Query Efficiency in Probabilistic XML Models

Summary: Unifies probabilistic XML via p-documents with distributional nodes; analyzes twig queries under value- and object-based semantics. Efficient evaluator for a single tractable family; translations across families and approximate methods for the rest. (summarized by gpt-5-nano on Feb 09 2026)
