METHOD FOR ANALYZING MORPHEME OF KOREAN LANGUAGE BY USING DICTIONARY STRUCTURE

摘要

PURPOSE: A Korean morpheme analysis method is provided to analyze morphemes of the Korean by using a structure of a dictionary(AVL, Adelson-Velskii and Landis + Trie, reTrieval) for reducing a load of a word cluster engine with an input list generator of a word clustering engine. CONSTITUTION: The method comprises steps of extracting words from a sentence by separating words based on a space, a comma or other special characters(100), checking if each separated word is included in a compressed stop word dictionary formed of words having a high appearance frequency among no noun words, i.e. verbs, adjectives or adverbs by the full matching algorithm(103), if the word is not included in the compressed stop word dictionary, checking if the word is included in a noun dictionary by the longest matching algorithm(104), if the word is included in the compressed stop word dictionary, checking the next word(102), if the word is not included in the noun dictionary, determining if there occurs an inappropriate error at the words remaining after extracting the words included in the noun dictionary by referring to a general noun dictionary and a dependency morpheme dictionary(105), if there occurs an inappropriate error, registering the corresponding word at a non-registered word process module, extracting the nouns included in the noun dictionary(106), checking if there exists a list of adjacent nouns(107), designating the adjacent nouns as a noun phrase and checking if the noun phrase is available(108), and transmitting the extracted nouns or noun phrases to an application database(109).
