Abstract:
In this paper we describe DeVisa, a Web system for scoring and management of data mining models. The system has been designed to provide unified access to different prediction models using standard technologies based on XML. The prediction models are serialized in PMML format and managed using a native XML database system. The system provides functions such as scoring, model comparison, model selection or sequencing through a web service interface. DeVisa also defines a specialized PMML query language named PMQL used for specifying client requests and interaction with PMML repository. The paper analyzes the system’s architecture and functionality and discusses its use as a tool for researchers.
