There’s a bit of a problem. The Soundex in Oracle only works for words in the English language. For other languages, you need a variation of the algorithm. The Dutch Russell Soundex is defined like this.

Soundex is a phonetic algorithm for indexing names by sound, as pronounced in English. The goal is for homophones to be encoded to the same representation so that they can be matched despite minor differences in spelling.[1] The algorithm mainly encodes consonants; a vowel will not be encoded unless it is the first letter. Soundex is the most widely known of all phonetic algorithms, as it is a standard feature of MS SQL and Oracle, and is often used (incorrectly) as a synonym for "phonetic algorithm". Improvements to Soundex are the basis for many modern phonetic algorithms....

Welcome to The Pac-Man Dossier! This web page is dedicated to providing Pac-Man players of all skill levels with the most complete and detailed study of the game possible. New discoveries found during the research for this page in December 2008 have allowed for the clearest view yet of the actual ghost behavior and pathfinding logic used by the game. Laid out in hyperlinked chapters and sections, the dossier is easy to navigate using the Table of Contents below, or you can read it in linear fashion from top-to-bottom. Chapter 1 is purely the backstory of Namco and Pac-Man's designer, Toru Iwatani, chronicling the development cycle and release of the arcade classic. If you want to get right to the technical portions of the document, however, feel free to skip ahead to Chapter 2 and start reading there. Chapter 3 and Chapter 4 are dedicated to explaining pathfinding logic and discussions of unique ghost behavior. Chapter 5 is dedicated to the “split screen” level, and several Appendices...

Weka is a collection of machine learning algorithms for data mining tasks. The algorithms can either be applied directly to a dataset or called from your own Java code. Weka contains tools for data pre-processing, classification, regression, clustering, association rules, and visualization. It is also well-suited for developing new machine learning schemes. Weka is open source software issued under the GNU General Public License....

It has been half a century since the computer burst upon the world along with promises that it would soon be programmed to be intelligent, and the related promise or threat that we would soon learn to understand ourselves as computers. In 1947 Alan Turing predicted that there would be intelligent computers by the end of the century. Now with the millennium only three years away, it is time for a retrospective evaluation of the attempt to program computers to be intelligent like HAL in the movie 2001....

In a nutshell, Wolfram and his team have built what he calls a "computational knowledge engine" for the Web. OK, so what does that really mean? Basically it means that you can ask it factual questions and it computes answers for you.
