Web Site Optimisation
Petrželka, Jiří ; Burget, Radek (oponent) ; Eysselt, Miloš (vedoucí práce)
This BSc Project was performed during a study stay at the Coventry University, UK. The goal of this project is to enhance the accessibility and usability of an existing company presentation located at http://www.hcc.cz, boost the site's traffic and so increase the company's revenues. The project follows these steps to accomplish this: a ) A partial refactoring of the back-end (PHP scripts). b ) Transformation of the website contents according to the recommendations of the World Wide Web consortium (W3C) and in particular to those of the Web Accessibility Initiative (WAI). c ) Application of the Search Engine Optimization (SEO) techniques and analysis of their impact. In this step, the project touches upon the Search Engine Marketing (SEM).

Czech-English Translation
Petrželka, Jiří ; Schmidt, Marek (oponent) ; Smrž, Pavel (vedoucí práce)
This Master's thesis describes the principles of statistical machine translation and demonstrates how to assemble the Moses statistical machine translation system. In the preparation step, a research on freely available bilingual Czech-English corpora is done. An empirical analysis of time requirements of multithreaded word alignment tools demonstrates that MGIZA++ can achieve a five-fold speed-up, while PGIZA++ can reach an eight-fold speed-up (compared to GIZA++).Three scenarios of morphological pre-processing of Czech training data are tested, using simple unfactored models. While pure lemmatization can aggravate the BLEU, more sophisticated approaches usually raise BLEU. The positive effect of morphological pre-processing diminishes as corpus size rises. The relation between other corpora characteristics (size, genre, extra data) and the resulting BLEU are empirically gauged. A final system is trained on the CzEng 0.9 corpus and evaluated on the testing set from WMT 2010 workshop.
