CPSBayes is a naive bayesian classifier, that uses the same kind of algorithms than software like SpamAssassin. Its main use case is to categorize incoming mails in CPSCourier, a complete solution for mail and notes managment.

The tool stores data in the ZODB or in any kind of SQL Database, using SQLObject connector.

Categorization can apply to a lot of other use cases as well, and I have coded a small product called CPSBayesExample that shows how simple it is to set and use CPSBayes over a portal.

The product provides a textarea where you can type some text, and show some pictures and categories that are guessed by CPSBayes, with the text. The page is dynamically updated through Ajax, with a simple keystroke.

The categories can be trained as well so you can make it learn new patterns.

This simple demo shows how CPSBayes could be used to do automatic metadata filling with a very few lines of code.

To get it, checkout the code from our subversion:

  # svn co https://svn.nuxeo.org/pub/CPS3/examples/CPSBayesExample/trunk CPSBayesExample

Like Julien has started to announce, we are going to be present at Europython this year, and I am really excited to be part of it.

I will present three topics:

• CPSBayes: a bayesian classifier of Zope ( abstract)
• Ajax, state of the art: a presentation about Ajax, Javascript, that will mainly focus on agile development techniques with javascript, and how it can be integrated in a Zope project continuous integration. ( abstract)
• zope-cookbook.org: a presentation on a personal project I am doing to create a cookbook for Zope 3. The talk focuses on the project agility obtained through doctests and efficient writing techniques. This is quite important to document code bases that still moves a lot like Zope 3 ( abstract)

Julien's talk will be very interesting to follow as well (trust me, NXLucene really rocks).

July will be Python fest, since right after EP, the AFPY user group will be part of the Libre Software Meeting in Nancy (FRA) to cover Python in a local meeting that will be juicy as well.
