# Docugami
This page covers how to use [Docugami](https://docugami.com) within LangChain.
## What is Docugami?
Docugami converts business documents into a Document XML Knowledge Graph, generating forests of XML semantic trees representing entire documents. This is a rich representation that includes the semantic and structural characteristics of various chunks in the document as an XML tree.
## Quick start
1. Create a Docugami workspace: http://www.docugami.com (free trials available)
2. Add your documents (PDF, DOCX or DOC) and allow Docugami to ingest and cluster them into sets of similar documents, e.g. NDAs, Lease Agreements, and Service Agreements. There is no fixed set of document types supported by the system, the clusters created depend on your particular documents, and you can [change the docset assignments](https://help.docugami.com/home/working-with-the-doc-sets-view) later.
3. Create an access token via the Developer Playground for your workspace. Detailed instructions: https://help.docugami.com/home/docugami-api
4. Explore the Docugami API at https://api-docs.docugami.com/ to get a list of your processed docset IDs, or just the document IDs for a particular docset.
6. Use the DocugamiLoader as detailed in [this notebook](../modules/indexes/document_loaders/examples/docugami.ipynb), to get rich semantic chunks for your documents.
7. Optionally, build and publish one or more [reports or abstracts](https://help.docugami.com/home/reports). This helps Docugami improve the semantic XML with better tags based on your preferences, which are then added to the DocugamiLoader output as metadata. Use techniques like [self-querying retriever](https://python.langchain.com/en/latest/modules/indexes/retrievers/examples/self_query_retriever.html) to do high accuracy Document QA.
# Advantages vs Other Chunking Techniques
Appropriate chunking of your documents is critical for retrieval from documents. Many chunking techniques exist, including simple ones that rely on whitespace and recursive chunk splitting based on character length. Docugami offers a different approach:
1. **Intelligent Chunking:** Docugami breaks down every document into a hierarchical semantic XML tree of chunks of varying sizes, from single words or numerical values to entire sections. These chunks follow the semantic contours of the document, providing a more meaningful representation than arbitrary length or simple whitespace-based chunking.
2. **Structured Representation:** In addition, the XML tree indicates the structural contours of every document, using attributes denoting headings, paragraphs, lists, tables, and other common elements, and does that consistently across all supported document formats, such as scanned PDFs or DOCX files. It appropriately handles long-form document characteristics like page headers/footers or multi-column flows for clean text extraction.
3. **Semantic Annotations:** Chunks are annotated with semantic tags that are coherent across the document set, facilitating consistent hierarchical queries across multiple documents, even if they are written and formatted differently. For example, in set of lease agreements, you can easily identify key provisions like the Landlord, Tenant, or Renewal Date, as well as more complex information such as the wording of any sub-lease provision or whether a specific jurisdiction has an exception section within a Termination Clause.
4. **Additional Metadata:** Chunks are also annotated with additional metadata, if a user has been using Docugami. This additional metadata can be used for high-accuracy Document QA without context window restrictions. See detailed code walk-through in [this notebook](../modules/indexes/document_loaders/examples/docugami.ipynb).

# OpenWeatherMap API
This page covers how to use the OpenWeatherMap API within LangChain.
It is broken into two parts: installation and setup, and then references to specific OpenWeatherMap API wrappers.
## Installation and Setup
- Install requirements with `pip install pyowm`
- Go to OpenWeatherMap and sign up for an account to get your API key [here](https://openweathermap.org/api/)
- Set your API key as `OPENWEATHERMAP_API_KEY` environment variable
## Wrappers
### Utility
There exists a OpenWeatherMapAPIWrapper utility which wraps this API. To import this utility:
```python
from langchain.utilities.openweathermap import OpenWeatherMapAPIWrapper
```
For a more detailed walkthrough of this wrapper, see [this notebook](../modules/agents/tools/examples/openweathermap.ipynb).
### Tool
You can also easily load this wrapper as a Tool (to use with an Agent).
You can do this with:
```python
from langchain.agents import load_tools
tools = load_tools(["openweathermap-api"])
```
For more information on this, see [this page](../modules/agents/tools/getting_started.md)

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.
This module is aimed at making this easy.
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.
A primary driver of a lot of this is the `Unstructured <https://github.com/Unstructured-IO/unstructured>`_ python package.
This package is a great way to transform all 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>`_.
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.

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.

The retriever therefore ends up finding unrelated chunks from other documents not even related to the **Menlo Group** landlord. That landlord happens to be mentioned on the first page of the file **Shorebucks LLC_NJ.pdf** file, and while one of the source chunks used by the chain is indeed from that doc that contains the correct answer (**13,500**), other source chunks from different docs are included, and the answer is therefore incorrect."

This paper introduces LayoutParser, an open-source\\nlibrary for streamlining the usage of DL in DIA research and applica-\\ntions.
