COLM 2026 Workshop on Context Beyond the Window2026Deploying LLMs for enterprise Text-to-SQL is bottlenecked less by the model than by what context reaches it: business logic spans thousands of tables, and no model can ingest a full catalog at once. We argue that the most effective place to intervene is therefore the knowledge-base context the model consumes, and that this context should be constructed from historical usage rather than tuned for as a fixed

COLM 2026 Workshop on Agent Behavior2026Single-metric task-success scores systematically misrank LLM agents in domain-specific deployments: two configurations can achieve identical end-to-end accuracy while exhibiting structurally different production behaviors — silent argument hallucination, infinite tool loops, redundant retries, semantically-equivalent-but-syntactically-divergent queries. We propose a behavioral evaluation protocol that decomposes

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
