Hybrid Retrieval

Hybrid retrieval methods combine the strengths of different information retrieval approaches, such as sparse lexical methods and dense semantic embeddings, to improve the accuracy and efficiency of retrieving relevant information from large datasets. Current research focuses on developing hybrid architectures that effectively integrate diverse data sources (e.g., audio, metadata, knowledge graphs) and leverage techniques like contrastive learning and parameter adaptation to optimize retrieval performance. These advancements are significantly impacting various applications, including legal and policy analysis, product question answering, and personalized recommendations, by enhancing the accuracy and efficiency of information access and improving the interpretability of retrieval models.
