REAL: A Reasoning-Enhanced Graph Framework for Long-Term Memory Management of LLMs
Keer Lu, Liwei Chen, Guoqing Jiang +3
Large Language Models (LLMs) are increasingly expected to interact with users over long time horizons. However, due to their finite context window, LLMs cannot retain all past inte…
CroPS: Improving Dense Retrieval with Cross-Perspective Positive Samples in Short-Video Search
Ao Xie, Jiahui Chen, Quanzhi Zhu +4
Dense retrieval has become a foundational paradigm in modern search systems, especially on short-video platforms. However, most industrial systems adopt a self-reinforcing training…
UniDex: Rethinking Search Inverted Indexing with Unified Semantic Modeling
Zan Li, Jiahui Chen, Yuan Chai +11
Inverted indexing has traditionally been a cornerstone of modern search systems, leveraging exact term matches to determine relevance between queries and documents. However, this t…
UniSearch: Rethinking Search System with a Unified Generative Architecture
Jiahui Chen, Xiaoze Jiang, Zhibo Wang +18
Modern search systems play a crucial role in facilitating information acquisition. Traditional search engines typically rely on a cascaded architecture, where results are retrieved…
Personalized Query Auto-Completion for Long and Short-Term Interests with Adaptive Detoxification Generation
Zhibo Wang, Xiaoze Jiang, Zhiheng Qin +2
Query auto-completion (QAC) plays a crucial role in modern search systems. However, in real-world applications, there are two pressing challenges that still need to be addressed. F…
