提出了一种基于不同语义单元度量的句子相似度计算方法。将句子按词块分割为对应的公共词块和非公共词块，利用外部语义资源进行同义词替换和语义消歧处理。分别用词、词块和字为语义单元度量句子相似度，以不同的权重调节各语义单元对句子相似度的贡献。实验结果表明，该方法综合考虑的因素更加全面，有较高的准确率。
提齣瞭一種基于不同語義單元度量的句子相似度計算方法。將句子按詞塊分割為對應的公共詞塊和非公共詞塊，利用外部語義資源進行同義詞替換和語義消歧處理。分彆用詞、詞塊和字為語義單元度量句子相似度，以不同的權重調節各語義單元對句子相似度的貢獻。實驗結果錶明，該方法綜閤攷慮的因素更加全麵，有較高的準確率。

A method of sentence similarity computing based on different semantic units was proposed .A sentence can be divided into corresponding public word blocks and non-public word blocks according to word blocks , and then synonym substitution and semantic disambiguation processing can be carried by using external semantic resource . Words, word blocks and characters were used as the semantic units to measure the sentence similarity and adjust the contribution of each semantic unit to the sentence similarity with different weights .The experimental results showed that this approach of overall evaluation factor was more comprehensive and higher accuracy can be achieved .
