A subcategorization study of the premodifiers in english noun phrases 英語名詞短語中前置修飾語的次范疇化研究
Now the automatic acquisition method for sentence level chinese verb subcategorization has many disadvantages . categorizing acquisition precision is not very high 現(xiàn)有的句子級別的漢語動詞次范疇信息(簡稱scf )獲取技術(shù)還存在很多不足之處,分類獲取精度不高。
Verb subcategorization information , mainly coding the types of distribution of predicative features , is indispensable knowledge for further development in the field of natural language processing 動詞次范疇化信息反映了動詞作謂詞時所表現(xiàn)出來的不同句法特征的分布,作為自然語言處理進一步發(fā)展所不可或缺的知識,漢語中的相關(guān)研究還很薄弱。
But the research related chinese researches seem still weak , working on large real corpus faced automatic acquisition methods for sentence level chinese verb subcategorization is of great theoretical significance and practical potentiality 探索面向真實語料的漢語動詞次范疇化自動獲取方法對于中文信息處理來說具有重要的理論研究意義和廣闊的應用前景。
Based on previous achievements of other researches , this thesis analyzes the chinese verb subcategorization in the sentence structures , explores many related algorithms , acquires large real corpus faced sentence level chinese verb subcategorization information automatically , and improves the acquisition precision 本文在國內(nèi)外已有相關(guān)成果的基礎(chǔ)上,對句子結(jié)構(gòu)中包含的次范疇信息進行分析,探索各類相關(guān)算法,對面向真實語料的句子級別漢語動詞次范疇信息進行分類獲取,提高其獲取精度。
Through the experiment , we test its feasibility . 3 、 to solve the insufficiency of the svm method , the thesis proposes another algorithm based on similarity computing for verb subcategorization acquisition , and use two different sentences similarity getting algorithms to the acquisition : vector space model and the algorithm for sentence structure similarity getting that based on word class cluster 3 、針對支持向量機方法在自動獲取性能方面的不足,探索提出了基于相似度計算的動詞次范疇獲取算法,并分別使用了兩種不同的句子相似度獲取算法:向量空間模型和基于詞類串句子結(jié)構(gòu)相似度獲取算法,用于動詞次范疇類獲取。
百科解釋
In linguistics, subcategorization denotes the ability/necessity for lexical items (usually verbs) to require/allow the presence and types of the syntactic arguments with which they co-occur.Chomsky (1965) is a prominent early source on the concept of subcategorization.
