docs[patch]: AWS platform page update (#14160)
The `AWS` platform page has many missed integrations.
- added missed integration references to the `AWS` platform page
- added/updated descriptions and links in the referenced notebooks
- renamed two notebook files. They have file names != page Title, which
generate unordered ToC.
- reroute the URLs for renamed files
- fixed `amazon_textract` notebook: removed failed cell outputs

Update Hologres vector store: use hologres-vector (#13767)
Hi,
I made some code changes on the Hologres vector store to improve the
data insertion performance.
Also, this version of the code uses `hologres-vector` library. This
library is more convenient for us to update, and more efficient in
performance.
The code has passed the format/lint/spell check. I have run the unit
test for Hologres connecting to my own database.
Please check this PR again and tell me if anything needs to change.

Best,
Changgeng,
Developer @ Alibaba Cloud

docs: Hugging Face platform page (#13831)
`Hugging Face` is definitely a platform. It includes many integrations
for many modules (LLM, Embedding, DocumentLoader, Tool)
So, a doc page was added that defines Hugging Face as a platform.

Added Slacktoolkit (#14012)
- **Description:** 
This PR introduces the Slack toolkit to LangChain, which allows users to
read and write to Slack using the Slack API. Specifically, we've added
the following tools.
1. get_channel: Provides a summary of all the channels in a workspace.
2. get_message: Gets the message history of a channel.
3. send_message: Sends a message to a channel.
4. schedule_message: Sends a message to a channel at a specific time and
date.

- **Issue:** This pull request addresses [Add Slack Toolkit
#11747](https://github.com/langchain-ai/langchain/issues/11747)
  - **Dependencies:** package`slack_sdk`
Note: For this toolkit to function you will need to add a Slack app to
your workspace. Additional info can be found

Fix: (issue #14066) DOC: Summarization output broken (#14078)
- **Description:** : As described in the issue below, 
https://python.langchain.com/docs/use_cases/summarization  
I've modified the Python code in the above notebook to perform well. 

I also modified the OpenAI LLM model to the latest version as shown
below.
`gpt-3.5-turbo-16k --> gpt-3.5-turbo-1106`
This is because it seems to be a bit more responsive.

Added support for a Pandas DataFrame OutputParser (#13257)
**Description:**

Added support for a Pandas DataFrame OutputParser with format
instructions, along with unit tests and a demo notebook. Namely, we've
added the ability to request data from a DataFrame, have the LLM parse
the request, and then use that request to retrieve a well-formatted
response.

Within LangChain, it seamlessly integrates with language models like
OpenAI's `text-davinci-003`, facilitating streamlined interaction using
the format instructions (just like the other output parsers).

This parser structures its requests as
`<operation/column/row>[<optional_array_params>]`. The instructions
detail permissible operations, valid columns, and array formats,
ensuring clarity and adherence to the required format.

For example:

- When the LLM receives the input: "Retrieve the mean of `num_legs` from
rows 1 to 3."
- The provided format instructions guide the LLM to structure the
request as: "mean:num_legs[1..3]".

The parser processes this formatted request, leveraging the LLM's
understanding to extract the mean of `num_legs` from rows 1 to 3 within
the Pandas DataFrame.

This integration allows users to communicate requests naturally, with
the LLM transforming these instructions into structured commands
understood by the `PandasDataFrameOutputParser`. The format instructions
act as a bridge between natural language queries and precise DataFrame
operations, optimizing communication and data retrieval.

**Issue:**

- https://github.com/langchain-ai/langchain/issues/11532

**Dependencies:**

No additional dependencies :)

Implemented MongoDB Atlas Self-Query Retriever (#13321)
# Description 
This PR implements Self-Query Retriever for MongoDB Atlas vector store.

I've implemented the comparators and operators that are supported by
MongoDB Atlas vector store according to the section titled "Atlas Vector
Search Pre-Filter" from
https://www.mongodb.com/docs/atlas/atlas-vector-search/vector-search-stage/.

Namely:
```
allowed_comparators = [
      Comparator.EQ,
      Comparator.NE,
      Comparator.GT,
      Comparator.GTE,
      Comparator.LT,
      Comparator.LTE,
      Comparator.IN,
      Comparator.NIN,
  ]

"""Subset of allowed logical operators."""
allowed_operators = [
    Operator.AND,
    Operator.OR
]
```
Translations from comparators/operators to MongoDB Atlas filter
operators(you can find the syntax in the "Atlas Vector Search
Pre-Filter" section from the previous link) are done using the following
dictionary:
```
map_dict = {
            Operator.AND: "$and",
            Operator.OR: "$or",
            Comparator.EQ: "$eq",
            Comparator.NE: "$ne",
            Comparator.GTE: "$gte",
            Comparator.LTE: "$lte",
            Comparator.LT: "$lt",
            Comparator.GT: "$gt",
            Comparator.IN: "$in",
            Comparator.NIN: "$nin",
        }
```

In visit_structured_query() the filters are passed as "pre_filter" and
not "filter" as in the MongoDB link above since langchain's
implementation of MongoDB atlas vector
store(libs\langchain\langchain\vectorstores\mongodb_atlas.py) in
_similarity_search_with_score() sets the "filter" key to have the value
of the "pre_filter" argument.
```
params["filter"] = pre_filter
```
Test cases and documentation have also been added.

# Issue
#11616 

# Dependencies
No new dependencies have been added.

# Documentation
I have created the notebook mongodb_atlas_self_query.ipynb outlining the
steps to get the self-query mechanism working.

I worked closely with [@Farhan-Faisal](https://github.com/Farhan-Faisal)
on this PR.

  - **Twitter handle:** None.

  Hello,

This is our first PR and we hope that our changes will be helpful to the
community. We have run `make format`, `make lint` and `make test`
locally before submitting the PR. To our knowledge, our changes do not
introduce any new errors.

Our PR integrates the `praw` package which is already used by
RedditPostsLoader in LangChain. Nonetheless, we have added integration
tests and edited unit tests to test our changes. An example notebook is
also provided. These changes were put together by me, @Anika2000,
@CharlesXu123, and @Jeremy-Cheng-stack

Thank you in advance to the maintainers for their time.

        Relationship properties are the following:
        []
        The relationships are the following:
        ['(:Actor)-[:ACTED_IN]->(:Movie)']

```
Node properties are the following:
Movie {name: STRING},Actor {name: STRING}
Relationship properties are the following:

Small fix to _summarization_ example, `reduce_template` should use
`{docs}` variable.

Bug likely introduced as following code suggests using
`hub.pull("rlm/map-prompt")` instead of defined prompt.

docs[patch]: RAG Cookbook example fix (#13914)
### Description:
Hey 👋🏽  this is a small docs example fix. Hoping it helps future developers  who are working with Langchain.

### Problem:
Take a look at the original example code. You were not able to get the `dialogue_turn[0]` while it was a tuple.

Original code:
```python
def _format_chat_history(chat_history: List[Tuple]) -> str:
    buffer = ""
    for dialogue_turn in chat_history:
        human = "Human: " + dialogue_turn[0]
        ai = "Assistant: " + dialogue_turn[1]
        buffer += "\n" + "\n".join([human, ai])
    return buffer
```
In the original code you were getting this error:
```bash
    human = "Human: " + dialogue_turn[0].content
                        ~~~~~~~~~~~~~^^^
TypeError: 'HumanMessage' object is not subscriptable
```
### Solution:
The fix is to just for loop over the chat history and look to see if its a human or ai message and add it to the buffer.

renamed google_vertex_ai_vector_search notebook (#13484)
The `integrations/vectorstores/matchingengine.ipynb` example has the
"Google Vertex AI Vector Search" title. This place this Title in the
wrong order in the ToC (it is sorted by the file name).
- Renamed `integrations/vectorstores/matchingengine.ipynb` into
`integrations/vectorstores/google_vertex_ai_vector_search.ipynb`.
- Updated a correspondent comment in docstring
- Rerouted old URL to a new URL

docs[patch]: top menu (#13748)
Addressed this issue with the top menu: It allocates too much space. If the screen is small, then the top menu items are split into two lines and look unreadable.
Another issue is with several top menu items: "Chat our docs" and "Also by LangChain". They are compound of several words which also hurts readability. The top menu items should be 1-word size.
Updates:
- "Chat our docs" -> "Chat" (the meaning is clean after clicking/opening the item)
- "Also by LangChain" -> "🦜🔗"
- "🦜🔗" moved before "Chat" item. This new item is partially copied from the first left item, the "🦜🔗 LangChain". This design (with two 🦜🔗 elements, visually splits the top menu into two parts. The first item in each part holds the 🦜🔗 symbols and, when we click the second 🦜🔗 item, it opens the drop-down menu. So, we've got two visually similar parts, which visually split the top menu on the right side: the LangChain Docs (and Doc-related items) and the lift side: other LangChain.ai (company) products/docs.
