To address these issues, the authors introduce Libem, a compound AI toolchain designed for EM. Libem is modular, allowing for data preprocessing, external information retrieval, and self-refinement through learning and optimization. It adapts to different datasets and performance goals, improving accuracy and ease of use. Initial experiments demonstrate Libem's superiority over solo-AI systems, with an average F1 score increase of 3% across four out of five datasets. The project is ongoing, focusing on enhancing tools, speed, self-refinement, and expanding its application to broader data management tasks. Libem is open-source and aims to enhance practical compound AI solutions for entity matching.
