Description

This pull request introduces a new feature that integrates the LangChain library into our project. Specifically, it adds a Retrieval Augmented Generation (RAG) tool to the common_tools module, which can be used for question-answering tasks by retrieving relevant information from a knowledge base and generating a final answer.

The changes in the portal directory are related to the front-end implementation of the RAG tool. The Home.tsx file has been updated to include a new component that allows users to interact with the RAG tool. The CommonLayout.tsx file has been modified to include the necessary imports and styling for the new component. Additionally, the types/index.ts file has been updated to include any new type definitions required for the RAG tool.

The package.json and package-lock.json files have been updated to include the LangChain library as a dependency.

Type of change

• New feature (non-breaking change which adds functionality)
• Bug fix (non-breaking change which fixes an issue)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• This change requires a documentation update

Description

This pull request introduces a new feature that integrates the LangChain library into our application. The primary change is in the rag.py file, which implements the Retrieval Augmented Generation (RAG) model from LangChain. This model combines a retrieval component with a language model to provide more accurate and relevant responses.

Additionally, there are changes to the frontend codebase to support the new RAG functionality. The Home.tsx file has been updated to include a new component for interacting with the RAG model. Corresponding changes have been made to the locale files (en.json and zh.json) to provide translations for the new UI elements.

The package.json and package-lock.json files have been updated to include the required LangChain dependencies.

Description

This pull request includes changes to integrate the LangChain library for natural language processing tasks, specifically the Retrieval Augmented Generation (RAG) model. The RAG model is a powerful tool that combines a retrieval system with a language model to generate high-quality text based on relevant information retrieved from a knowledge base.

The main changes are:

1. rag.py: Modified to include the RAG model implementation and related utilities.
2. package-lock.json and package.json: Updated to include the required dependencies for the LangChain library.
3. CommonLayout.tsx, en.json, zh.json, Home.tsx, and index.ts: Modified to integrate the RAG model into the user interface and handle user interactions.

The motivation behind this change is to enhance the application's natural language processing capabilities by leveraging the power of the RAG model. This will enable more accurate and relevant text generation based on the available knowledge base, leading to an improved user experience.

No additional dependencies are required for this change beyond the updated package.json.
