-title: Hate Speech Dataset Catalogue
----
-
-This page catalogues datasets annotated for hate speech, online abuse, and offensive language. They may be useful for e.g. training a natural language processing system to detect this language.
-
-The list is maintained by Leon Derczynski, Bertie Vidgen, Hannah Rose Kirk, Pica Johansson, Yi-Ling Chung, Mads Guldborg Kjeldgaard Kongsbak, Laila Sprejer, and Philine Zeinert.
-
-We provide a list of datasets and keywords. If you would like to contribute to our catalogue or add your dataset, please see the instructions for contributing.
-
-If you use these resources, please cite (and read!) our paper: Directions in Abusive Language Training Data: Garbage In, Garbage Out. And if you would like to find other resources for researching online hate, visit The Alan Turing Institute’s Online Hate Research Hub or read The Alan Turing Institute’s Reading List on Online Hate and Abuse Research.
-
-If you’re looking for a good paper on online hate training datasets (beyond our paper, of course!) then have a look at ‘Resources and benchmark corpora for hate speech detection: a systematic review’ by Poletto et al. in Language Resources and Evaluation.
-
-## How to contribute
-
-We accept entries to our catalogue based on pull requests to the content folder. The dataset must be avaliable for download to be included in the list. If you want to add an entry, follow these steps!
-
-Please send just one dataset addition/edit at a time - edit it in, then save. This will make everyone’s life easier (including yours!)
-
-- Go to the repo url file and click the "Add file" dropdown and then click on "Create new file".
-![](https://i.imgur.com/2PR0ZgL.png)
-   
-- In the following page type `content/datasets/<name-of-the-file>.md`. if you want to add an entry to the datasets catalog or `content/keywords/<name-of-the-file>.md` if you want to add an entry to the lists of abusive keywords, if you want to just add an static page you can leave in the root of `content` it will automatically get assigned an url eg: `/content/about.md` becomes the `/about` page
-![](https://i.imgur.com/rr3uSYu.png)
-   
-- Copy the contents of `templates/dataset.md` or `templates/keywords.md` respectively to the camp below, filling out the fields with the correct data format
-![](https://i.imgur.com/x6JIjhz.png)
-   
-- Click on "Commit changes", on the popup make sure you give some brief detail on the proposed change.  and then click on Propose changes
-<img src='https://i.imgur.com/BxuxKEJ.png' style={{ maxWidth: '50%', margin: '0 auto' }}/>
-   
-- Submit the pull request on the next page when prompted.

+This is a replica of the awesome data.fivethirtyeight.com using PortalJS.
+
+You might be asking why we did that, there are three main reasons:
+
+- The website has a great UI, with multiple datasets being displayed elegantly and with simplicity.
+- PortalJS allows us to add more functionality to it e.g dataset previews and search functionality.
+- The project follows our same principles of open sourcing and free data, with every dataset being publicly available on Github.
+
+## Getting Started
+
+First, run the development server:
+
+```bash
+npm run dev
+# or
+yarn dev
+# or
+pnpm dev
+```
+
+Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+
+You can start editing the page by modifying `pages/index.tsx`. The page auto-updates as you edit the file.
+
+[API routes](https://nextjs.org/docs/api-routes/introduction) can be accessed on [http://localhost:3000/api/hello](http://localhost:3000/api/hello). This endpoint can be edited in `pages/api/hello.ts`.
+
+The `pages/api` directory is mapped to `/api/*`. Files in this directory are treated as [API routes](https://nextjs.org/docs/api-routes/introduction) instead of React pages.
+
+This project uses [`next/font`](https://nextjs.org/docs/basic-features/font-optimization) to automatically optimize and load Inter, a custom Google Font.
+
+## Learn More
+
+To learn more about Next.js, take a look at the following resources:
+
+- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
+- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
+
+You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js/) - your feedback and contributions are welcome!
+
+## Deploy on Vercel
+
+The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.
+
+Check out our [Next.js deployment documentation](https://nextjs.org/docs/deployment) for more details.

+# A data catalog with data on GitHub
+
+This example showcases a simple data catalog that get its data from a list of GitHub repos that serve as datasets.
+
+A `datasets.json` file is used to specify which datasets are going to be part of the data catalog.
+
+The application contains an index page, which lists all the datasets specified in the `datasets.json` file, and users can see more information about each dataset, such as the list of data files in it and the README, by clicking the "info" button on the list.
+
+You can read more about it on the [Data catalog with data on GitHub](https://portaljs.org/docs/examples/github-backed-catalog) blog post.
+
+## Demo
+
+https://example.portaljs.org/
+
+## Deploy your own
+
+[![Deploy with Vercel](https://vercel.com/button)](https://vercel.com/new/clone?repository-url=https%3A%2F%2Fgithub.com%2Fdatopian%2Fportaljs%2Ftree%2Fmain%2Fexamples%2Fgithub-backed-catalog)
+
+By clicking on this button, you will be redirected to a page which will allow you to clone the content into your own GitHub/GitLab/Bitbucket account and automatically deploy everything.
+
+## How to use
+
+### Install
+
+Execute `create-next-app` to bootstrap the example:
+
+```
+npx create-next-app <app-name> --example https://github.com/datopian/portaljs/tree/main/examples/github-backed-catalog
+cd <app-name>
+```
+
+### Set environment variables
+
+This project uses the GitHub API, which for anonymous users will cap at 50 requests per hour, so you might want to get a [Personal Access Token](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/creating-a-personal-access-token) and add it to a `.env` file inside the folder like so
+
+```
+GITHUB_PAT=<github token>
+```
+
+### Change datasets
+
+You can change the datasets that will be displayed in the data catalog by editing the file `datasets.json`. Some examples can be found inside [this repo](https://github.com/datasets).
+
+### Run in development mode
+
+Run the app using:
+
+```
+npm run dev
+```
+
+Open http://localhost:3000 from your browser. You should see something similar to this:
+
+![](https://i.imgur.com/jAljJ9C.png)
+
+If click on the `info` button for a dataset you will see a page similar to this:
+
+![](https://i.imgur.com/AoJd4O0.png)
+
+## Notes
+
+### Structure of `datasets.json`
+
+The `datasets.json` file is simply a list of datasets, below you can see a minimal example of a dataset:
+
+```json
+{
+  "owner": "fivethirtyeight",
+  "repo": "data",
+  "branch": "master",
+  "files": ["nba-raptor/historical_RAPTOR_by_player.csv", "nba-raptor/historical_RAPTOR_by_team.csv"],
+  "readme": "nba-raptor/README.md"
+}
+```
+
+It has:
+
+- A `owner` which is going to be the github repo owner
+- A `repo` which is going to be the github repo name
+- A `branch` which is going to be the branch to which we need to get the files and the readme
+- A list of `files` which is going to be a list of paths with files that you want to show to the world
+- A `readme` which is going to be the path to your data description, it can also be a subpath eg: `example/README.md`
+
+You can also add:
+
+- A `description` which is useful if you have more than one dataset for each repo, if not provided we are just going to use the repo description
+- A `Name` which is useful if you want to give your dataset a nice name, if not provided we are going to use the junction of the `owner` the `repo` + the path of the README, in the exaple above it will be `fivethirtyeight/data/nba-raptor`
+
+### Extra commands
+
+You can also build the project for production with:
+
+```
+npm run build
+```
+
+And run the production build with:
+
+```
+npm run start
+```

+# A data catalog with data on GitHub
+
+This example showcases a simple data catalog that get its data from a list of GitHub repos that serve as datasets.
+
+A `datasets.json` file is used to specify which datasets are going to be part of the data catalog.
+
+The application contains an index page, which lists all the datasets specified in the `datasets.json` file, and users can see more information about each dataset, such as the list of data files in it and the README, by clicking the "info" button on the list.
+
+You can read more about it on the [Data catalog with data on GitHub](https://portaljs.org/docs/examples/github-backed-catalog) blog post.
+
+## Demo
+
+https://example.portaljs.org/
+
+## Deploy your own
+
+[![Deploy with Vercel](https://vercel.com/button)](https://vercel.com/new/clone?repository-url=https%3A%2F%2Fgithub.com%2Fdatopian%2Fportaljs%2Ftree%2Fmain%2Fexamples%2Fgithub-backed-catalog)
+
+By clicking on this button, you will be redirected to a page which will allow you to clone the content into your own GitHub/GitLab/Bitbucket account and automatically deploy everything.
+
+## How to use
+
+### Install
+
+Execute `create-next-app` to bootstrap the example:
+
+```
+npx create-next-app <app-name> --example https://github.com/datopian/portaljs/tree/main/examples/github-backed-catalog
+cd <app-name>
+```
+
+### Set environment variables
+
+This project uses the GitHub API, which for anonymous users will cap at 50 requests per hour, so you might want to get a [Personal Access Token](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/creating-a-personal-access-token) and add it to a `.env` file inside the folder like so
+
+```
+GITHUB_PAT=<github token>
+```
+
+### Change datasets
+
+You can change the datasets that will be displayed in the data catalog by editing the file `datasets.json`. Some examples can be found inside [this repo](https://github.com/datasets).
+
+### Run in development mode
+
+Run the app using:
+
+```
+npm run dev
+```
+
+Open http://localhost:3000 from your browser. You should see something similar to this:
+
+![](https://i.imgur.com/jAljJ9C.png)
+
+If click on the `info` button for a dataset you will see a page similar to this:
+
+![](https://i.imgur.com/AoJd4O0.png)
+
+## Notes
+
+### Structure of `datasets.json`
+
+The `datasets.json` file is simply a list of datasets, below you can see a minimal example of a dataset:
+
+```json
+{
+  "owner": "fivethirtyeight",
+  "repo": "data",
+  "branch": "master",
+  "files": ["nba-raptor/historical_RAPTOR_by_player.csv", "nba-raptor/historical_RAPTOR_by_team.csv"],
+  "readme": "nba-raptor/README.md"
+}
+```
+
+It has:
+
+- A `owner` which is going to be the github repo owner
+- A `repo` which is going to be the github repo name
+- A `branch` which is going to be the branch to which we need to get the files and the readme
+- A list of `files` which is going to be a list of paths with files that you want to show to the world
+- A `readme` which is going to be the path to your data description, it can also be a subpath eg: `example/README.md`
+
+You can also add:
+
+- A `description` which is useful if you have more than one dataset for each repo, if not provided we are just going to use the repo description
+- A `Name` which is useful if you want to give your dataset a nice name, if not provided we are going to use the junction of the `owner` the `repo` + the path of the README, in the exaple above it will be `fivethirtyeight/data/nba-raptor`
+
+### Extra commands
+
+You can also build the project for production with:
+
+```
+npm run build
+```
+
+And run the production build with:
+
+```
+npm run start
+```
+
