面向用户需求的多源在线健康社区信息多层级融合框架研究

Research on Multi-level Information Fusion Framework of Multi-source Online Health Community Oriented User Needs

[目的/意义]有效实现多源异构在线健康信息资源的有机融合,是开展健康信息知识型服务的重要基础。[方法/过程]首先,根据信息生成方式提炼出在线医疗健康平台中健康信息的主要特征;其次,依据用户对医疗健康信息探索实践的目标、任务与过程,将用户在线健康信息需求进行层级划分;最后,建立用户健康信息需求的响应机制。[结果/结论]在此基础上,构建面向用户需求的多源在线健康社区信息多层级融合框架,并从数据级融合、特征级融合及决策级融合逐层剖析在线健康信息多层级融合的实现路径。

[Purpose/significance]It’s an important basis for developing health information knowledge-based services to effectively realize the organic fusion of multi-source and heterogeneous online health information.[Method/process]First,extract the main characteristics of the health information in the online medical and health platform according to the information generation method;then,according to the user’s goal,task and process of the medical and health information exploration and practice,the user’s online health information needs are hierarchically divided;furthermore,establish a response mechanism for user’s health information needs.[Result/conclusion]With that,construct a multi-level fusion framework of multi-source online health community information oriented to user demands,and then analyze the realization paths of multi-level fusion of multi-source online health community information from data-level fusion,feature-level fusion,and decision-level fusion.
