# Dataset Card for Jhotdraw

## Dataset Description

- **Paper:** [Helpful or Not? An investigation on the feasibility of identifier splitting via CNN-BiLSTM-CRF](https://ksiresearch.org/seke/seke18paper/seke18paper_167.pdf)

### Dataset Summary

In programming languages, identifiers are tokens (also called symbols) which name language entities.
Some of the kinds of entities an identifier might denote include variables, types, labels, subroutines, and packages.

Jhotdraw is a dataset for identifier segmentation, i.e. the task of adding spaces between the words on a identifier.

### Languages

- Java
