CAPTION GENERATION FOR VISUAL MEDIA

Aspects of the technology described herein automatically generate captions for visual media, such as a photograph or video. The caption can be presented to a user for adoption and/or modification. If adopted, the caption could be associated with the image and then forwarded to the user's social network, a group of users, or any individual or entity designated by a user. The caption is generated using data from the image in combination with signal data received from a mobile device on which the visual media is present. The data from the image could be gathered via object identification performed on the image. The signal data can be used to determine a context for the image. The signal data can also help identify other events that are associated with the image, for example, that the user is on vacation. The caption is built using information from both the picture and context.
