# CompWoB+

CompWoB+ is our extension of the [CompWoB benchmark](https://openreview.net/forum?id=Y9kAsYIjYc), which evaluates language-model agents on sequential compositions of web-automation tasks. Building on the compositional setting introduced by CompWoB, CompWoB+ adds 60 newly constructed HTML environments, with each environment combining three to eight atomic web tasks.

## Dataset Contents

```text
CompWoB-Plus/
├── README.md
├── tasks.jsonl
└── html/
    └── Gen-*.html
```

- `html/` contains the 60 fixed benchmark environments.
- `tasks.jsonl` provides one metadata record for each HTML environment.
- Each composition length from three through eight contains 10 environments.

| Number of subtasks | Environments |
| ---: | ---: |
| 3 | 10 |
| 4 | 10 |
| 5 | 10 |
| 6 | 10 |
| 7 | 10 |
| 8 | 10 |
| **Total** | **60** |

## Metadata Schema

Each line of `tasks.jsonl` is a JSON object with the following fields:

| Field | Type | Description |
| --- | --- | --- |
| `task_id` | string | Unique environment identifier and HTML file stem |
| `html_file` | string | Relative path to the corresponding HTML environment |
| `num_subtasks` | integer | Number of atomic tasks in the composition |
| `subtasks` | list of strings | Ordered atomic-task sequence |
| `split` | string | Dataset split; currently all fixed environments belong to `test` |

Example:

```json
{
  "task_id": "Gen-three_click-button_enter-time_edit-text",
  "html_file": "html/Gen-three_click-button_enter-time_edit-text.html",
  "num_subtasks": 3,
  "subtasks": ["click-button", "enter-time", "edit-text"],
  "split": "test"
}
```

## Usage

These HTML files depend on the MiniWoB+/ComputerGym runtime and are not standalone webpages. For dependency installation, environment integration, the evaluation protocol, and runnable code, refer to the [TTED GitHub repository](GITHUB_REPOSITORY_URL_PLACEHOLDER).

## Citation

If you use CompWoB+, please cite our TTED article, *Learning Simple Test-Time Environments for LLM Web Agents*:
