Soos3D	0b4a51930c	Add how to use a custom scraping function with the sitemap loader. (#5847 ) Hi! I just added an example of how to use a custom scraping function with the sitemap loader. I recently used this feature and had to dig in the source code to find it. I thought it might be useful to other devs to have an example in the Jupyter Notebook directly. I only added the example to the documentation page. @eyurtsev I was not able to run the lint. Please let me know if I have to do anything else.

Lance Martin	4092fd21dc	YoutubeAudioLoader and updates to OpenAIWhisperParser (#5772 ) This introduces the `YoutubeAudioLoader`, which will load blobs from a YouTube url and write them. Blobs are then parsed by `OpenAIWhisperParser()`, as show in this [PR](https://github.com/hwchase17/langchain/pull/5580), but we extend the parser to split audio such that each chuck meets the 25MB OpenAI size limit. As shown in the notebook, this enables a very simple UX: ``` # Transcribe the video to text loader = GenericLoader(YoutubeAudioLoader([url],save_dir),OpenAIWhisperParser()) docs = loader.load() ``` Tested on full set of Karpathy lecture videos: ``` # Karpathy lecture videos urls = ["https://youtu.be/VMj-3S1tku0" "https://youtu.be/PaCmpygFfXo", "https://youtu.be/TCH_1BHY58I", "https://youtu.be/P6sfmUTpUmc", "https://youtu.be/q8SA3rM6ckI", "https://youtu.be/t3YJ5hKiMQ0", "https://youtu.be/kCc8FmEb1nY"] # Directory to save audio files save_dir = "~/Downloads/YouTube" # Transcribe the videos to text loader = GenericLoader(YoutubeAudioLoader(urls,save_dir),OpenAIWhisperParser()) docs = loader.load() ```	1 year ago

berkedilekoglu	f907b62526	Scores are explained in vectorestore docs (#5613 ) # Scores in Vectorestores' Docs Are Explained Following vectorestores can return scores with similar documents by using `similarity_search_with_score`: - chroma - docarray_hnsw - docarray_in_memory - faiss - myscale - qdrant - supabase - vectara - weaviate However, in documents, these scores were either not explained at all or explained in a way that could lead to misunderstandings (e.g., FAISS). For instance in FAISS document: if we consider the score returned by the function as a similarity score, we understand that a document returning a higher score is more similar to the source document. However, since the scores returned by the function are distance scores, we should understand that smaller scores correspond to more similar documents. For the libraries other than Vectara, I wrote the scores they use by investigating from the source libraries. Since I couldn't be certain about the score metric used by Vectara, I didn't make any changes in its documentation. The links mentioned in Vectara's documentation became broken due to updates, so I replaced them with working ones.

Finally, we'd love to show appreciation for your contribution - if you'd like us to shout you out on Twitter, please also include your handle! --> #### Description This PR is mainly to integrate open source version of ClickHouse as Vector Store as it is easy for both local development and adoption of LangChain for enterprises who already have large scale clickhouse deployment. ClickHouse is a open source real-time OLAP database with full SQL support and a wide range of functions to assist users in writing analytical queries. Some of these functions and data structures perform distance operations between vectors, [enabling ClickHouse to be used as a vector database](https://clickhouse.com/blog/vector-search-clickhouse-p1). Recently added ClickHouse capabilities like [Approximate Nearest Neighbour (ANN) indices](https://clickhouse.com/docs/en/engines/table-engines/mergetree-family/annindexes) support faster approximate matching of vectors and provide a promising development aimed to further enhance the vector matching capabilities of ClickHouse. In LangChain, some ClickHouse based commercial variant vector stores like [Chroma](https://github.com/hwchase17/langchain/blob/master/langchain/vectorstores/chroma.py) and [MyScale](https://github.com/hwchase17/langchain/blob/master/langchain/vectorstores/myscale.py), etc are already integrated, but for some enterprises with large scale Clickhouse clusters deployment, it will be more straightforward to upgrade existing clickhouse infra instead of moving to another similar vector store solution, so we believe it's a valid requirement to integrate open source version of ClickHouse as vector store. As `clickhouse-connect` is already included by other integrations, this PR won't include any new dependencies. #### Before submitting <!-- If you're adding a new integration, please include: 1. Added a test for the integration: https://github.com/haoch/langchain/blob/clickhouse/tests/integration_tests/vectorstores/test_clickhouse.py 2.

Chandan Routray	bc875a9df1	Fixed multi input prompt for MapReduceChain (#4979 ) # Fixed multi input prompt for MapReduceChain Added `kwargs` support for inner chains of `MapReduceChain` via `from_params` method Currently the `from_method` method of intialising `MapReduceChain` chain doesn't work if prompt has multiple inputs. It happens because it uses `StuffDocumentsChain` and `MapReduceDocumentsChain` underneath, both of them require specifying `document_variable_name` if `prompt` of their `llm_chain` has more than one `input`. With this PR, I have added support for passing their respective `kwargs` via the `from_params` method. ## Fixes https://github.com/hwchase17/langchain/issues/4752 ## Who can review? @dev2049 @hwchase17 @agola11 --------- Co-authored-by: imeckr <chandanroutray2012@gmail.com>	1 year ago
Matt Robinson	a97e4252e3	feat: add `UnstructuredExcelLoader` for `.xlsx` and `.xls` files (#5617 ) # Unstructured Excel Loader Adds an `UnstructuredExcelLoader` class for `.xlsx` and `.xls` files. Works with `unstructured>=0.6.7`. A plain text representation of the Excel file will be available under the `page_content` attribute in the doc. If you use the loader in `"elements"` mode, an HTML representation of the Excel file will be available under the `text_as_html` metadata key. Each sheet in the Excel document is its own document. ### Testing ```python from langchain.document_loaders import UnstructuredExcelLoader loader = UnstructuredExcelLoader( "example_data/stanley-cups.xlsx", mode="elements" ) docs = loader.load() ``` ## Who can review? @hwchase17 @eyurtsev	1 year ago
