jackeet/RuBirdNames

Examples of 583 handwritten words (not counting words produced by mistake) that make up the common names of 701 bird species found in Russia. Original bird names were produced using eBird's API.

The dataset contains examples of handprinted and cursive scripts as well as various backgrounds (plain white, grid-ruled paper, line-ruled paper).

There are currently 21325 images, that is, at least 35 full sets of 583 words. Some of the words have up to 38 different image examples. The sets are distinguished by image numbers, that is, all images named 001 belong to the first set.

All the examples were produced by 30-40 volunteers. Some of the sets were written by the same people, but using different hands, writing styles, or backgrounds. Some sets were written by several writers.

The labels for each image can be extracted from the corresponding directory name. The corrections.csv file contains extra labels for words written with some kind of mistake, e.g. 'адвокат' instead of 'авдотка', 'орел' instead of 'орёл' and so on.
