These small changes (that retain default behavior) will allow a user to create a Zapier tool using the ZapierNLARunTool while providing their own base prompt. Their prompt must contain input fields for zapier_description and params, checked and enforced in the tool's root validator. An example of when this may be useful: user has several, say 10, Zapier tools enabled. Currently, the long generic default Zapier base prompt is attached to every single tool, using an extreme number of tokens for no real added benefit (repeated). User prompts LLM on how to use Zapier tools once, then overrides the base prompt. Or: user has a few specific Zapier tools and wants to maximize their success rate. So, user writes prompts/descriptions for those tools specific to their use case, and provides those to the ZapierNLARunTool. A consideration - this is the simplest way to implement this I could think of... though ideally custom prompting would be possible at the Toolkit level as well. For now, this should be sufficient in solving the concerns outlined above. --- langchain/tools/zapier/tool.py | 12 ++++++- tests/unit_tests/tools/test_zapier.py | 52 +++++++++++++++++++++++++++ 2 files changed, 63 insertions(+), 1 deletion(-) create mode 100644 tests/unit_tests/tools/test_zapier.py diff --git a/langchain/tools/zapier/tool.py b/langchain/tools/zapier/tool.py index f68a3562f7a..cb1fc29544c 100644 --- a/langchain/tools/zapier/tool.py +++ b/langchain/tools/zapier/tool.py @@ -105,6 +105,7 @@ class ZapierNLARunAction(BaseTool): api_wrapper: ZapierNLAWrapper = Field(default_factory=ZapierNLAWrapper) action_id: str params: Optional[dict] = None + base_prompt: str = BASE_ZAPIER_TOOL_PROMPT zapier_description: str params_schema: Dict[str, str] = Field(default_factory=dict) name = "" @@ -116,8 +117,17 @@ class ZapierNLARunAction(BaseTool): params_schema = values["params_schema"] if "instructions" in params_schema: del params_schema["instructions"] + + # Ensure base prompt (if overrided) contains necessary input fields + necessary_fields = {"{zapier_description}", "{params}"} + if not all(field in values["base_prompt"] for field in necessary_fields): + raise ValueError( + "Your custom base Zapier prompt must contain input fields for " + "{zapier_description} and {params}." + ) + values["name"] = zapier_description -

Previously, even if a User-Agent was specified in `header_template`, it would always be overridden by a random User-Agent generated by the `fake_useragent` library. With this change, if a User-Agent is specified in `header_template`, it will be used. Only in the case where no User-Agent is specified will a random User-Agent be generated and used. This provides additional flexibility when using the `WebBaseLoader` class, allowing users to specify their own User-Agent if they have a specific need or preference, while still providing a reasonable default for cases where no User-Agent is specified. This change has no impact on existing users who do not specify a User-Agent, as the behavior in this case remains the same. However, for users who do specify a User-Agent, their choice will now be respected and used for all subsequent requests made using the `WebBaseLoader` class.

Recentadvancesindocumentimageanalysis(DIA)havebeen\\nprimarily driven by the application of neural networks.

However, various factors like loosely organized codebases\\nand sophisticated model configurations complicate the easy reuse of im-\\n2v84351.3012:viXra portantinnovationsbyawideaudience.Thoughtherehavebeenon-going\\nefforts to improve reusability and simplify deep learning (DL) model\\ndevelopmentindisciplineslikenaturallanguageprocessingandcomputer\\nvision, none of them are optimized for challenges in the domain of DIA.\\nThis represents a major gap in the existing toolkit, as DIA is central to\\nacademicresearchacross awiderangeof disciplinesinthesocialsciences\\nand humanities. This paper introduces LayoutParser, an open-source\\nlibrary for streamlining the usage of DL in DIA research and applica-\\ntions. The core LayoutParser library comes with a set of simple and\\nintuitiveinterfacesforapplyingandcustomizingDLmodelsforlayoutde-\\ntection,characterrecognition,andmanyotherdocumentprocessingtasks.\\nTo promote extensibility, LayoutParser also incorporates a community\\nplatform for sharing both pre-trained models and full document digiti-\\nzation pipelines.

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.
