# GitHub Repository Event Streams

Curated event sequences from GitHub repositories, designed for temporal point process (TPP) and marked temporal point process (MTPP) modeling. Each sequence captures the development activity of a single repository over a one-week window.

## Dataset Description

- **Source:** [GH Archive](https://www.gharchive.org/) raw JSON dumps
- **Time window:** June 1 - 7, 2024
- **Grouping:** Events grouped by repository
- **Sequences:** 373
- **Sequence length:** 60-80 events per sequence
- **Time unit:** hours
- **Language:** English only

## Schema

Each record is a dictionary with 8 fields:

| Field | Type | Description |
|---|---|---|
| `seq_idx` | int | Sequence index |
| `seq_len` | int | Number of events in the sequence |
| `description` | str | Repository name, description, language, stars, and event window |
| `metadata` | str (JSON) | `repo_name`, `stars`, `language`, `actors`, `time_unit` |
| `time_since_start` | list[float] | Time since the first event (in `time_unit`, default hours) |
| `time_since_last_event` | list[float] | Time since the previous event (in `time_unit`, default hours) |
| `type_event` | list[str] | Event type labels (see below) |
| `type_text` | list[str] | Natural language description of each event |

## Event Types (8 categories)

| Label | Description |
|---|---|
| `issue_opened` | New issue filed |
| `issue_closed` | Issue resolved/closed |
| `pr_opened` | Pull request opened |
| `pr_merged` | Pull request merged |
| `push` | Code pushed (with commit messages) |
| `release` | Release published |
| `pr_reviewed` | PR approved or changes requested |
| `comment` | Comment on issue, PR, or review |

## Curation Filters

Sequences are selected to represent moderately active, well-maintained repositories with balanced development activity:

| Filter | Value | Description |
|---|---|---|
| `min-raw-events` | 50 | Min kept-type events in archive (pre-classification) |
| `max-raw-events` | 300 | Max kept-type events in archive (pre-classification) |
| `min-events` | 60 | Min classified events per sequence |
| `max-events` | 80 | Max classified events (skip, not truncate) |
| `max-bot-fraction` | 0.2 | Skip repos where >20% events are from bots |
| `min-unique-types` | 5 | At least 5 distinct event types |
| `min-avg-text-len` | 150 | Min average text length per event |
| `max-type-fraction` | 0.5 | No single event type >50% of events |
| `min-actors` | 2 | At least 2 unique contributors |
| `max-actors` | 5 | At most 5 unique contributors |
| `require-description` | true | Repo must have a description |
| `require-english` | true | All event texts must be in English (non-Latin script detection) |

## Example

```json
{
  "seq_idx": 0,
  "seq_len": 68,
  "description": "GitHub repository example/repo: A web framework for building APIs (Python, 1,234 stars) Event window: June 01 - 07, 2024.",
  "metadata": "{\"repo_name\": \"example/repo\", \"stars\": \"1234\", \"language\": \"Python\", \"actors\": [\"alice\", \"bob\", \"charlie\"], \"time_unit\": \"hours\"}",
  "time_since_start": [0.0, 0.123, ...],
  "time_since_last_event": [0.0, 0.123, ...],
  "type_event": ["pr_opened", "comment", "pr_reviewed", ...],
  "type_text": ["Pull request opened by alice: Add new RPC endpoint...", ...]
}
```

## Intended Use

- Training and evaluating temporal point process models
- Studying software development workflow patterns
- Benchmarking next-event prediction and event forecasting
- Modeling marked temporal point processes with rich text marks
