Legal Advice

Case Description

This case demonstrates a simple legal consultation agent built utilizing RagPlanner. The agent provides legal advice by retrieving relevant provisions from the Civil Law and the Criminal Law, and integrating them with the case background.

The case leverages the embedding and reranking features of DashScope in conjunction with the Qwen llm. Before using this, you need to configure the DASHSCOPE_API_KEY in your environment variables.

Components

For your convenience, we have placed the databases containing the relevant information in this directory. If you want to build the knowledge base from scratch, you can run the following code:

from agentuniverse.base.agentuniverse import AgentUniverse
from agentuniverse.agent.action.knowledge.knowledge_manager import KnowledgeManager


if __name__ == '__main__':
    AgentUniverse().start(config_path='../../config/config.toml', core_mode=True)
    civil_store_list = ["civil_law_sqlite_store", "civil_law_chroma_store"]
    criminal_store_list = ["criminal_law_sqlite_store", "criminal_law_chroma_store"]
    law_knowledge = KnowledgeManager().get_instance_obj("law_knowledge")
    law_knowledge.insert_knowledge(
        source_path="../resources/刑法.pdf",
        stores=criminal_store_list
    )
    law_knowledge.insert_knowledge(
        source_path="../resources/民法典.pdf",
        stores=civil_store_list
    )
