Given two place names n1 and n2, and an approximate geographical location containing both of them, determine if the two names can refer to the same entity.
Methods• A novel generative language model for places that identifies the core of
a place name. E.g., it identifies that in “Fresca’s Peruvian Restaurant”, Fresca’s is the core and Peruvian Restaurant is the description.
• A language model that incorporates the spatial context, e.g., the presence of nearby landmarks, parks, malls, airports, major streets and the current city.
• The spatial model helps us with distinguishing “Newpark Mall Gap Outlet” from “Newpark Mall Sears Outlet” and matching/non-matching Central Park and Central Park Cafe.
• A place name similarity measure that incorporates both core-word detection and spatial context to substantially improve precision and recall for place name matching.
