研究人员开发了SeedER，一个旨在高效导航和提取知识图谱信息的新型检索框架。SeedER解决了快速的自我图谱扩展以及密集嵌入方法在复杂查询中的局限性等挑战。该框架采用两阶段过程：首先使用轻量级检索来确定核心节点，然后采用通过强化学习训练的、可学习的、感知图谱的策略来选择性地扩展相关节点集。 AI
影响 引入了一种新颖的知识图谱检索方法，有望提高知识密集型推理系统的效率和召回率。
排序理由 该集群包含一篇详细介绍新知识图谱检索方法的学术论文。

Knowledge graphs (KGs) offer a rich representation for relational knowledge, but their irregular structure makes retrieval challenging: ego-graph expansion grows rapidly, and dense embedding methods struggle with multi-hop compositional queries. Existing agent-based graph explora…
