CheetahGIS: Architecting a Scalable and Efficient Streaming Spatial Query Processing System
Jiaping Cao, Ting Sun, Man Lung Yiu +2
Spatial data analytics systems are widely studied in both the academia and industry. However, existing systems are limited when handling a large number of moving objects and real t…
MHSNet:An MoE-based Hierarchical Semantic Representation Network for Accurate Duplicate Resume Detection with Large Language Model
Yu Li, Zulong Chen, Wenjian Xu +4
To maintain the company's talent pool, recruiters need to continuously search for resumes from third-party websites (e.g., LinkedIn, Indeed). However, fetched resumes are often inc…
Efficient Methods for Accurate Sparse Trajectory Recovery and Map Matching
Wei Tian, Jieming Shi, Man Lung Yiu
Real-world trajectories are often sparse with low-sampling rates (i.e., long intervals between consecutive GPS points) and misaligned with road networks, yet many applications dema…
PolyFit: Polynomial-based Indexing Approach for Fast Approximate Range Aggregate Queries
Zhe Li, Tsz Nam Chan, Man Lung Yiu +1
Range aggregate queries find frequent application in data analytics. In some use cases, approximate results are preferred over accurate results if they can be computed rapidly and…
Shortest Path Computation with No Information Leakage
Kyriakos Mouratidis, Man Lung Yiu
Shortest path computation is one of the most common queries in location-based services (LBSs). Although particularly useful, such queries raise serious privacy concerns. Exposing t…
Discovery of Convoys in Trajectory Databases
Hoyoung Jeung, Man Lung Yiu, Xiaofang Zhou +2
As mobile devices with positioning capabilities continue to proliferate, data management for so-called trajectory databases that capture the historical movements of populations of…
