什么是时序知识图谱问答(Temporal Knowledge Graph Question Answering,TKGQA)? 给定时序知识图谱 G 和一个自然语言表述的时序问题 q,TKGQA任务的目标是使用来自 G 的一组实体 {e∣e∈E}或时间戳 {τ∣τ∈T} 来回答问题 q。 问题 时序问题分类上的模糊性 缺乏对现有方法的系统分类两种分类 基于语义解析(SP-...
时态知识图谱问答(Temporal Knowledge Graph Question Answering, TKGQA)。给定时态知识图谱 G 和一个自然语言表述的时态问题 q,TKGQA 任务的目标是使用来自 G 的一组实体 {e | e ∈ E} 或时间戳 {τ | τ∈ T} 来回答问题 q。 这段文字定义了时态知识图谱问答的任务,即如何利用时态知识图谱中的信息来...
Question Answering Over Temporal Knowledge Graphs (TKGQA) is an important topic in question answering. TKGQA focuses on accurately understanding questions involving temporal constraints and retrieving accurate answers from knowledge graphs. In previous research, the hierarchical structure of question contexts...

In the last few years, the availability of temporal knowledge graphs (TKGs), which associate time information for each event, increased the need for completing in these TKGs. In order to solve the completion problem, the existing efforts extend static knowledge graph completion models to handle ti...
