Worked on the xerrors/Yuxi-Know repository to stabilize and enhance content chunking for improved retrieval reliability and cross-platform consistency. Addressed a bug that preserved context within lists and math blocks, ensuring accurate content block retrieval. Enhanced the semantic chunking tool by optimizing NLTK data handling to avoid redundant downloads, standardize resource management, and clarify error reporting. Leveraged Docker and Python to mount NLTK data to a named volume via docker-compose, reducing environment-specific inconsistencies. Focused on backend development and data processing, the work also included cleaning test files and improving error messaging, streamlining both developer workflows and search accuracy.
