LLMs predict content expiration for Baidu web search

Researchers have developed a new framework using Large Language Models (LLMs) to predict content expiration in web search, addressing the challenge of information freshness. This approach, deployed in Baidu search, reformulates timeliness as a dynamic validity inference task. By extracting temporal contexts and using LLMs to determine a query-specific "validity horizon," the system aims to provide more relevant and up-to-date search results, showing significant improvements in user experience metrics.

    RAG-Enhanced Large Language Models for Dynamic Content Expiration Prediction in Web Search

    In commercial web search, aligning content freshness with user intent remains challenging due to the highly varied lifespans of information. Traditional industrial approaches rely on static time-window filtering, resulting in "one-size-fits-all" rankings where content may be chro…
