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.
Multi-Dimensional Clustering (MDC) Table Size Estimator for DB2 is an application that can be used to optimally estimate space requirements based on table statistics and MDC parameters. It has the ability to use one or more clustering dimensions, which speeds up the query process and frees users from the burdens of converting a table to MDC on AIX and Windows.
Visual Performance Analyzer (VPA) is an Eclipse-based performance visualization toolkit, similar to Intel's VTune and AMD's CodeAnalyst. It is for the Linux, Java, and Windows platforms. It uses three major components that work to narrow down performance problems, show statistics, and examine code execution on IBM POWER processors.
