We automatically build and recommend tags when a user is in the process of uploading photos to Flickr.
For eg: When a user uploads a photo and tags it with "holi", we recommend
the tags: "celebration", "color" "india".
We find that the recommended tags generated, can also be used as query suggestions for Flickr search queries.
How it is done:
1. We take an input tag provided by the user
and get all the other tags that co-occur with this tag.
2. The most frequent co-occuring tags are then presented to the user in an intuitive manner to help her during the photo upload processs.
