Web Data Extraction using Hybrid Program Synthesis: A Combination of Top-down and Bottom-up Inference
Summary: Hybrid program synthesis unites top-down deductive and bottom-up enumerative inference, enabling concise web data extraction programs from few examples. Semi-supervised approach improves accuracy, reduces example needs, and lowers program complexity; deployed in Power BI. (summarized by gpt-5-nano on Feb 09 2026)
