-
On the foundation of pretreatment of language c subject, analyzing three existing similarity model and designing the similarity model of language c subject ; through the introduction of hownet ’ s structure and administrative levels and primitive ’ s similarity method, achieving semantic similarity method of words based on hownet, than advancing semantic similar as hownet to solve the similarity of domain words which are not embodied in hownet ; ulteriorly, through researching existing sentence similarity model and combining it with idiographic subjects, achieving the senntence similarity model towards language c subject library ; finally telling of the similarity model arithmetic ’ s application in language c subject library, then analyzing and estimating the effect of it in order to advance the shortage and expanding direction
在對c語言試題進行預處理的基礎上，分析了現有的三種相似度模型，並設計了c語言試題相似度模型;通過對知網的結構、層次關系以及知網中義原的相似度模型的介紹，實現了基於知網的詞的語義相似度模型，並提出用類似知網的語義詞典來解決知網中沒有收錄的領域詞匯的相似度;進一步地，通過研究現有的語句相似度模型，結合具體題目，實現了面向c語言試題庫的語句相似度模型演算法，最後具體講述了相似度演算法在c語言題庫中的應用，並對該方法的效果進行了客觀的分析和評價，以提出不足和發展方向。
