I am in the software development business since 1995 and fascinated about the nature of software, which (I think) is very very difficult to catch. Beside this I am interested in the area of ''web data mining'' and ''web information extraction''. ''Software "Engineering" is about managing unpredictability'' you can find my (partially outdated) homepage at http://www.dbai.tuwien.ac.at/user/pollak and my blog at http://www.nature-of-software.com
