AUGMENTING SEMANTIC MODELS BASED ON MORPHOLOGICAL RULES

A computer processor determines a root of a first element of a semantic model, in which a first relationship of the first element to a second element of the semantic model, is unknown. The computer processor generates a search token, based on applying morphological rules to the root of the first element and appending a preposition. The computer processor determines one or more regular expressions by applying the search token to search a source of unstructured data. The one or more regular expressions are in a form of a triple, having a subject, a predicate, and an object, and the computer processor applies the predicate of the triple as the first relationship of the first element of the semantic model to a second element of the semantic model.
