FusionQuery: On-demand Fusion Queries over Multi-source Heterogeneous Data

Summary: FusionQuery performs on-demand data fusion using only query-relevant records, avoiding full data-lake scans. It combines line-graph knowledge-graph matching with EM-style veracity/trust estimation and incremental source-trust updates, improving efficiency and effectiveness.
