Our model leverages the advantages of Temporal Knowledge Graphs (TKGs) that can capture both the multi-relations and evolution. We begin by modeling user-item interactions over time by constructing a Temporal I
Therefore, the concept of temporal knowledge graphs (TKGs) was proposed by academics. As shown in Fig. 1, there is a sub-graph of a temporal knowledge graph. Similar to static KGs, TKGs also exist incompleteness. Thus, a novel research direction, TKGC (Temporal Knowledge Graph Completion),...
(2022). Additionally, LLMs possess temporal commonsense (Chu et al., 2023), which is often absent in traditional temporal knowledge graphs. This temporal knowledge can complement existing TKGs for TKGQA. 补充知识。语言模型本身可以作为时态知识图谱(TKG)使用,正如Dhingra等人(2022)所展示的那样。此外,...

大多数流行的TKGF基准是从2020年之前构建的TKGs中提取的,例如ICEWS14, ICEWS18和ICEWS05-15[15]。其中的事实是基于2019年之前的世界知识,这意味着LMs可能在其训练语料库中遇到它们,这对lm驱动的TKG推理模型构成了信息泄露的威胁。 模型方法: 上图表示了zrllm增强的TKGF模型说明:(a)培训管道。(b)评价管道。
TKG comprises a sequence of knowledge graphs (KGs) at various timestamps. Presently, existing methodologies tend to either focus solely on learning historical event characteristics or exclusively model time-dependent relationships. There is a notable dearth of research concerning incomplete data, posing ...
Knowledge Graph Completion (KGC) is a fundamental problem for temporal knowledge graphs (TKGs), and TKGs embedding methods are one of the essential methods for KGC. However, existing TKG embedding methods encounter a scalability dilemma, i.e., the inconsistency in parameter scalability among differen...
Temporal reasoning methods have been successful in temporal knowledge graphs (TKGs) and are widely employed in many downstream application areas. Most existing TKG reasoning models transform time intervals into continuous time snapshots, with each snapshot representing a subgraph of the TKG. Although suc...
Reasoning over Temporal Knowledge Graphs (TKGs) aims to predict future facts based on given history. One of the key challenges for prediction is to learn the evolution of facts. Most existing works focus on exploring evolutionary information in history to obtain effective temporal embeddings for enti...
