The can be sampled from a database the filtered based on heuristic rule. A geolocation entity unstructured extracted module. with geoentities uploaded onto crowd sourcing platform to manually annotate label. text classification model built learned label machine learning algorithm classified by classifier in order extract user location. then transformed into geocode so that spatial search enabled distance between locations easily calculated.
