Polyglot Machine Learning example for scraping similar news articles

In this example, we will see how we can work with Machine Learning applications written in Python with a NodeJS Script, to build a Polyglot Machine Learning application for scraping similar news articles.

Install

Install MetaCall CLI:

$ curl -sL https://raw.githubusercontent.com/metacall/install/master/install.sh | sh

Install application dependencies:

• For Python: metacall pip3 install -r requirements.txt
• For NodeJS: metacall npm i readline-sync

Run the Example

$ metacall app.js

Once the application is kick-started, you will be prompted to enter a News Article which you would like to find similar articles for. Let's use this sample article for testing our application: https://www.nytimes.com/2021/03/23/business/teslas-autopilot-safety-investigations.html

Here is the application output:

$ metacall app.js
Information: Global configuration loaded from /gnu/store/5cxmq6y8z24ijnvhh6lndgpriwnhf3jl-metacall-0.3.17/configurations/global.json
Enter the News URL:

Script (app.js) loaded correctly

Deployment using MetaCall FaaS

After deploying the application into the FaaS https://dashboard.metacall.io, it can be accessed with (change <your_alias> by the alias you used to sign up):

curl -X POST https://api.metacall.io/<your_alias>/ml-news-article-scraper-example/v1/call/similarNews -X POST --data '{ "url": "https://www.nytimes.com/2021/03/23/business/teslas-autopilot-safety-investigations.html" }'
