Based on the dependency syntax tree library of LTP language Cloud system of Harbin Institute of Technology,this paper explores the syntactic features of bullet screen language from three aspects:dependency type,dependency distance and dependency direction percentage.It is found that the dependency types of bullet screen language are mainly in the form of the relationship,the subject-predicate relationship,the right attachment relationship,the fixed middle relationship and the verb-object relationship.The sentences of bullet screen language are short,mainly simple sentences,supplemented by complex sentences;The sentence length of a single sentence is concentrated within 1-5 words,and the sentence length of a complex sentence is concentrated within 10-15 words.The average dependency distance of single complex sentences in bullet screen language increases slowly with the increase of sentence length,and there is a significant correlation between them.The dependent direction of bullet screen language is mainly manifested as the dominant word after.
