Abstract: 【Purpose/significance】Statistics and analysis of Chinese word segmentation results of People's Daily corpus in recent years
will help to summarize the rules of ambiguity in Chinese word segmentation in the new era,improve the efficiency of word segmentation, and promote the development of related research and technology of Chinese information processing.【Method/process】This paper takes the four month's corpus of NEPD as the research object,and discusses the segmentation rules of variant words such as nouns,verbs,nu? merals,quantifiers,adverbs,adjectives,distinguishing words,location words,time words,pronouns,prepositions,conjunctions,auxiliary words,idioms,negative words,prefixes/suffixes,etc.through statistics of word frequency,word length and congruence.【Result/conclu? sion】The results show that most of the segmentation variations in the corpus are false ambiguity,and the frequency of entire form of the two-syllable words with the same grammatical structure is higher than the three-syllable words and four-syllable words.【Innova? tion/limitation】For the first time,this paper discusses the ambiguity of Chinese word segmentation in the new era People's Daily cor? pus,but it lacks a comparative analysis with the old corpus.
