About
I'm Chris Lowis - welcome to my home on the web! I'm a research engineer at BBC Research and Development with an interest in acoustics, Ruby programming, natural language processing, statistics and working with and automatically creating metadata.
I also like to bake bread, write code, play guitar, drink real ale, work wood, and watch football

Github Projects
My open-source code and projects are on github in my personal account, or as part of the BBC R&D organisation. A few examples:
- RadioDNS Ruby is a library for working with the Hybrid Radio technology RadioDNS.
- Similarity calculates the similarity between two pieces of text using TF-IDF weights.
- Source Classifier uses a Bayesian classifier to identify programming languages
- Data visualisation in Ruby contains lots of examples of generating charts and graphs using Ruby.
- My port of Peter Norvig's lisp to Ruby.
