Complex Temporal Question Answering on Knowledge Graphs [PDF]

open access: yesProceedings of the 30th ACM International Conference on Information & Knowledge Management, 2021
Question answering over knowledge graphs (KG-QA) is a vital topic in IR. Questions with temporal intent are a special class of practical importance, but have not received much attention in research. This work presents EXAQT, the first end-to-end system for answering complex temporal questions that have multiple entities and predicates, and associated ...

Diachronic Embedding for Temporal Knowledge Graph Completion

open access: yesProceedings of the AAAI Conference on Artificial Intelligence, 2020
Knowledge graphs (KGs) typically contain temporal facts indicating relationships among entities at different times. Due to their incompleteness, several approaches have been proposed to infer new facts for a KG based on the existing ones–a problem known as KG completion.

Temporal knowledge graph completion:methods and progress

open access: yes大数据, 2021
Temporal knowledge graph (TKG) are obtained by adding the time information of real-world knowledge to classical knowledge graphs.Recently, TKG completion has drawn much attention and become a hot topic in research.Two main methodologies for TKG ...

Towards the specification and verification of modal properties for structured systems [PDF]

open access: yes, 2012
System specification formalisms should come with suitable property specification languages and effective verification tools. We sketch a framework for the verification of quantified temporal properties of systems with dynamically evolving structure.

Temporal Knowledge Graph Completion Using Box Embeddings

open access: yes, 2022
Knowledge graph completion is the task of inferring missing facts based on existing data in a knowledge graph. Temporal knowledge graph completion (TKGC) is an extension of this task to temporal knowledge graphs, where each fact is additionally ...

Unsupervised Entity Alignment for Temporal Knowledge Graphs

open access: yesCoRR, 2023
Entity alignment (EA) is a fundamental data integration task that identifies equivalent entities between different knowledge graphs (KGs). Temporal Knowledge graphs (TKGs) extend traditional knowledge graphs by introducing timestamps, which have received increasing attention.

Extrapolation over temporal knowledge graph via hyperbolic embedding

open access: yesCAAI Transactions on Intelligence Technology, 2023
Predicting potential facts in the future, Temporal Knowledge Graph (TKG) extrapolation remains challenging because of the deep dependence between the temporal association and semantic patterns of facts.
