Transaction Fee Estimation in the Bitcoin System
Limeng Zhang, Rui Zhou, Qing Liu +2
In the Bitcoin system, transaction fees serve as an incentive for blockchain confirmations. In general, a transaction with a higher fee is likely to be included in the next block m…
Searching Personalized -wing in Large and Dynamic Bipartite Graphs
Aman Abidi, Lu Chen, Rui Zhou +1
There are extensive studies focusing on the application scenario that all the bipartite cohesive subgraphs need to be discovered in a bipartite graph. However, we observe that, for…
Efficiently Finding a Maximal Clique Summary via Effective Sampling
Xiaofan Li, Rui Zhou, Lu Chen +3
Maximal clique enumeration (MCE) is a fundamental problem in graph theory and is used in many applications, such as social network analysis, bioinformatics, intelligent agent syste…
Efficient Exact Algorithms for Maximum Balanced Biclique Search in Bipartite Graphs
Lu Chen, Chengfei Liu, Rui Zhou +2
Given a bipartite graph, the maximum balanced biclique (\textsf{MBB}) problem, discovering a mutually connected while equal-sized disjoint sets with the maximum cardinality, plays…
Index-based Solutions for Efficient Density Peak Clustering
Zafaryab Rasool, Rui Zhou, Lu Chen +2
Density Peak Clustering (DPC), a popular density-based clustering approach, has received considerable attention from the research community primarily due to its simplicity and fewe…
Finding Effective Geo-Social Group for Impromptu Activity with Multiple Demands
Lu Chen, Chengfei Liu, Rui Zhou +2
Geo-social group search aims to find a group of people proximate to a location while socially related. One of the driven applications for geo-social group search is organizing an i…
Fine-Grained Emotion Classification of Chinese Microblogs Based on Graph Convolution Networks
Yuni Lai, Linfeng Zhang, Donghong Han +2
Microblogs are widely used to express people's opinions and feelings in daily life. Sentiment analysis (SA) can timely detect personal sentiment polarities through analyzing text.…
Efficient Truss Maintenance in Evolving Networks
Rui Zhou, Chengfei Liu, Jeffrey Xu Yu +2
Truss was proposed to study social network data represented by graphs. A k-truss of a graph is a cohesive subgraph, in which each edge is contained in at least k-2 triangles within…
Query-driven Frequent Co-occurring Term Extraction over Relational Data using MapReduce
Jianxin Li, Chengfei Liu, Liang Yao +2
In this paper we study how to efficiently compute \textit{frequent co-occurring terms} (FCT) in the results of a keyword query in parallel using the popular MapReduce framework. Ta…
Quasi-SLCA based Keyword Query Processing over Probabilistic XML Data
Jianxin Li, Chengfei Liu, Rui Zhou +1
The probabilistic threshold query is one of the most common queries in uncertain databases, where a result satisfying the query must be also with probability meeting the threshold…
ELCA Evaluation for Keyword Search on Probabilistic XML Data
Rui Zhou, Chengfei Liu, Jianxin Li +1
As probabilistic data management is becoming one of the main research focuses and keyword search is turning into a more popular query means, it is natural to think how to support k…
