BailianKnowledge

Bailian Cloud Knowledge Base implementation.

This class provides integration with Alibaba Cloud Bailian Knowledge Base service, implementing the Knowledge interface to enable seamless RAG (Retrieval-Augmented Generation) capabilities with cloud-hosted knowledge bases.

Key features:

• Cloud-hosted knowledge base (no local infrastructure needed)

• Automatic document parsing and embedding by Bailian service

• Enterprise-grade search with reranking and filtering

• Supports structured, unstructured, and image knowledge bases

Example usage:

`// 1. Configure Bailian connection
BailianConfig config = BailianConfig.builder()
.accessKeyId(System.getenv("ALIBABA_CLOUD_ACCESS_KEY_ID"))
.accessKeySecret(System.getenv("ALIBABA_CLOUD_ACCESS_KEY_SECRET"))
.workspaceId("llm-xxx")
.indexId("mymxbdxxxx")
.build();

// 2. Create knowledge base instance
BailianKnowledge knowledge = BailianKnowledge.builder()
.config(config)
.build();

// 3. Retrieve documents
RetrieveConfig retrieveConfig = RetrieveConfig.builder()
.limit(5)
.scoreThreshold(0.5)
.build();

List<Document> results = knowledge.retrieve("query text", retrieveConfig).block();

// 4. Use with agents via KnowledgeRetrievalTools
KnowledgeRetrievalTools tools = new KnowledgeRetrievalTools(knowledge);
Toolkit toolkit = new Toolkit();
toolkit.registerObject(tools);

ReActAgent agent = ReActAgent.builder()
.name("Assistant")
.model(chatModel)
.toolkit(toolkit)
.build();
`

Note: Currently, only the retrieve operation is supported via API. Document upload and management must be performed through the Bailian console or will be supported in future releases.
