METHOD FOR TAGGING MORPHOLOGY BY USING PROSODY MODELING AND ITS APPARATUS

摘要

PURPOSE: A morphological part-of-speech tagging method and a device thereof are provided to find suitable morphological part-of-speech about a prosody model of an input voice and tag morpheme part of speech based on result, thereby maximizing accuracy of morpheme part of speech tagging. CONSTITUTION: A morpheme analysis unit(203) analyzes morpheme about a text sentence based on morphological part-of-speech sequence prosody model. If ambiguity exists in the morpheme analysis result, a prosody model detector(207) detects prosody model about voice. A prosody model comparing/determining unit(209) compares a prosody model about the voice with the morphological part-of-speech sequence prosody model and determines morpheme part of speech sequence of a prosody model about the voice. A part-of-speech tagger(211) adds up part-of-speech sequence information of a prosody model about the voice in the morpheme part of speech sequence result and tags a part of speech.
