摘　　要：近年来,现代信息技术和智能技术与教育教学的融合逐步深入,SMART教育、MOOC(massive open online courses)教育、STEAM教育、教育分析技术相继涌现。在教育领域,人们开始尝试建立学习者的数字画像(learner’s digital portraits,LDP),通过对学习者及其背景的相关数据的测量、收集和分析,了解和优化学习者的自我学习和学习环境,推动学习者个性化教育的开展和深化,帮助教育工作者对学习者实现“因材施教”。学习者数字画像构建是一个复杂的过程,需要考虑不同的用户需求和不同的具体应用,从多个不同的数据源抽取主题数据,并做相应的结构化处理,然后用解析引擎进行可视化解析。针对学习者数字画像的构建过程,提出一种基于可扩展标记语言(extensible markup language,XML)的开放式学习者数字画像构建设计,从技术层面探讨开放式立体化的学习者数字画像实现。Now,alone with the gradually deepening integration of modern IT technologies and intelligent technologies with education,the SMART education,MOOC education,STEAM education and educational analytics technologies has been emerged and fast developed.In educational area,researchers has been started to build learner’s digital portraits(LDP)which is based on learners study and environments data.By collection and analysis of these data to help better understanding and optimization learners’self-learning and learning environments,and the individualized education can be really performed in practice.The learners’digital portraits(LDP)construction procedure is a complex issue,it needs to take care about different users with different applications and extract different subject data from different data sources,and then by format processing of these subject data with engine to build the visualization image.Here,based on learners’digital portraits(LDP)constriction,an XML based opening learners’digital portraits(LDP)construction solution is illustrated and its implementation is discussed from technical point of view.
