Oct 1, 2025October 2025 monthly summary for JohnSnowLabs/spark-nlp: Delivered high-impact features and reliability improvements with a strong focus on data quality, traceability, and developer UX. Key features delivered include selective entity extraction via EntityRuler (extractEntities parameter), AutoMode presets for cleaning and extraction across DocumentNormalizer and EntityRuler, hierarchical HTML parsing with HTMLReader (element IDs and parent IDs) and preserved metadata in Reader2Doc, sentence-level propagation of input metadata, and Notebook UX updates (Colab links and notebook version metadata). These changes enhance extraction accuracy, consistency, and end-user notebook experience while strengthening test coverage and maintainability. Major bugs fixed / stability improvements include metadata preservation in sentence detectors, metadata propagation through Reader2Doc tests, and corrected Colab links ensuring reproducible notebook launches, contributing to more reliable data pipelines and smoother developer workflows.
