UnstructuredIOChunker

class UnstructuredIOChunker(BaseChunker):
A class for chunking text while respecting structure and character limits. This class ensures that structured elements, such as document sections and titles, are not arbitrarily split across chunks. It utilizes the UnstructuredIO class to process and segment elements while maintaining readability and coherence. The chunking method can be adjusted based on the provided chunk_type parameter. Parameters:
  • chunk_type (str, optional): The method used for chunking text. (default: :obj:"chunk_by_title")
  • max_characters (int, optional): The maximum number of characters allowed per chunk. (default: :obj:500)
  • metadata_filename (Optional[str], optional): An optional filename for storing metadata related to chunking. (default: :obj:None)
