Geo-ontology extraction from entities with spatial and non-spatial attributes

Abstract

Architecture that provides fully automatic generation of a geo-ontology and does not use pre-existing geo-ontologies or other location entity repositories (e.g., a licensed location). The architecture extracts the formal administrative structure of a geographical region of interest (e.g., country) (a geo-ontology of locations with attributes and relations) from a collection of entities with spatial attributes, extracts the informal administrative structure of a geographical region of interest (e.g., country) (informal administrative regions and names and informal neighborhoods and their attributes), and extracts location static rank features for all these entities (attributes used for ranking locations from the geo-ontology that appear in user queries).
