摘要

本文提出了一个预测模型管理系统DeVisa，该系统提供在线评分、模型组成、模型比较、搜索和统计等服务。为了在使用者应用程序和DeVisa系统之间进行交互，定义了一种称为PMQL的基于xml的语言。本文重点研究了作为在线知识提供者的计分服务，分析了实现这一目标所面临的挑战以及找到的解决方案。从技术角度来看，DeVisa使用原生XML数据库系统来存储用PMML表示的预测模型，并使用XQuery库来处理这些模型。所有的功能都是通过Web服务提供的。

Knowledge as a Service. An Online Scoring Engine Architecture

The paper presents a predictive models management system called DeVisa that offers online services such as: scoring, model composition, model comparison, search and statistics. For the purpose of interaction between the consumer applications and the DeVisa system a XML-based language called PMQL is defined. The paper focuses on the scoring service as an online knowledge provider, analyzes the challenges in achieving this objective and the solutions that were found. From a technological perspective DeVisa uses a native XML database system for storing the predictive models expressed in PMML and an XQuery library for processing the models. All the functionality is provided via Web Services.
