hMDAP: A Hybrid Framework for Multi-paradigm Data Analytical Processing on Spark
Xiaowang Zhang, Jiahui Zhang, Zhiyong Feng
We propose hMDAP, a hybrid framework for large-scale data analytical processing on Spark, to support multi-paradigm process (incl. OLAP, machine learning, and graph analysis etc.)…
PRSP: A Plugin-based Framework for RDF Stream Processing
Qiong Li, Xiaowang Zhang, Zhiyong Feng
In this paper, we propose a plugin-based framework for RDF stream processing named PRSP. Within this framework, we can employ SPARQL query engines to process C-SPARQL queries with…
Path discovery by Querying the federation of Relational Database and RDF Graph
Xiaowang Zhang, Jiahui Zhang, Muhammad Qasim Yasin +2
The class of queries for detecting path is an important as those can extract implicit binary relations over the nodes of input graphs. Most of the path querying languages used by t…
PIWD: A Plugin-based Framework for Well-Designed SPARQL
Xiaowang Zhang, Zhenyu Song, Zhiyong Feng +1
In the real world datasets (e.g.,DBpedia query log), queries built on well-designed patterns containing only AND and OPT operators (for short, WDAO-patterns) account for a large pr…
Undecidability of satisfiability in the algebra of finite binary relations with union, composition, and difference
Tony Tan, Jan Van den Bussche, Xiaowang Zhang
We consider expressions built up from binary relation names using the operators union, composition, and set difference. We show that it is undecidable to test whether a given such…
