document annotated with entity types, the analysis comprising counting the number of pairs of co-occurring entity types in each sentence in the document, and judging whether there exists, in the document, a candidate for a label of a relationship type which shows relationship between or among the co-occurring entity types and, if the judgment is positive, storing a candidate for the relationship type and a candidate for its label; and outputting a result of the analysis. The method may further comprise, if the judgment is negative, storing a candidate for the relationship type without a candidate for its label.
