“…A range of software tools are available today that help in carrying out data mining software projects (Britos et al, 2005;Kdnuggets, 2005;MetaGroup, 2004). Based on the list of such tools that appear in MetaGroup (MetaGroup, 2004) and Kdnuggets (Kdnuggets, 2005), an evaluation was made of the most representative, including: Clementine (Khabaza & Shearer, 1995;SPSS-Inc., 2009), Insightful Miner (Insightful-Corporation), WEKA (Holmes, Donkin, & Witten, 1994;University-of-Waikato, 2009), CART (Salford-System, 2009), PolyAnalyst (Mai, Krishna, & Reddy, 2005;Megaputer, 2009;Rippa & Lendyuk, 2007) and SAS Enterprise Miner (SAS, 2009a). The general criteria for such evaluation were: its access (cost of the tools), its user interface (how easy or complex the tool was to use according to the user), the process (or methodology) on which it was based, its extensibility (the capacity to easily and dynamically expand the set of algorithms it offers) and support in project development for individuals to work together in groups.…”
