Large Language Model Enhanced Recommender Systems: A Survey

Understand

Large Language Model (LLM) has transformative potential in various domains, including recommender systems (RS).

• There have been a handful of research that focuses on empowering the RS by LLM.
• However, previous efforts mainly focus on LLM as RS, which may face the challenge of intolerant inference costs by LLM.
• Recently, the integration of LLM into RS, known as LLM-Enhanced Recommender Systems (LLMERS), has garnered significant interest due to its potential to address latency and memory constraints in real-world applications.
