Abstract

An apparatus and a hybrid method for recognizing answer type are disclosed. The apparatus includes: a morpheme analyzer for analyzing morphemes of an input text; a syllabic answer type recognizer for extracting a predetermined size syllable from a morpheme list and recognizing an answer type based on the extracted syllable; a vocabulary feature recognizer for allocating feature to each morpheme and recognizing the feature; a vocabulary feature disambiguation unit for disambiguating vocabulary feature ambiguity of morphemes having more than one feature; a pattern rule answer type recognizer for recognizing an answer type by comparing a consecutive sequence of the morphemes and a consecutive sequence of constitutional features connected to the morphemes with a pre-constructed pattern rules; a statistic answer type recognizer for recognizing an answer type by implementing a statistic model; and an answer type sub-category recognizer for recognizing a sub-category of the recognized answer type classified to general category.

Claims21

Dependent claims

A hybrid apparatus for recognizing answer type, the apparatus comprising:

a morpheme analyzer for analyzing morphemes of an input text;
a syllabic answer type recognizer for extracting a predetermined size of syllable from a morpheme list analyzed by the morpheme analyzer and recognizing an answer type based on the extracted syllable;
a vocabulary feature recognizer for allocating corresponding feature to each of morphemes constructing the morpheme list and recognizing the corresponding feature of each morpheme;
a vocabulary feature disambiguation unit for disambiguating vocabulary feature ambiguity of morphemes having more than one feature recognized at the vocabulary feature recognizer;
a pattern rule based answer type recognizer for recognizing an answer type by comparing a consecutive sequence of the morphemes and a consecutive sequence of constitutional features connected to the morphemes with a pre-constructed pattern rules;
a statistic answer type recognizer for recognizing an answer type by implementing a statistic model to the consecutive sequence of the morphemes and the consecutive sequence of constitutional features connected to the morphemes;
and
an answer type sub-category recognizer for recognizing a sub-category of the recognized answer type classified to general category at the statistic answer type recognizer.
