DALLAS & HOUSTON--(BUSINESS WIRE)--April 26, 2005--PolyVista, Inc. today announces that Southwest Airlines Co. (NYSE:LUV) has implemented and deployed PolyVista's Discovery solution to enhance the analysis capability of its existing pilot reporting program data through the addition of PolyVista's text and data-mining analysis solution.

"We immediately moved forward with PolyVista, and their solution was implemented in just three weeks! PolyVista brings together both our structured (numeric) data and our unstructured (textual) data from our incident reports. It provides an easy-to-use environment that enables our staff to not only 'ask a question and get an answer' but also automatically guides our users to new and unexpected information hidden in our data. The automated Discovery function of PolyVista increases our analysis capabilities without having to add additional staff. It's like adding really smart and experienced analysts," Tim said.

"SWA uses PolyVista's Discovery data and text mining software to assist our safety department employees in identification of operational issues and the development of mitigation factors aimed at prevention. PolyVista's Discovery assists SWA in the identification of causal factors from the reports submitted by our pilots. SWA sees the addition of this capability as a key part of our safety program that enables us to more efficiently analyze our safety information," Tim stated.
