Dataset Description

• Paper: Helpful or Not? An investigation on the feasibility of identifier splitting via CNN-BiLSTM-CRF

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.

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

Besides identifier segmentation, the gold labels for this dataset also include abbreviation expansion.

Data Instances

{
    "index": 3,
    "identifier": "abspath",
    "segmentation": "abs path",
    "expansion": "absolute path",
    "spans": {
        "text": [
            "abs"
        ],
        "expansion": [
            "absolute"

        "end": [

        ]
    }
}

Data Fields

• index: a numerical index.
• identifier: the original identifier.
• segmentation: the gold segmentation for the identifier, without abbreviation expansion.
• expansion: the gold segmentation for the identifier, with abbreviation expansion.
• spans: the start and end index of each abbreviation, the text of the abbreviation and its corresponding expansion.

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.
