IBM OpenDX, the successor to IBM Visualization Data Explorer, (known simply as DX) is a general-purpose software package for data visualization and analysis. It employs a data-flow driven client-server execution model and provides a graphical program editor that allows the user to create a visualization using a point and click interface. Applications can also be built on top of portions of the Data Explorer system, so that custom, turnkey applications can be easily developed using DX as the computational and rendering engine.
NLTK, the Natural Language Toolkit, is a suite of Python libraries and programs for symbolic and statistical natural language processing. NLTK includes graphical demonstrations and sample data. It is accompanied by extensive documentation, including tutorials that explain the underlying concepts behind the language processing tasks supported by the toolkit.
The Aglets Software Development Kit (ASDK) is a framework and environment for developing and running mobile agents. Mobile Agents are a type of software agent that have the unique ability to transport themselves from one system to another. Doing so, an agent can start its execution on one host in a network, and then, while still executing, migrate to another host. The Aglets Software Development Kit (ASDK) comes with a complete server, called Tahiti, that hosts the running agents, a comlete library for building mobile agents and a set of prebuilt examples along with the documentation.
