Title:
形態素解析装置及び形態素解析プログラム
Document Type and Number:
Japanese Patent JP3986531
Kind Code:
B2
Abstract:
The morphological analysis apparatus according to the present invention, comprises a spelling recovery unit that recovers the spellings of words, a morphological analysis candidate generation unit that segments a word sequence composed of words, the spellings of which have been recovered, into morphemes, appends POS tags to the morphemes and generates a single morphological analysis candidate or a plurality of morphological analysis candidates, a generation probability calculation unit that calculates a generation probability for each morphological analysis candidate having been generated based upon the product of the probability of the pre-spelling recovery word being converted to the post-spelling recovery word and the probability of a morpheme sequence and a POS sequence being generated from the post-spelling recovery word sequence and a solution search unit that selects through a search the most likely candidate as a solution from all the morphological analysis candidates for which the generation probabilities have been calculated by the generation probability calculation unit.
