Resources to get you started with Algorithmia

Sentiment Analysis Pipeline


Available on GitHub.

While sometimes text content is easily retrieved through a database query, other times it’s not so simple to extract. For instance, it’s notoriously difficult to retrieve text content from websites, especially when you don’t want to extract everything from a URL — just the text content of specific pages.

For example, if you want to derive the sentiment from specific pages on a website, you can easily spend hours finding an appropriate web scraper, and then weeks labeling data and training a model for sentiment analysis.

This code snippet shows how to use Algorithmia to grab all the links from a web page, extracts the text content from each URL, and then returns the sentiment of each page.
