Wikipedia Picture of the Day Dataset

[Receive updates on further data collection here]

Wikipedia has a Picture of the day section that presents one (usually beautiful) image per day, with a short paragraph describing the image. The following dataset contains the images and text from Nov 1, 2004 to Feb 2, 2011 *.

Download: Raw images and text (with wikipedia markups): images(226M) text(682k) Preprocessed text: tgz(368k) Parsed data (following the GibbsLDA data format): tgz(1M) Note: Images contained in the dataset are in the public domain. Licenses of individual images may vary. Please refer to corresponding wikipedia POTD pages for more details.

In our ICCV paper, we collected the pictures and text descriptions to train a cross-modal laten topic model. Such a topic model learns cross-modal semantics so that images and text are mapped onto a shared latent space, in which content-based retrieval could be carried out. Below is a sample text query and images returned by our algorithm (top row) and Corr-LDA:

* Our ICCV paper uses only the segment from Nov 1 2004 to Oct 30, 2010.
