Abstract
The present disclosure provides systems and methods that enable map search recommendations based on a geo-semantic index developed using image content analysis. In one example, a computer-implemented method can include obtaining, by one or more computing devices, a vocabulary of image feature types associated with user activities. The method can include obtaining a collection of imagery. The method can include performing image content analysis on the collection of imagery based on the vocabulary of image feature types. The method can include generating at least one activity score for each of a plurality of location cells in a geo-semantic index based at least in part on the vocabulary of image feature types. The method can include populating the geo-semantic index of location cells, the geo-semantic index of location cells including data indicative of the at least one activity score for each location cell. The method can include providing the geo-semantic index of location cells for use in generating location recommendations in response to a query.
