Document Loaders
==========================

.. note::
   `Conceptual Guide <https://docs.langchain.com/docs/components/indexing/document-loaders>`_


Combining language models with your own text data is a powerful way to differentiate them.
The first step in doing this is to load the data into "Documents" - a fancy way of say some pieces of text.
The document loader is aimed at making this easy.


The following document loaders are provided:


Transform loaders
------------------------------

These **transform** loaders transform data from a specific format into the Document format.
For example, there are **transformers** for CSV and SQL.
Mostly, these loaders input data from files but sometime from URLs.

A primary driver of a lot of these transformers is the `Unstructured <https://github.com/Unstructured-IO/unstructured>`_ python package.
This package transforms many types of files - text, powerpoint, images, html, pdf, etc - into text data.

For detailed instructions on how to get set up with Unstructured, see installation guidelines `here <https://github.com/Unstructured-IO/unstructured#coffee-getting-started>`_.

Public dataset or service loaders
----------------------------------
These datasets and sources are created for public domain and we use queries to search there
and download necessary documents.
For example, **Hacker News** service.

We don't need any access permissions to these datasets and services.

   ./document_loaders/examples/wikipedia.ipynb
   ./document_loaders/examples/youtube_transcript.ipynb


Proprietary dataset or service loaders
------------------------------
These datasets and services are not from the public domain.
These loaders mostly transform data from specific formats of applications or cloud services,
for example **Google Drive**.

We need access tokens and sometime other parameters to get access to these datasets and services.
