Visa Requirement Checker
detail.loadingPreview
A workflow to check visa requirements based on user input, leveraging Langchain, Cohere embeddings, Weaviate vector store, and Anthropic LLM.
About This Workflow
This workflow automates the process of checking visa requirements. It receives input via a webhook, processes the information using Langchain, stores and retrieves relevant data from a Weaviate vector store, and generates an answer using an Anthropic language model. The results are logged to a Google Sheet.
Key Features
- Webhook Integration: Accepts visa requirement queries via an HTTP POST request.
- Text Splitting: Divides incoming text into manageable chunks for processing.
- AI Embeddings: Utilizes Cohere for generating embeddings to represent text semantically.
- Vector Store: Stores and queries visa-related information efficiently using Weaviate.
- Conversational AI: Employs Anthropic's language model for natural language understanding and response generation.
- Tool Integration: Connects the vector store as a tool for the AI agent.
- Memory Management: Maintains conversational context with a buffer window.
- Agentic Behavior: Orchestrates the interaction between tools, memory, and the language model.
- Logging: Records workflow execution and results to a Google Sheet.
How To Use
- Trigger: Send a POST request to the
/visa_requirement_checkerwebhook endpoint with the query. - Processing: The
Splitternode will chunk the input. - Embedding & Storage:
EmbeddingsCoheregenerates embeddings, andvectorStoreWeaviate(Insert mode) stores them in the 'visa_requirement_checker' index. - Querying:
vectorStoreWeaviate(Query mode) retrieves relevant information based on the input. - Tooling: The retrieved vector store data is exposed as a tool (
ToolVectorStore). - Memory:
MemoryBufferWindowmaintains conversation history. - LLM Interaction:
lmChatAnthropicgenerates a response using the tools and memory. - Agent Orchestration: The
Agentnode directs the flow, utilizing the tools and memory to answer the query. - Logging: The final output is appended to the 'Log' sheet in the specified Google Sheet.
