Researchers have developed new methods for sequential recommendation systems that leverage rich semantic information from product reviews and item attributes. One approach, ASER, uses a fine-tuned large language model to extract sensory attributes from reviews, distilling them into embeddings that enhance recommendation accuracy. Another method, CAST, models semantic-level transitions and incorporates LLM-verified complementary priors to better identify true item complementarity, outperforming existing models and offering significant training acceleration.
