|
|
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.
|
|
|
|
BT11 is a dataset for identifier segmentation,
|
|
i.e. the task of adding spaces between the words on a identifier.
