Title
(EN) Text matching method and device, storage medium and computer equipment
(ZH) 文本匹配方法、装置及存储介质、计算机设备
Abstract
(EN) The invention provides a text matching method and device, a storage medium and computer equipment. The method comprises the steps that receiving an input target text is received; obtaining a pluralityof candidate sentences obtained by preliminary matching according to the target text; inputting the target text and each candidate statement into a text matching model formed by a convolutional neural network CNN and a GRU neural network to obtain semantic similarity between each candidate statement and the target text; wherein the text matching model is used for representing the semantic similarity between the target text and the candidate statement; and recommending the candidate sentences to a user according to the semantic similarity corresponding to each candidate sentence. According tothe method, the sentence with the most semantic matching in the candidate sentences matched with the text can be obtained without manually defining the feature template, and the screening efficiency is improved.
(ZH) 本发明提供一种文本匹配方法、装置及存储介质、计算机设备,所述方法包括:接收输入的目标文本;获取根据所述目标文本进行初步匹配得到的多个候选语句;将所述目标文本与每个所述候选语句输入卷积神经网络CNN与GRU神经网络构成的文本匹配模型,得到每个所述候选语句与所述目标文本的语义相似度;其中,所述文本匹配模型用于表征所述目标文本与所述候选语句的语义相似度;根据每个所述候选语句对应的语义相似度,向用户推荐所述候选语句。上述方法实现无需人工去定义特征模板即可获得文本匹配的候选句中语义最匹配的句子,提供筛选效率。
