社交网络谣言是严重危害社会安全的一个重要问题.目前的谣言检测方法基本上都依赖用户评论数据.为了获取可供模型训练的足量评论数据,需要任由谣言在社交平台上传播一段时间,这就扩大了谣言的危害.本文提出了一种基于知识图谱表示学习的谣言检测方法.该方法不依赖用户评论数据.首先基于PN-KG2REC算法得到实体和关系的表示;然后将待检测三元组中的实体和关系表示进行拼接,得到三元组表示;最后对三元组的向量表示进行分类,并根据分类结果判断待检测三元组描述内容的真假性.采用公开数据的实验结果表明,本文提出的谣言检测方法在不依赖用户评论数据的前提下,能够有效地对谣言进行早期检测.
Rumor on social network is an important issue that seriously harms social security. At present
most machine learning based rumor detection methods use comment data as auxiliary information for rumor detection
aiming to achieve higher accuracy. However
in order to obtain enough comment data for training models
it is inevitable that rumors will spread on social platforms for a period of time
which further expands the harm. This paper proposes a rumor detection method based on knowledge graph representation learning. This method uses the facts in the knowledge graph to detect rumors instead of relying on comment data. This method first obtains the representations of entities and relations based on proposed algorithm PN-KG2REC; and then concatenates the representations of entity and relation to obtain the representations of triplets; finally
it determines the authenticity of the contents described by the triplets according to the classification results. Experimental results show that the proposed method can effectively detect rumors without relying on comment posts in the early.
