摘要：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 themorphemes and generates a single morphological analysis candidate or a plurality ofmorphological analysis candidates, a generation probability calculation unit thatcalculates a generation probability for each morphological analysis candidate havingbeen generated based upon the product of the probability of the pre-spelling recoveryword being converted to the post-spelling recovery word and the probability of amorpheme sequence and a POS sequence being generated from the post-spellingrecovery word sequence and a solution search unit that selects through a search themost likely candidate as a solution from all the morphological analysis candidates forwhich the generation probabilities have been calculated by the generation probabilitycalculation unit.
