Dataset Description

Dataset Summary

CodeXGLUE code-to-text dataset, available at https://github.com/microsoft/CodeXGLUE/tree/main/Code-Text/code-to-text

The dataset we use comes from CodeSearchNet and we filter the dataset as the following:

  • Remove examples that codes cannot be parsed into an abstract syntax tree.
  • Remove examples that #tokens of documents is < 3 or >256
  • Remove examples that documents contain special tokens (e.g. <img ...> or https:...)
  • Remove examples that documents are not English.

Supported Tasks and Leaderboards

  • machine-translation: The dataset can be used to train a model for automatically generating English docstrings for code.

Languages

  • Go programming language
  • Java programming language
  • Javascript programming language
  • PHP programming language
  • Python programming language
  • Ruby programming language
  • English natural language

field name type description
id int32 Index of the sample
repo string repo: the owner/repo
path string path: the full path to the original file
func_name string func_name: the function or method name
original_string string original_string: the raw string before tokenization or parsing
language string language: the programming language name
code string code/function: the part of the original_string that is code
code_tokens Sequence[string] code_tokens/function_tokens: tokenized version of code
docstring string docstring: the top-level comment or docstring, if it exists in the original string
docstring_tokens Sequence[string] docstring_tokens: tokenized version of docstring
sha string sha of the file
url string url of the file
