Predictive Model Markup Language
Predictive Model Markup Language ( PMML ) is an XML- based standard that has been continuously developed since 1997 for the exchange of results between different programs for data mining . In most cases, the respective program (prudsys Expert Mining Suite, IBM Intelligent Miner, TIBCO Spotfire Miner , KXEN, SAS Enterprise Miner, SPSS Clementine, KNIME ) offers an export function for the created evaluation results in PMML format. The result, encoded in this way, should be able to be imported into systems from other manufacturers, which should make the updating and exchange of created classifiers , decision trees, etc. between companies much easier and faster. Some manufacturers who support the PMML standard have joined forces in the Data Mining Group (DMG) in order to continue working together on the standard.
PMML is a dialect of XML. The advantage is a simple integration into your own system and the readability and interpretability by people.
