Understand

This paper contributes to cross-lingual image annotation and retrieval in terms of data and baseline methods.

  • We propose COCO-CN, a novel dataset enriching MS-COCO with manually written Chinese sentences and tags.
  • For more effective annotation acquisition, we develop a recommendation-assisted collective annotation system, automatically providing an annotator with several tags and sentences deemed to be relevant with respect to the pictorial content.
  • Having 20,342 images annotated with 27,218 Chinese sentences and 70,993 tags, COCO-CN is currently the largest Chinese-English dataset that provides a unified and challenging platform for cross-lingual image tagging, captioning and retrieval.
