a freely available commonsense knowledgebase and natural-language-processing toolkit which supports many practical textual-reasoning tasks over real-world documents right out-of-the-box (without additional statistical training)
a new similarity ranking algorithm, together with its associated string similarity metric. I also include Java source code, so you can easily incorporate the algorithm into your own applications.
page has visualizations of some comparison based sorting algorithms. The quick sort, bubble sort and cocktail shaker sort are due to the good folks at Sun Microsystems. The original SortItem applet was written by James Gosling.
a rule engine and scripting environment written entirely in Sun's Java, you can build Java software that has the capacity to "reason" using knowledge you supply in the form of declarative rules. Jess is small, light, and one of the fastest rule engines av
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.
