Unstructured
This page covers how to use Unstructured within LangChain.
What is Unstructured?
Unstructured is an open source Python package
for extracting text from raw documents for use in machine learning applications. Currently,
Unstructured supports partitioning Word documents (in .doc
or .docx
format),
PowerPoints (in .ppt
or .pptx
format), PDFs, HTML files, images,
emails (in .eml
or .msg
format), epubs, markdown, and plain text files.
unstructured
is a Python package and cannot be used directly with TS/JS, Unstructured
also maintains a REST API to support
pre-processing pipelines written in other programming languages. The endpoint for the
hosted Unstructured API is https://api.unstructured.io/general/v0/general
, or you can run
the service locally using the instructions found
here.
Quick start
You can use Unstructured inlangchainjs
with the following code.
Replace the filename with the file you would like to process.
If you are running the container locally, switch the url to
https://api.unstructured.io/general/v0/general
.
import { UnstructuredLoader } from "langchain/document_loader";
const loader = new UnstructuredLoader(
"https://api.unstructured.io/general/v0/general",
"langchain/src/document_loaders/tests/example_data/example.txt"
);
const docs = await loader.load();
Stayed tuned for future updates, including functionality equivalent to
UnstructuredDirectoryLoader
in langchain
!.
