AJAX: An Extensible Data Cleaning Tool

Summary: AJAX is an extensible data-cleaning tool that models programs as a directed graph of transformations (mapping, similarity-based matching, clustering, merging) via a declarative SQL-like language. It offers interactive execution and debugging, demonstrated on telecom consolidation and bibliographic normalization. (summarized by gpt-5-nano on Feb 09 2026)
