Leveraging Neighborhood Summaries for Efficient RDF Queries on RDBMS
Lei Gai
Using structural informations to summarize graph-structured RDF data is helpful in tackling query performance issues. However, leveraging structural indexes needs to revise or even…
ROSIE: Runtime Optimization of SPARQL Queries Using Incremental Evaluation
Lei Gai, Wei Chen, Tengjiao Wang
Relational databases are wildly adopted in RDF (Resource Description Framework) data management. For efficient SPARQL query evaluation, the legacy query optimizer needs reconsidera…
A partition-based Summary-Graph-Driven Method for Efficient RDF Query Processing
Lei Gai, Wei Chen, Tengjiao Wang
RDF query optimization is a challenging problem. Although considerable factors and their impacts on query efficiency have been investigated, this problem still needs further invest…
Towards Efficient Path Query on Social Network with Hybrid RDF Management
Lei Gai, Wei Chen, Zhichao Xu +2
The scalability and exibility of Resource Description Framework(RDF) model make it ideally suited for representing online social networks(OSN). One basic operation in OSN is to fin…
Relational Approach for Shortest Path Discovery over Large Graphs
Jun Gao, Ruoming Jin, Jiashuai Zhou +3
With the rapid growth of large graphs, we cannot assume that graphs can still be fully loaded into memory, thus the disk-based graph operation is inevitable. In this paper, we take…
