Content Cleansing

The goal of content cleansing is to ensure we pass the cleanest possible signal into our interest graph service. It is a multiple step process that involves:

  1. Article Crawling
  2. Heuristics based content extraction and weighting
  3. NLP weighted phrase extraction and POS tagging

You can check out the results of the content cleansing phase for your user's 10 articles below. To learn more, head over to our Goose Content Extractor Labs page
