Abstract


The purpose of the study of modern Chinese new words extracted from the text automatically identify and extract new words is also a special case of the word recognition is not logged in Chinese information processing . With the development of society, the new word in large numbers , the identification and extraction of new words more and more attention has been paid . As an important part of the segmentation technology has a key role in the Chinese information processing , the Modern Chinese New Words extraction has important research significance . , Linguists, many of the results of the study of modern Chinese new words are not directly on the computer , only limited word formation rules can be applied to the identification of new words to them . While trying to use the word probability statistics - based approach , mutual information and other statistical characteristics of a large number of words to the new word recognition , but the statistics derived from the law by the terminology material influence , it is difficult to reflect the true characteristics of the structure of the new words and The essence of the law . Therefore , the identification and extraction of new words are still problems to be solved . This paper attempts to extraction of new words is divided into two phases: the identification of the new word prime ; containing the new Morphemic new word extraction . Corresponding to the characteristics of the different stages : First, new words based on the decision tree to identify factors , new words identify factors seen as a binary classification problem , select the word probability of a word , the word part of speech as the description attribute C5 algorithm to build decision trees ; then , to find a new word morpheme based on , learn from the results of the study of the new word word-building , word new words , new words and words compounding rules are constructed , using the rules to extract the two words and words , new words . The experiments show that the extraction method of the new word is feasible .
