Robert M. Losee: Indexing and Metadata Advantage (IMA) Validation Software:

• IMA Validation software that determines whether the models suggested in The Effect of Assigning a Metadata or Indexing Term on Document Ordering, (Journal of the American Society for Information Science and Technology. 2013, In Press.) are accurate for all document sets up to size n where the assumptions of the model are met.

• Runs on almost any unix or linux system. You may need to install "gawk" (gnu awk) if it isn't already installed (it is in most unix or linux software libraries and is easily installed in a minute on most linux systems)
• The software contains no "system" commands (e.g. system("date")) that could execute possibly dangerous operations, and the author is aware of no ways that the IMA software should be able to damage your system other than to slow it down. IMA is CPU intensive software!
