Abstract
Methods are disclosed for acquiring ontological knowledge using query logs. In one embodiment, query logs are first utilized as a basis for identifying important contexts associated with terms belonging to a semantic category. Then, those contexts are as a basis for identifying new terms belonging to the same category or, in another embodiment, as a basis for removing extraneous or obsolete terms identified as being in the same category.
Claims20
A computer-implemented method for acquiring ontological knowledge, the method comprising:
- obtaining a seed term that is classified within a semantic category;
- and
- identifying, from a query log, a context associated with the seed term.
A computer-implemented method for acquiring ontological knowledge, the method comprising identifying, from a query within a query log, a new term for classification within a semantic category.
A computer-implemented method for acquiring ontological knowledge, the method comprising:
- receiving an indication of a category and a seed term;
- identifying at least one instance of the seed word within a query log;
- and
- utilizing said at least one instance as a basis for identifying a term that occurs within the query log and is consistent with the category.
