基于主体行为的非结构化数据模型

Model for unstructured data based on subject behavior

为满足用户的复杂检索需求,对用户行为特性进行分析,提出一种非结构化数据的星系数据模型。基于对文件系统中属性使用情况的统计结果,通过优化文件属性、增加用户行为特性属性等方法,形成非结构化数据属性集。在此基础上,使用一个数据对象和基本类、内容类、特征类、行为类、环境类等5个属性类表示一个非结构化数据,构建非结构化数据模型。对模型进行了仿真分析,分析结果表明了模型有效且可行,具有轻量级、支持复杂检索、检索结果准确度高等优势,为大数据管理提供支撑。

To satisfy the complex retrieval needs of users, subject behavior characteristics are analyzed, Galaxy Data Model for unstructured data is constructed. Based on the statistical results of the use of file attributes, by using optimizing the file attributes, user behavior characteristics related attributes is added, and unstructured data attribute sets are formed. One data object and five attributes class including basic, content, characteristics, behavioral and environmental are used to describe an unstructured data. A simulation example is presented to prove the feasibility and validity of the proposed model. Consequently, the study offers referenced model and solution for big data management.
