Pretzel.SimilarPosts

Allows you find similar posts for your blog and add It's may be interested for you links to your blog pages.

This is a plugin for the static site generation tool Pretzel.

Usage

To use this plugin you have to add configuration to _config.yml. Typical configuration could be like this:

similar_posts:
    filter_threshold: 0.3
    related_count: 3
    weight:
        categories: 0.1
        tags: 0.3
        title: 0.2
        text: 1
    stemmers:
      - English
      - Russian
    reserved:
      - asp.net
      - .net
      - vs.net

Configuration parameters are:

• filter_threshold is param to define threshold for posts, it could be number from 0 to 1.
• related_count is param to define related posts count for each page.
• weight is param to determine weight of different factors in comparision process. It accepts numbers from 0 to 1. In this version the plugin is able to compare by category, tag, title and text (blog post content).
• stemmers is param to define which stemmers to use to pre-process the text. The plugin uses StemmersNet library for that. If you're using another language feel free to add additional languages availeable at StemmersNet.
• reserved is param to define reserver words whcih won't be processed. During the comparision process all non-alphanumeric symbols will be removed. It's fine for most cases. But it's wrong for some situations like asp.net word. If we won't add it to reserved list the plugin will understand it as two different words asp and net, which is wrong. So we add it to reserved list and plugin won't pre-process it at all.

Once we configure the plugin in _config.yml there will be available page.related variable for each page. To use it add code like this into your post.html file:

{% if page.related.size > 0 -%}
<section class="related">
    <h4>You may be interested in</h4>
    <ul>
        {% for page in page.related -%}
        <li><a href="/{{page.url}}">{{page.title}}</a></li>
        {% endfor -%}
    </ul>
</section>
{% endif -%}
