Welcome to my home page!
I am a computer scientist and an author. Currently, I'm working as a freelance software engineer and text mining expert in Berlin, Germany. I hold a Ph.D. in computer science from the Freie Universität Berlin.
What You'll Find on My SiteFree SoftwareI have contributed to various free software projects, and have also written a few (mostly small) programs of my own. On this page you can also find a list of my translations for the GNU Project and an overview of my experiences in commercial software development. Free SocietyI'm involved in a blog and wiki discussing whether and how the practices of free software and open content development can be extended to other areas of production, and whether an economy based on this mode of production is possible. Additionally, this page links texts related to study reform and democracy which I wrote as a student, and more. Spam FilteringSpam is ubiquitous, highly adapting to any counter-measures, and most annoying. This makes spam filtering one of the most important and interesting research topics in the field of text classification and text mining. Here you'll find my contributions to this effort. Information ExtractionThis page is dedicated to my Ph.D. project. The primary goal of my Ph.D. research was to develop and evaluate a statistical system for the extraction of information from natural language texts that supports incremental training and that takes the structure of texts into account. My Ph.D. thesis, publications, and software are all available here. History of ComputingAs a student I worked for an experimental teaching project with the purpose of giving computer science students a better insight into how to write good papers and to conduct larger research activities. As the topic area of the project we had chosen historical developments in the fields of computer science and software development; both to open up an interesting field of exploration that is largely outside the scope of usual CS teachings and to provide the students with a better understanding of the history of their own field.

Keimform ArticlesI'm a co-author in the German-language Keimform-Blog, a group weblog discussing whether and in which ways commons-based peer production has a potential that extends beyond the areas of free software and open content production where it has first emerged. Here you can preview my most recent contributions and the latest articles published in the blog by any author.
