From Enumeration to Covering: Near-Optimal Densest P-Partite Subgraph Search over Large Heterogeneous Information Networks
Lu Chen, Chengfei Liu, Rui Zhou +2
Given a heterogeneous information network (HIN) and a query meta-path P of length i, the densest P-partite subgraph problem finds the subgraph, spanning the i typed layers of P, th…
TKHist: Cardinality Estimation for Join Queries via Histograms with Dominant Attribute Correlation Finding
Renrui Li, Qingzhi Ma, Jiajie Xu +2
Cardinality estimation has long been crucial for cost-based database optimizers in identifying optimal query execution plans, attracting significant attention over the past decades…
Consistent and Invariant Generalization Learning for Short-video Misinformation Detection
Hanghui Guo, Weijie Shi, Mengze Li +8
Short-video misinformation detection has attracted wide attention in the multi-modal domain, aiming to accurately identify the misinformation in the video format accompanied by the…
Zero-Shot Cellular Trajectory Map Matching
Weijie Shi, Yue Cui, Hao Chen +5
Cellular Trajectory Map-Matching (CTMM) aims to align cellular location sequences to road networks, which is a necessary preprocessing in location-based services on web platforms l…
Towards DS-NER: Unveiling and Addressing Latent Noise in Distant Annotations
Yuyang Ding, Dan Qiao, Juntao Li +4
Distantly supervised named entity recognition (DS-NER) has emerged as a cheap and convenient alternative to traditional human annotation methods, enabling the automatic generation…
Reliable Community Search in Dynamic Networks
Yifu Tang, Jianxin Li, Nur Al Hasan Haldar +3
Searching for local communities is an important research problem that supports advanced data analysis in various complex networks, such as social networks, collaboration networks,…
Trajectory-Based Spatiotemporal Entity Linking
Fengmei Jin, Wen Hua, Thomas Zhou +4
Trajectory-based spatiotemporal entity linking is to match the same moving object in different datasets based on their movement traces. It is a fundamental step to support spatiote…
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…
Deep Cross Networks with Aesthetic Preference for Cross-domain Recommendation
Jian Liu, Pengpeng Zhao, Yanchi Liu +5
When purchasing appearance-first products, e.g., clothes, product appearance aesthetics plays an important role in the decision process. Moreover, user's aesthetic preference, whic…
Where to Go Next: A Spatio-temporal LSTM model for Next POI Recommendation
Pengpeng Zhao, Haifeng Zhu, Yanchi Liu +3
Next Point-of-Interest (POI) recommendation is of great value for both location-based service providers and users. Recently Recurrent Neural Networks (RNNs) have been proved to be…
