Abstract
At least one term is extracted [202] from unstructured information. The at least one term is validated [204]. Then, a sense of the at least one extracted and validated term is determined [206]. The at least one extracted and validated term is clustered [208] into at least one group of terms according to the determined sense. A taxonomy is generated [210] based on the clustering and a mining of accessible taxonomies.
Claims15
A method [200A] for generating a taxonomy from unstructured information, said method comprising:
- extracting [202] at least one term from unstructured information [122];
- validating [204] said at least one term [124];
- determining [206] a sense of at least one extracted and validated term [108];
- clustering [208] said at least one extracted and validated term [108] into at least one group [112] of terms according to said determined sense;
- and
- generating [210] a taxonomy [120] based on said clustering and a minin of accessible taxonomies.
A system [100] comprising:
- a term extractor [104] configured for extracting at least one term [124] from unstructured information [122];
- a term validater [106] configured for validating said at least one term [124];
- a sense determiner [126] configured for determining a sense of at least one extracted and validated term [108];
- a term clusterer [110] configured for clustering said at least one extracted and validated term [108] into at least one group [112] of terms according to a determined sense;
- and
- a taxonomy generator [118] configured for generating a taxonomy [120] based on said clustering and a mining of taxonomies [102].
A non-transitory computer-readable storage medium comprising instructions stored thereon which, when executed by a computer system, cause said computer system to perform a method [200B] for generating a taxonomy from unstructured information [122], said method comprising:
- extracting [214] at least one term [124] from unstructured information [122];
- validating [216] said at least one term [124];
- determining [218] a sense of at least one extracted and validated term [108], said determining comprising:
- determining a shared sense of a first set of said at least one extracted and validated term [108] that is unambiguous;
- and
- based on a determined shared sense, disambiguating a second set of said at least one extracted and validated term [108] that is ambiguous;
- clustering [220] said at least one extracted and validated term [108] into at least one group of terms according to said determined sense;
- and
- generating [222] a taxonomy [120] based on said clustering and a mining of taxonomies.
