Query rewriting在检索增强的大型语言模型(RAG)中是一个重要的技术,用于提升检索和生成的效果。 Query rewriting在检索增强的大型语言模型(RAG)中扮演着关键角色,它通过对原始查询进行改写,使其更适合检索器从知识库中检索相关信息,从而提高生成模型的准确性和相关性。以下是关于Query rewriting在RAG中的详细解释: 定义...
we train three kinds of reward models for the above metrics to achieve more efficient training. Finally, we combine the scores of these reward models as feedback, and use PPO algorithm to explore the optimal query rewriting strategy. Experimental results on two conversational RAG datasets demonstrat...

快用 Query Rewriting 优化技术 编者按:在现实生活中,普通用户很难编写合适的提示词(prompt)来指示 LLM 完成期望任务。用户提出的 queries 往往存在词汇不准确、缺乏语义信息等问题,导致 LLM 难以理解并生成相关的模型响应。因此,如何优化 queries ,增强 LLM 对各类 query 信息的精准理解能力,是当前亟待攻克的重要课题...

Many highly useful query understanding techniques, such as synonyms, spell correction, and semantics, belong to the family of queryrewriting, which aims to modify the query to represent the query intent better and thus improve overall precision, recall, or both. The order in which these techniques...
We investigate the experimental effectiveness of query rewriting over XML security views. Our model consists of access control policies specified over DTDs with XPath expression for data-dependent access control policies. We provide the notion of securit
The method may also include selectively rewriting the received search query based on whether the entity name is determined to be associated with a common word or phrase, performing a search based on the received search query or the rewritten search query to obtain search results, and presenting ...
