Optimizing Multi-query Evaluation in Federated RDF Systems
收藏 引用
IEEE TRANSACTIONS ON KNOWLEDGE AND DATA ENGINEERING 2021年 第4期33卷 1692-1707页
作者: Peng, Peng Ge, Qi Zou, Lei Ozsu, M. Tamer Xu, Zhiwei Zhao, Dongyan Hunan Univ Changsha 410082 Hunan Peoples R China Peking Univ Haidian 100871 Peoples R China Univ Waterloo Waterloo ON N2L 3G1 Canada
This paper revisits the classical problem of multiple query optimization in federated RDF systems. We propose a heuristic query rewriting-based approach to optimize the evaluation of multiple queries. This approach ca... 详细信息
