G3: Geolocation via Guidebook Grounding [PDF]
Conference on Empirical Methods in Natural Language Processing, 2022 We demonstrate how language can improve geolocation: the task of predicting the location where an image was taken. Here we study explicit knowledge from human-written guidebooks that describe the salient and class-discriminative visual features humans ...
