Constraint-Safe Graph-Context Scoring for Stable Point-Feature Labels Under Text-Width and Accessibility-Inspired Profiles
Researchers present LABELSENSE-Pilot, a reproducible prototype for optimal point-feature label placement on interactive maps, balancing geometric validity, display yield, and accessibility requirements. The system uses a multilayer perceptron to score layout candidates and ensures viewport containment, uniqueness, and clearance. Experiments demonstrate improved performance over a handcrafted integer program, with reduced flicker and display loss.
