For each experiment, we need a dataset that allows to test the stated hypothesis, as well as a baseline dataset which contains the same amount of labelled issues.

Does a repository specific dataset affect the model's performance?

# run baseline-issues benchmark
npm run dataset:vscode:baseline
npm run benchmark

# run vscode-issues benchmark
npm run dataset:vscode
npm run benchmark

Does a (spoken) language specific dataset affect the models perfomrnace?

# run baseline-issues benchmark
npm run dataset:english:baseline
npm run benchmark

# run english-issues benchmark
npm run dataset:english
npm run benchmark

A dataset (with 10k bugs, 10k enhancements and 10k questions) can be downloaded using npm run dataset. The dataset was generated using github archive's which can be accessed through google BigQuery.

Add the query below to your BigQuery console and adjust if needed (e.g., add __label__ prefix to labels, etc.).

SELECT
  label, CONCAT(title, ' ', REGEXP_REPLACE(body, '(\r|\n|\r\n)',' '))
FROM (
  SELECT
    LOWER(JSON_EXTRACT_SCALAR(payload, '$.issue.labels[0].name')) AS label,
    JSON_EXTRACT_SCALAR(payload, '$.issue.title') AS title,
    JSON_EXTRACT_SCALAR(payload, '$.issue.body') AS body
  FROM
    [githubarchive:day.20180201],
    [githubarchive:day.20180202],
    [githubarchive:day.20180203],
    [githubarchive:day.20180204],
    [githubarchive:day.20180205]
  WHERE
    type = 'IssuesEvent'
    AND JSON_EXTRACT_SCALAR(payload, '$.action') = 'closed' )
WHERE 
  (label = 'bug' OR label = 'enhancement' OR label = 'question')
  AND body != 'null';

You need a .env file in order to run the github app. The file should look like this:

GITHUB_CERT=/path/to/cert.private-key.pem
GITHUB_SECRET=123456
GITHUB_APP_ID=123
PORT=3000

Note: When running app in production, environment variables should be provided by host.
