Common-Neighbor-Count-Based Representative Possible World Finding on Uncertain Graphs
Chengjie Gu, Xiaoliang Xu, Yuxiang Wang +5
A representative possible world (RPW) is a deterministic graph derived from an uncertain graph where a designated structural feature closely approximates its expected…
Directory-Aware Query and Maintenance in Vector Databases
Mengzhao Wang, Zheng Gong, Jingpei Hu +4
Vector databases typically manage metadata as flat scalar attributes, which limits their ability to express hierarchical directory semantics commonly used to organize code reposito…
Balancing the Blend: An Experimental Analysis of Trade-offs in Hybrid Search
Mengzhao Wang, Boyu Tan, Yunjun Gao +5
Hybrid search, the integration of lexical and semantic retrieval, has become a cornerstone of modern information retrieval systems, driven by demanding applications like Retrieval-…
