# AnnotateChange
Welcome to the repository of the "AnnotateChange" application. This
application was created to collect annotations of time series data in order to
construct the [Turing Change Point
Dataset](https://github.com/alan-turing-institute/TCPD) (TCPD). The TCPD is a
dataset of real-world time series used to evaluate change point detection
algorithms. For the change point detection benchmark that was created using
this dataset, see the [Turing Change Point Detection
Benchmark](https://github.com/alan-turing-institute/TCPDBench) repository.Any work that uses this repository should cite our paper: [**Van den Burg &
Williams - An Evaluation of Change Point Detection Algorithms
(2020)**](https://arxiv.org/abs/2003.06222). You can use the following BibTeX
entry:```bib

```Here's a screenshot of what the application looks like during the annotation
process:
Some of the features of AnnotateChange include:
* Admin panel to add/remove datasets, add/remove annotation tasks, add/remove
users, and inspect incoming annotations.* Basic user management: authentication, email confirmation, forgotten
password, automatic log out after inactivity, etc. Users are only allowed to
register using an email address from an approved domain.* Task assignment of time series to user is done on the fly, ensuring no user
ever annotates the same dataset twice, and prioritising datasets that are
close to a desired number of annotations.* Interactive graph of a time series that supports pan and zoom, support for
multidimensional time series.* Mandatory "demo" to onboard the user to change point annotation.
* Backup of annotations to the admin via email.
* Time series datasets are verified upon upload acccording to a strict schema.
## Getting Started
Below are instructions for setting up the application for local development
and for running the application with Docker.### Basic
AnnotateChange can be launched quickly for local development as follows:
1. Clone the repo
```
$ git clone https://github.com/alan-turing-institute/AnnotateChange
$ cd AnnotateChange
```2. Set up a virtual environment and install dependencies (requires Python
3.7+)
```
$ sudo apt-get install -y python3-venv # assuming Ubuntu
$ pip install wheel
$ python3 -m venv ./venv
$ source ./venv/bin/activate
$ pip install -r requirements.txt
```3. Create local development environment file
```
$ cp .env.example .env.development
$ sed -i 's/DB_TYPE=mysql/DB_TYPE=sqlite3/g' .env.development
```
With ``DB_TYPE=sqlite3``, we don't have to deal with MySQL locally.4. Initialize the database (this will be a local ``app.db`` file).
```
$ ./flask.sh db upgrade
```5. Create the admin user account
```
$ ./flask.sh admin add --auto-confirm-email
```
The ``--auto-confirm-email`` flag automatically marks the email address of
the admin user as confirmed. This is mostly useful in development
environments when you don't have a mail address set up yet.6. Run the application
```
$ ./flask.sh run
```
This should tell you where its running, probably ``localhost:5000``. You
should be able to log in with the admin account you've just created.7. As admin, upload **ALL** demo datasets (included in [demo_data](./demo_data))
through: Admin Panel -> Add dataset. You should then be able to follow the
introduction to the app (available from the landing page).8. After completing the instruction, you then will be able to access the user
interface ("Home") to annotate your own time series.### Docker
To use AnnotateChange locally using Docker, follow the steps below. For a
full-fledged installation on a server, see the [deployment
instructions](./docs/DEPLOYMENT.md).0. Install [docker](https://docs.docker.com/get-docker/) and
[docker-compose](https://docs.docker.com/compose/install/).1. Clone this repository and switch to it:
```
$ git clone https://github.com/alan-turing-institute/AnnotateChange
$ cd AnnotateChange
```2. Build the docker image:
```
$ docker build -t gjjvdburg/annotatechange .
```3. Create the directory for persistent MySQL database storage:
```
$ mkdir -p persist/{instance,mysql}
$ sudo chown :1024 persist/instance
$ chmod 775 persist/instance
$ chmod g+s persist/instance
```4. Copy the environment variables file:
```
$ cp .env.example .env
```
Some environment variables can be adjusted if needed. For example,
when moving to production, you'll need to change the `FLASK_ENV` variable
accordingly. Please also make sure to set a proper `SECRET_KEY` and
`AC_MYSQL_PASSWORD` (`= MYSQL_PASSWORD`). You'll also need to configure a
mail account so the application can send out emails for registration etc.
This is what the variables prefixed with ``MAIL_`` are for. The
``ADMIN_EMAIL`` is likely your own email, it is used when the app
encounters an error and to send backups of the annotation records. You can
limit the email domains users can use with the ``USER_EMAIL_DOMAINS``
variable. See the [config.py](config.py) file for more info on the
configuration options.5. Create a local docker network for communiation between the AnnotateChange
app and the MySQL server:
```
$ docker network create web
```6. Launch the services with docker-compose
```
$ docker-compose up
```
You may need to wait 2 minutes here before the database is initialized.
If all goes well, you should be able to point your browser to
``localhost:7831`` and see the landing page of the application. Stop the
service before continuing to the next step (by pressing `Ctrl+C`).7. Once you have the app running, you'll want to create an admin account so
you can upload datasets, manage tasks and users, and download annotation
results. This can be done using the following command:
```
$ docker-compose run --entrypoint 'flask admin add --auto-confirm-email' annotatechange
```8. As admin, upload **ALL** demo datasets (included in [demo_data](./demo_data))
through: Admin Panel -> Add dataset. You should then be able to follow the
introduction to the app (available from the landing page).9. After completing the instruction, you then will be able to access the user
interface ("Home") to annotate your own time series.## Notes

This code was written by [Gertjan van den Burg](https://gertjan.dev) with
helpful comments provided by [Chris
Williams](https://homepages.inf.ed.ac.uk/ckiw/).## Some implementation details
Below are some thoughts that may help make sense of the codebase.
* AnnotateChange is a web application build on the Flask framework. See [this
excellent
tutorial](https://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-i-hello-world)
for an introduction to Flask. The [flask.sh](./flask.sh) shell script loads
the appropriate environment variables and runs the application.* The application handles user management and is centered around the idea of a
"task" which links a particular user to a particular time series to
annotate.* An admin role is available, and the admin user can manually assign and
delete tasks as well as add/delete users, datasets, etc. The admin user is
created using the [cli](./app/cli.py) (see the Getting Started documentation
above).* All datasets must adhere to a specific dataset schema (see
[utils/dataset_schema.json](app/utils/dataset_schema.json)). See the files
in [demo_data] for examples, as well as those in
[TCPD](https://github.com/alan-turing-institute/TCPD).* Annotations are stored in the database using 0-based indexing. Tasks are
assigned on the fly when a user requests a time series to annotate (see
[utils/tasks.py](app/utils/tasks.py)).* Users can only begin annotating when they have successfully passed the
introduction.* Configuration of the app is done through environment variables, see the
[.env.example](.env.example) file for an example.* Docker is used for deployment (see the deployment documentation in
[docs](docs)), and [Traefik](https://containo.us/traefik/) is used for SSL,
etc.* The time series graph is plotted using [d3.js](https://d3js.org/).
