doccano is an open source text annotation tool for humans. It provides annotation features for text classification, sequence labeling and sequence to sequence tasks. So, you can create labeled data for sentiment analysis, named entity recognition, text summarization and so on. Just create a project, upload data and start annotating. You can build a dataset in hours.
## Demo
You can try the [annotation demo](http://doccano.herokuapp.com).
## Features
- Collaborative annotation

## Usage
Three options to run doccano:
- pip(experimental)
- Docker
- Docker Compose
- production
- development
For docker and docker compose, you need to install dependencies:
- [Git](https://git-scm.com)
- [Docker](https://www.docker.com)
- [Docker Compose](https://docs.docker.com/compose)
### pip installation
To install doccano, simply run:
```bash
pip install doccano
```
After installation, simply run the following command:
```bash
# Initialize database.
doccano init
# Create a super user.
doccano createuser --username admin --password pass
# Start the webserver.
doccano webserver --port 8000
```
And in another terminal, run the following command:
```bash
# Start the task queue.
doccano task
```
Go to .
### Docker
As a one-time setup, create a Docker container as follows:
```bash
docker pull doccano/doccano
docker container create --name doccano \
-e "ADMIN_USERNAME=admin" \
-e "ADMIN_EMAIL=admin@example.com" \
-e "ADMIN_PASSWORD=password" \
-p 8000:8000 doccano/doccano
```
Next, start doccano by running the container:
```bash
docker container start doccano
```
To stop the container, run `docker container stop doccano -t 5`.
All data created in the container will persist across restarts.
Go to .
### Docker Compose
You need to clone the repository:
```bash
git clone https://github.com/doccano/doccano.git
cd doccano
```
_Note for Windows developers:_ Be sure to configure git to correctly handle line endings or you may encounter `status code 127` errors while running the services in future steps. Running with the git config options below will ensure your git directory correctly handles line endings.
```bash
git clone https://github.com/doccano/doccano.git --config core.autocrlf=input
```
#### Production
Set the superuser account credentials in the `docker-compose.prod.yml` file:
```yml
ADMIN_USERNAME: "admin"
ADMIN_PASSWORD: "password"
```
If you use Google Analytics, set the tracking:
```yml
GOOGLE_TRACKING_ID: "UA-12345678-1"
```
Run doccano:
```bash
$ docker-compose -f docker-compose.prod.yml --env-file ./config/.env.example up
```
Go to .
#### Development
Set the superuser account credentials in the `docker-compose.dev.yml` file:
```yml
ADMIN_USERNAME: "admin"
ADMIN_PASSWORD: "password"
```
Run Doccano:
```bash
$ docker-compose -f docker-compose.dev.yml --env-file ./config/.env.example up
```
Go to .
Run Backend API-Tests:
You can run the API-Tests for the backend with the following command:
```bash
docker exec doccano_backend_1 pipenv run app/manage.py test api
```
