8. A computer program product for augmenting a semantic model from unstructured data, the computer program product comprising: a computer readable storage medium having program instructions embodied therewith, wherein the program instructions are executable by a computer processor to cause the computer processor to perform a method comprising: determining a root of a first element selected from a domain of a semantic model, wherein the domain includes a plurality of elements that lack relationship information between the plurality of elements; generating 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, wherein a selection of the preposition that is added to the root of the first element depends upon whether the root is determined as a noun or a verb, as the root occurs in the first element of the domain of the semantic model; performing a search of one or more unstructured data sources, based on the search token that is generated; determining whether results of the search, at least one phrase that contains an approximate match to the search token; in response to determining the results of the search include at least one phrase that contains an approximate match to the search token, generating a triple from the at least one phrase, and adding the triple to the semantic model; and adding a predicate of the triple, to a second element of the domain of the semantic model forming a second triple, wherein the predicate of the triple expresses a relationship between the first element of the domain of the semantic model and the second element of the domain of the semantic model.

The computer program product of claim 8 , further comprising: parsing the at least one phrase to form a phrase-structure tree; determining a type of phrase for each portion of the phrase-structure tree, and a part of speech for each word of each portion of the phrase-structure tree; determining a probability of an accurate determination of the type of phrase and part of speech of each portion of the phrase-structure tree; and generating a triple from the phrase-structure tree based on the parsing, the determining of the type of phrase and the part of speech, and the determining of the probability of the accurate determination of the type of phrase and the part of speech, wherein the triple includes a subject, a predicate, and an object.
