Alice is an innovative 3D programming environment that makes it easy to create an animation for telling a story, playing an interactive game, or a video to share on the web. Alice is a teaching tool for introductory computing. It uses 3D graphics and a drag-and-drop interface to facilitate a more engaging, less frustrating first programming experience.

Carneades is an argument mapping application, with a graphical user interface, and a software library for building applications supporting various argumentation tasks.

World Wind lets you zoom from satellite altitude into any place on Earth. Leveraging Landsat satellite imagery and Shuttle Radar Topography Mission data, World Wind lets you experience Earth terrain in visually rich 3D, just as if you were really there.

The Lemur Toolkit is a open-source toolkit designed to facilitate research in language modeling and information retrieval. Lemur supports a wide range of industrial and research language applications such as ad-hoc retrieval, site-search, and text mining. The toolkit supports indexing of large-scale text databases, the construction of simple language models for documents, queries, or subcollections, and the implementation of retrieval systems based on language models as well as a variety of other retrieval models. The system is written in the C and C++ languages, and is designed as a research system to run under Unix operating systems, although it can also run under Windows.

Argument maps are diagrams that display the structure of an argument. By combining pictures and words, argument maps help people to create better arguments and analyses. iLogos is a freely-available, cross-platform tool that allows you to easily construct and share argument maps.

The Network Workbench Community Wiki is the part of Network Workbench (NWB) project. It provides descriptions for algorithms and datasets that have been integrated in the NWB Tool. It is also a place for users of the NWB Tool, the Cyberinfrastructure Shell, or any other CIShell based program to get, upload, and request algorithms & datasets to be used in the tool. This site is a sounding board to be used by the community to work together and create a tool which will meet their needs and the needs of the scientific community at large.

OpenEphyra is an open framework for question answering (QA). It retrieves answers to natural language questions from the Web and other sources. Visit http://www.ephyra.info/ for more details and information on joining this open research initiative.

Araucaria is a software tool for analysing arguments. It aids a user in reconstructing and diagramming an argument using a simple point-and-click interface.

Belvedere 4.1 is designed to help support problem-based collaborative learning scenarios with concept and evidence moodels, and provides multiple representational views (tables and graphs) on those models. Belvedere was originally intended to help secondary school students learn critical inquiry skills that they can apply in everyday life as well as in science, but can be adopted to other applications as well.
