  • Methods and systems of venue inference for social messages
    Patent number: 10395179
    Abstract: A method for inferring venues from social messages includes: accessing a collection of venues and training a classifier that predicts whether a social message is linked to a venue in the collection of venues; receiving a new social message; for each venue in the collection of venues: identifying for the new social message corresponding meta-paths to the particular venue; encoding the corresponding meta-paths as a feature vector for the trained classifier; computing by the trained classifier a score for each venue in the collection of venues indicating whether the new social message is linked to the venue; and based on the scores, identifying at least one candidate venue as a predicted venue for the new social message and associating the predicted venue with the new social message. In some implementations, the new social message is not geotagged.
