Anthropic has proposed a method to improve document retrieval by prepending a context generated by an LLM to each chunk. This technique, detailed in a September 2024 write-up, aims to enhance the relevance of search results by providing surrounding information for isolated text segments. When tested, this contextualization reduced retrieval failures by 49% on average, with an additional reranker improving this to a 67% reduction. The method is particularly beneficial for chunks that rely on external context, such as those referencing previous sections or tables. AI
