The "Virtual Universe" is a realistic, three-dimensional cyberspace and virtual reality simulation. People can meet, interact with each other, build houses and whole worlds, simulate workflows, test designs, and much more. Due to its extensive programming interface, this virtual reality environment can be used for scientific and engineering tasks such as simulation and visualization applications. It also includes a terrain generator for virtual landscapes and the Java XTools, an extensive package that contains several enhancements and improvements for Java3D and Swing.
pyECTOR is a chatterbot which learns from what people say. It is based on an artificial intelligence architecture that is inspired by Copycat, an AI system from Mitchell and Hofstadter. The Concept Network it uses is a mix between neural and semantic networks. It uses co-occurrences to compute the influence of one semantic node on another. The links are statistically weighted.
