CSVLoader( file_path: str | Path, source_column: str | None = None, metadata_columns: Sequence[str] = (), csv_args: Dict | None = None, encoding: str | None = None, autodetect_encoding: bool = False, *, content_columns: Sequence[str] = (), ) [source] # Load a CSV file into a list of Documents. Each row of the CSV file is translated to one document. length_function: Function determining the chunk size. Overlapping chunks helps to mitigate loss of information when context is divided between chunks. Overview Document splitting is often a crucial preprocessing step for many applications. One of the dilemmas we saw from just doing these May 22, 2024 · In the world of AI and language models, LangChain stands out as a powerful framework for managing and Tagged with ai, langchain, chunking. Each document represents one row of Overview Document splitting is often a crucial preprocessing step for many applications. Each line of the file is a data record. If embeddings are sufficiently far apart, chunks are split. chunk_overlap: Target overlap between chunks. I first had to convert each CSV file to a LangChain document, and then specify which fields should be the primary content and which fields should be the metadata. This process offers several benefits, such as ensuring consistent processing of varying document lengths, overcoming input size limitations of models, and improving the quality of text representations used in retrieval systems.
