ACM SIGSPATIAL 20262026Accurate map paths are crucial for routing vehicles, pedestrians, and autonomous systems, yet keeping that data fresh demands continual editing of features and geometry, and labeling of attributes such as surface type and lane count. At scale this is labor-intensive, and each change calls for spatial reasoning and verification that has resisted full automation, keeping a human in the loop. We present MapScout

ACM SIGSPATIAL 20262026Last-mile logistics efficiency largely depends on map data being accurate, fresh, and having high geospatial coverage. Operators must preserve these qualities when migrating between heterogeneous map data providers. Existing work in the literature addresses road-geometry conflation; however, the conflation of road network attributes and their transition relations remains under-studied, especially at a production-level

CIKM 20262026Production search indices operate under strict storage and latency budgets that prevent indexing the full corpus (e.g.: web documents). When only a fraction of documents can be retained, the system must decide which ones to keep. Existing pruning methods make this decision using query-agnostic signals, including lexical quality, embedding magnitude, and corpus centrality or single-feature query-aware heuristics

RecSys 20262026Off-policy evaluation ( OPE) estimates the performance of new recommendation policies using logged data, thus enabling fast, safe and inexpensive iteration prior to costly A/B tests. To evaluate ranking policies, existing OPE estimators all make structural assumptions about user behavior, leading to a spectrum of trade-offs between bias and variance. The recently proposed INTERPOL estimator navigates these

2026RAG systems are increasingly used to summarize what large collections of documents say. A user asks “What do people think about X?” and receives an answer that reads as consensus. But standard top-k retrieval ranks documents by query similarity, not by how faithfully they represent the population, so minority views quietly disappear. Existing fixes fall short. Diversity re-rankers like MMR and DPP spread
