| # Dataset: `dataset.jsonl` |
|
|
| Auto-labeled commit dataset scraped from GitHub repositories. Each line is a JSON object representing one commit with extracted features and an inferred label. |
|
|
| ## Features |
|
|
| | Field | Type | Description | Stats | |
| |---|---|---|---| |
| | `text` | string | Commit message first line, conventional prefix stripped | — | |
| | `files_count` | int | Number of files changed | mean 4.3, median 1, max 300 | |
| | `additions` | int | Lines added | mean 88, median 6, max 187K | |
| | `deletions` | int | Lines deleted | mean 172, median 3, max 2.3M | |
| | `changed_tests` | int | Files matching test/spec patterns | mean 0.4, median 0, max 286 | |
| | `changed_docs` | int | Files matching doc/documentation patterns | mean 0.6, median 0, max 300 | |
| | `changed_source` | int | Files with known source extensions | mean 2.3, median 1, max 300 | |
| | `has_tests` | bool | Any file in test/spec directory | — | |
| | `has_docs` | bool | Any file in docs directory | — | |
| | `extensions` | [string] | Unique file extensions in the diff | 592 unique | |
|
|
| Top extensions: `md`, `go`, `cc`, `js`, `h`, `json`, `ts`, `yml`, `rc`, `mm` |
|
|
| | `directories` | [string] | Unique top-level directories in the diff | 61 unique | |
|
|
| Top directories: `docs`, `pkg`, `shell`, `atom`, `spec`, `lib`, `test`, `script` |
|
|
| | `label` | string | Inferred commit category | see distribution above | |
|
|
| ## Labeling heuristics |
|
|
| Labels are inferred from the commit message and file changes using a cascade of signals: |
|
|
| ### Conventional commit prefix (highest confidence) |
| ``` |
| fix(scope): → bugfix |
| feat(scope): → feature |
| chore(scope): → chore |
| refactor(scope):→ refactor |
| docs(scope): → docs |
| test(scope): → test |
| perf(scope): → perf |
| ci(scope): → ci |
| build(scope): → build |
| style(scope): → style |
| revert(scope): → revert |
| ``` |
|
|
| ### Gitmoji prefix |
| ``` |
| :bug: → bugfix |
| :sparkles: → feature |
| :books: → docs |
| :hammer: → refactor |
| ... → (28 emoji mapped) |
| ``` |
|
|
| ### Keyword start (first word) |
| ``` |
| fix/correct → bugfix (unless "lint"→chore, "typo"→docs, docs-only→docs) |
| doc/readme → docs |
| add/new/support → feature |
| remove/cleanup → refactor |
| update/bump → chore |
| test/spec → test |
| revert/rollback → revert |
| ``` |
|
|
| ### Free-text keyword (within the whole first line) |
| ``` |
| crash/corrupt/leak/deadlock → bugfix |
| prevent/avoid/guard → bugfix |
| cleanup/tidy/polish → refactor |
| renam/move → refactor |
| refactor/restruct/redesign/rewrite→ refactor |
| ``` |
|
|
| ### File-only fallback |
| - All files in docs directories → `docs` |
| - All files in test/spec directories → `test` |
|
|
