RTSKG: Building a Rail Transit Station Knowledge Graph Dataset
Shutong Zhu, Tianxing Wu, Runfeng Liu +3
Rail transit systems play a vital role in urban mobility and economic development. As key components of such systems, rail transit stations function as critical transport hubs that…
K-DeCore: Facilitating Knowledge Transfer in Continual Structured Knowledge Reasoning via Knowledge Decoupling
Yongrui Chen, Yi Huang, Yunchang Liu +5
Continual Structured Knowledge Reasoning (CSKR) focuses on training models to handle sequential tasks, where each task involves translating natural language questions into structur…
KGroot: Enhancing Root Cause Analysis through Knowledge Graphs and Graph Convolutional Neural Networks
Tingting Wang, Guilin Qi, Tianxing Wu
Fault localization is challenging in online micro-service due to the wide variety of monitoring data volume, types, events and complex interdependencies in service and components.…
Embedding Ontologies via Incorporating Extensional and Intensional Knowledge
Keyu Wang, Guilin Qi, Jiaoyan Chen +2
Ontologies contain rich knowledge within domain, which can be divided into two categories, namely extensional knowledge and intensional knowledge. Extensional knowledge provides in…
Random Walk-based Community Key-members Search over Large Graphs
Yuxiang Wang, Yuyang Zhao, Xiaoliang Xu +3
Given a graph , a query node , and an integer , community search (CS) seeks a cohesive subgraph (measured by community models such as -core or -truss) from that…
Outlining and Filling: Hierarchical Query Graph Generation for Answering Complex Questions over Knowledge Graphs
Yongrui Chen, Huiying Li, Guilin Qi +2
Query graph construction aims to construct the correct executable SPARQL on the KG to answer natural language questions. Although recent methods have achieved good results using ne…
Efficiently Embedding Dynamic Knowledge Graphs
Tianxing Wu, Arijit Khan, Melvin Yong +2
Knowledge graph (KG) embedding encodes the entities and relations from a KG into low-dimensional vector spaces to support various applications such as KG completion, question answe…
Semantic Guided and Response Times Bounded Top-k Similarity Search over Knowledge Graphs
Yuxiang Wang, Arijit Khan, Tianxing Wu +2
Recently, graph query is widely adopted for querying knowledge graphs. Given a query graph , the graph query finds subgraphs in a knowledge graph that exactly or approxima…
