SPARQLT and its User-Friendly Interface for Managing and Querying the History of RDF Knowledge Bases
@inproceedings{Gao2015SPARQLTAI, title={SPARQLT and its User-Friendly Interface for Managing and Querying the History of RDF Knowledge Bases}, author={Shi Gao and Muhao Chen and Maurizio Atzori and Jiaqi Gu and Carlo Zaniolo}, booktitle={International Workshop on the Semantic Web}, year={2015} }
As the real world evolves, the information contained in the knowledge bases is updated accordingly and the evolution history of entities and their properties becomes of great interest to users, who thus need effective query tools to explore it. In this paper, we (i) introduce SPARQL and its user-friendly interface for expressing powerful structured queries on the history of RDF knowledge bases, and (ii) overview its underlying query engine that supports efficient evaluation of such queries and…

RDF-TX: A Fast, User-Friendly System for Querying the History of RDF Knowledge Bases
- Computer ScienceEDBT
- 2016
SPARQL T is introduced, a temporal extension of SPARQL that expresses powerful structured queries on temporal RDF graphs, an efficient in-memory query engine that takes advantage of compressed multiversion B+ trees to achieve fast evaluation of SParQL T queries, and a query optimizer that improves selectivity estimation of temporal queries and generates efficient join orders using the statistics of temporal R DF graphs.

This paper proposes the tGRIN index structure that builds a specialized index for temporal RDF that is physically stored in an RDBMS, and shows that even when these efforts are augmented with well known temporal indexes like R+ trees, SR-trees, ST-index, and MAP21, the t GRIN index exhibits superior performance.
