# Dataset Card for The Loyola University of Delaware Identifier Splitting Oracle

## Dataset Description

- **Repository:** [Loyola University of Delaware Identifier Splitting Oracle](http://www.cs.loyola.edu/~binkley/ludiso/)
- **Paper:** [An empirical study of identifier splitting techniques](https://dl.acm.org/doi/10.1007/s10664-013-9261-0)

### 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.

The Loyola University of Delaware Identifier Splitting Oracle is a dataset for identifier segmentation, 
i.e. the task of adding spaces between the words on a identifier.

### Languages

- Java
- C
- C++
