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).

Abstract: A plurality of documents is scored, where at least some of the documents are characterized by at least one link from at least one other of the documents. For each of at least particular ones of the plurality of documents, a score is assigned to that particular document, with respect to a topic, based at least in part on an incoherency characteristic associated with at least one document linking to that particular document.

Abstract: A method that iteratively determines which web pages and web sites are of interest to a particular user in accordance with that user's geographic location or country. The described embodiment of the present invention determines zero or more countrytags for each web page or site considered. The described embodiment makes two passes (iterations) to arrive at these countrytags.
