Metaforecast late 2022 update: GraphQL API, Charts, better infrastructure behind the scenes.
|
|||
|
|
==============
|
|||
|
|
|
|||
|
|
**tl;dr**: [Metaforecast](https://metaforecast.org/) is a search engine and an associated repository for forecasting questions. Since our [last update](https://metaforecast.substack.com/p/metaforecast-update-better-search), we have added a GraphQL API, charts, and dashboards. We have also reworked our infrastructure to make it more stable.
|
|||
|
|
|
|||
|
|
## New API
|
|||
|
|
|
|||
|
|
Our most significant new addition is our GraphQL API. It allows other people to build on top of our efforts. It can be accessed on [metaforecast.org/api/graphql](https://metaforecast.org/api/graphql), and looks similar to the EA Forum's [own graphql api](https://forum.effectivealtruism.org/graphiql).<p><img src='https://i.imgur.com/xHRBMNb.png' class='.img-medium-center'></p>
|
|||
|
|
|
|||
|
|
To get the first 1000 questions, you could use a query like:
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
{
|
|||
|
|
questions(first: 1000) {
|
|||
|
|
edges {
|
|||
|
|
node {
|
|||
|
|

|
|||
|
|

|

|
|||

|
|||
|
|

|
|||
|
|
}
|
|||
|
|

|
|||
|
|
}
|
|||
|
|
}
|
|||
|
|
pageInfo {
|
|||
|
|
endCursor
|
|||
|
|
startCursor
|
|||
|
|
}
|
|||
|
|
}
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
You can find more examples, like code to download all questions, in our [/scripts](https://github.com/quantified-uncertainty/metaforecast/tree/master/scripts) folder, to which we welcome contributions.
|
|||
|

|
|||
|
|
## Charts and question pages.
|
|||
|
|
|
|||
|
|
Charts display a question's history. They look as follows:
|
|||
|
|
|
|||
|
|

|
|||
|
|
|
|||
|
|
Charts can be accessed by clicking the expand button on the front page although they are fairly slow to load at the moment.
|
|||
|
|
|
|||
|
|
<img src='https://i.imgur.com/JJCrUjn.png' class='.img-medium-center'>
|
|||
|
|
|
|||
|
|
Clicking on the expand button brings the user to a question page, which contains a chart, the full question description, and a range of quality indicators:
|
|||

|||

|

|
|||
|
|
|
|||
|
|
We are also providing an endpoint at _metaforecast.org/questions/embed/\[id\]_ to allow other pages to embed our charts. For instance, to embed a question whose id is _betfair-1.178163916_, the endpoint would be [here](https://metaforecast.org/questions/embed/betfair-1.178163916). One would use it in the following code:
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
<iframe
|
|||
|
|
src="https://metaforecast.org/questions/embed/betfair-1.178163916"
|
|||
|
|
height="200"
|
|||
|
|
width="300"
|
|||
|
|
title="Metaforecast question"
|
|||
|
|
></iframe>
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
You can find the necessary question id by clicking a toggle under "advanced options" on the frontpage, or simply by noticing the id in our URL when expanding the question.
|
|||
|
|
|
|||
|
|
With time, we aim to improve these pages, make them more interactive, etc. We also think it would be a good idea to embed Metaforecast questions and dashboards into the EA Forum, and we are trying to collaborate with the [Manifold team](https://github.com/ForumMagnum/ForumMagnum/pull/6015), who have [done this before](https://github.com/ForumMagnum/ForumMagnum/pull/4907), to make that happen.
|
|||
|
|
|
|||
|
|
## Dashboards
|
|||
|
|
|
|||
|
|
Dashboards are collections of questions. For instance, [here](https://metaforecast.org/dashboards/view/561472e0d2?numCols=2) is a dashboard on global markets and inflation, as embedded in [Global Guessing](https://globalguessing.com/russia-ukraine-forecasts/).
|
|||
|
|
|
|||
|
|

|
|||
|
|
|
|||
|
|
Like questions, you can either [view dashboards directly](http://metaforecast.org/dashboards/view/561472e0d2?numCols=2), or [embed](http://metaforecast.org/dashboards/embed/561472e0d2?numCols=2) them. You can also create them, at [https://metaforecast.org/dashboards](https://metaforecast.org/dashboards).
|
|||
|
|
|
|||
|
|
## Better infrastructure
|
|||
|
|
|
|||
|
|
We have also revamped our infrastructure. We moved to from JavaScript to Typescript, from MongoDB to Postgres, and simplified our backend.
|
|||
|
|
|
|||
|
|
## We are open to collaborations
|
|||
|
|
|
|||
|
|
We are very much open to collaborations. If you want to integrate Metaforecast into your project and need help do not hesitate to reach out, e.g., on our [Github](https://github.com/quantified-uncertainty/metaforecast/issues).
|
|||
|
|
|
|||
|
|
Metaforecast is also open source, and we welcome contributions. You can see some to-dos [here](https://github.com/quantified-uncertainty/metaforecast#to-do). Developing is going more slowly now because it's mostly driven by Nuño working in his spare time, so contributions would be counterfactual.
