    Knowledge Graphs as the Missing Data Layer for LLM-Based Industrial Asset Operations

    Madhulatha Mandarapu, Sandeep Kunkunuru

    cs.DB · cs.AI · cs.LG

    LLM-based agents for industrial asset operations show limited accuracy when reasoning over flat document stores. AssetOpsBench (KDD 2026) establishes that GPT-4 agents achieve 65% on 139 industrial maintenance scenarios backed by CouchDB, YAML, and CSV. It compares LLM orchestration paradigms (Agent-As-Tool vs Plan-Execute) on a fixed data layer; we ask a complementary, orthogonal question: how much does the data model behind the tools affect...

    RT-RkNN: Reverse k Nearest Neighbor Queries as a Graphics Ray Casting Problem

    Zhengyang Bai, Peng Chen, Mohamed Wahib

    cs.DB · cs.DC

    Reverse k nearest neighbor (RkNN) queries are fundamental in spatial databases, location-based analytics, and recommendation systems. Existing state-of-the-art techniques rely on spatial pruning supported by R-trees and their variants. However, their pruning effectiveness degrades significantly in challenging scenarios where the number of facilities is small, the user population is dense, or the value of k is large. To overcome these...
