1. A method for augmenting a semantic model from unstructured data, the method comprising: determining, by a computer processor, a root of a first element of a semantic model; generating, by the computer processor, a search token, based at least in part on morphological rules applied to the root of the first element and a preposition added to the root of the first element; determining, by the computer processor, at least one phrase that substantially matches the search token, by applying the search token to unstructured data; and adding, by the computer processor, a predicate of the at least one phrase, to a second element of the semantic model, wherein the predicate expresses a relationship between the first element of the semantic model and the second element of the semantic model.
