How Does Zilliz Help With Natural Language Processing?

Developers are transforming Natural Language Processing (NLP) with vector databases, which allow efficient storage and retrieval of NLP model-generated vector embeddings. This innovation simplifies finding similar documents, phrases, or words based on semantic similarity.

Another popular use case of vector databases is Retrieval Augmented Generation (RAG). It is a technique to address the hallucination issues of Large Language Models (LLMs). These models are typically trained on publicly available data and may lack domain-specific or proprietary information. Developers can store such specialized data in a vector database like Milvus, perform a similarity search to find the top-K relevant results and feed these results into the LLM. This approach ensures that the LLM generates accurate responses based on both general and domain-specific information.

Hence, by leveraging Milvus, developers can enhance the capabilities of NLP applications, ensuring more precise and contextually relevant outputs.
