摘　　要：检测长文本和短文本相似性的应用场景越来越多,文本对的一致性检测大多可以统一抽象成文本相似性的比较问题。该问题的难点在于短文本是零散的,从而很难判断其属于哪个领域及其背景知识,也难以引入词嵌入来解决在通用场景的具体文本匹配问题。基于这个问题,提出一种新的基于文本聚类主题模型的轻量方法,不需要利用额外的背景知识来匹配通用文本相似性。在两个经典测试样本数据集上的实验结果表明,该方法的文本相似性检测效率非常高。The similarity measurement between a long text and a short text relatively has more and more application scenarios,and the consistency judgment on these text pairs can be abstracte as a comparison problem of text similarity.The challenge is that the short text is sparse,it is difficult to determine which domain it belongs to and it is also difficult to introduce word embedding to solve the specific text matching problem in general scenarios.Aiming at this problem,this paper proposes a lightweight approach based on topic model with text clustering which can match generalized longshort texts without using extra related background knowledge.The experimental results on two typical test sample datasets show the text similarity detection efficiency of the proposed method is very high.
