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