APPARATUS FOR TEXT LEARNING BASED STATISTICAL HMM PART OF SPEECH TAGGING AND METHOD THEREOF

摘要

PURPOSE: A statistical HMM part tagging apparatus and a method thereof for increasing the tagging performance of a morpheme part are provided to increase the accuracy of tagging about a document of a domain by using learning information. CONSTITUTION: A real time learning based statistical part tagging unit(103) utilizes vocabulary stored in a vocabulary probability information DB and context stored in a context probability information DB. A real time learning based tagging error correction unit(105) corrects an error through a tagging error modification DB. A real time document information learning unit(101) establishes real time context probability information DB after extracting context probability information.
