Post summarizer

Description

This plugin create an automatic excerpt of a post when it is saved or published. The excerpt created is a coherent piece of
text containing the most important sentences of the post.
After installing this plugin, every time you write a post and press the save or publish button an excpert is created for that
post and stored in the database. This plugin is useful also if you don’t use excerpts in your blog: it’s always useful
to have a summary of your post available just to remind yourself what the post is about (it works very well with old and long posts!).
Statistical natural language techniques are used to extract the most important sentences from a document. It’s straightforward to
tweak the plugin to give more importance to certain features in your text.
The code of the plugin has been optimized for extensiblity in order to make it easy for contributor developers to implement a summarizer
in their own language. At the moment only an English language summarizer is available, and an Italian one is on its way.

After activating the plugin here are simple steps that you might want to follow in order to have a nice excerpt to use in
your blog.

1. Write your post
2. Press the save or publish button
3. An excerpt will be created. Now you can review it, modify it and save it as many times as needed
4. If you want the summarizer to create an excerpt again delete the existing one and press save or publish

Note that the plugin creates automatically an excerpt for a post only if there isn’t already an excerpt for that post

How to adapt the plugin to summarize documents in other languages (for developers)

If you want to adapt the plugin to make it work with languages other than English you have to:

1. Create a directory named with a code for the language: e.g. ‘EN’, ‘IT’, ‘JP’ and so on.
2. Create a class that extend the abstract class Document in lib/
3. Implement the tokenize() and normalize() methods.
4. Add config information to che config.php file

It’s easier than it seems. The code for the English summarizer is well commented and explains what you need to know in order to
extend it. Don’t hesitate to contact me if you need more info or help. Enjoy!
