1. A computer-implemented method of active learning domain-specific ontologies based on unsupervised learning of ontologies from corpora of natural-language text documents and expert guidance to update the ontologies, the method comprising:
obtaining, with a computer system, a set of ontologies, wherein ontologies in the set of ontologies map n-grams onto concepts to which the n-grams refer in different respective domains of knowledge;
receiving, with the computer system, an update associating a first n-gram with a first concept;
receiving, with the computer system, information by which the update is associated with a given domain of knowledge of a user providing the update;
selecting, with the computer system, a subset of ontologies from among the set of ontologies by determining that the update in the given domain of knowledge is applicable to respective domains of knowledge of the subset of ontologies;
determining, with the computer system, that the first concept has a specified type of relationship to a subset of concepts to which other n-grams are mapped in the subset of ontologies; and
storing, in memory of the computer system, in response to the determination, associations between the first n-gram and the subset of concepts in at least some of the subset of ontologies.
