Dataset Card for BT11

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.

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

Languages

• Java

Dataset Structure

Data Instances

{
    "index": 20170,
    "identifier": "currentLineHighlight",
    "segmentation": "current Line Highlight"
}

Data Fields

• index : a numerical index.
• identifier : the original identifier.
• segmentation : the gold segmentation for the identifier.

Dataset Creation

• All hashtag segmentation and identifier splitting datasets on this profile have the same basic fields: hashtag and segmentation or identifier and segmentation .

• The only difference between hashtag and segmentation or between identifier and segmentation are the whitespace characters. Spell checking, expanding abbreviations or correcting characters to uppercase go into other fields.

• There is always whitespace between an alphanumeric character and a sequence of any special characters ( such as _ , : , ~ ).

• If there are any annotations for named entity recognition and other token classification tasks, they are given in a spans field.
