We should provide a method on each blog article that returns "related articles" for that article. We can crib the algorithm for related posts from https://wordpress.org/extend/plugins/yet-another-related-posts-plugin/

I currently use this short method

  def related(page)
    all_pages = blog.tags.slice(*page.tags).values.first
    return [] if all_pages.blank?

    all_pages.delete_if { |p| p == page }
  end

  related(current_page)

It will return articles collection tied with current page by tags.

Would be a nice feature!

I haven't played around with this, but one solution could be to calculate the Levenshtein distance between the page content (yield) and each of the posts' content (page_articles.each). In other words, find out how different each of the article strings are from the current article.

The articles with the lowest Levenshtein distance are the related posts.

Here are two Ruby-based algorithm implementations:

@dconjar Looks interesting. We should definitely make the implementation pluggable though. Maybe allow other extensions to handle the details
