An Efficient Approach for Discovering Graph Entity Dependencies (GEDs)
Dehua Liu, Selasi Kwashie, Yidi Zhang +6
Graph entity dependencies (GEDs) are novel graph constraints, unifying keys and functional dependencies, for property graphs. They have been found useful in many real-world data qu…
Evaluating Hybrid Graph Pattern Queries Using Runtime Index Graphs
Xiaoying Wu, Dimitri Theodoratos, Nikos Mamoulis +1
Graph pattern matching is a fundamental operation for the analysis and exploration ofdata graphs. In thispaper, we presenta novel approachfor efficiently finding homomorphic matche…
Discovering Closed and Maximal Embedded Patterns from Large Tree Data
Xiaoying Wu, Dimitri Theodoratos, Nikos Mamoulis
We address the problem of summarizing embedded tree patterns extracted from large data trees. We do so by defining and mining closed and maximal embedded unordered tree patterns fr…
Design Issues of JPQ: a Pattern-based Query Language for Document Databases
Xuhui Li, Mengchi Liu, Xiaoying Wu +1
Document databases are becoming popular, but how to present complex document query to obtain useful information from the document remains an important topic to study. In this paper…
