ImageNet
ImageNet provided a large dataset for visual recognition.
Why it matters
A shared benchmark made progress in image recognition easier to measure and compare.
A dataset’s labels and collection choices can also shape what a benchmark measures.

The same thesis, embodied in a dataset rather than a paper.
- Contrasts Eighty million images at 32 × 32 2008links to this record
ImageNet sets itself against this collection: here a synset averages 1000 images, 10-25% of them clean; in ImageNet about 99%, at full resolution.
- Enables Mechanical Turk: human work ordered through an API 2005links to this record
The 2010 paper on crowdworkers lists ImageNet among the work done on this marketplace: labelling millions of images became possible because labour could be ordered through an API.

The ImageNet paper calls LabelMe complementary to itself: about 200 categories and 30,000 images, but with the outlines and locations of objects.
- Contrasts The ESP Game: image labels as play 2004links to this record
ImageNet in 2009 compares itself with the ESP dataset: the game's labels sit at the "basic level", do not disambiguate word senses and are public for only 60,000 images.

Web scale as a source of data is the precondition later datasets depended on.
- Related The Penn Treebank 1993links to this record
The same move ImageNet later repeated: a shared labelled set as the condition for progress.
