面向知识服务的领域知识结构研究

由于大数据的时代背景以及不同用户群体间的知识服务需求存在个性化差异的现实情况,本文认为在设计领域知识结构时应充分考虑用户需求和数据动态性的特点,并以此为基础设计了一套可分领域知识结构。首先,本文梳理了大数据时代下知识服务的特点并给出了以用户为主导的领域知识服务模式;其次,根据该服务模式,本文提出了一套从知识服务视角出发的可分领域知识结构;最后,结合领域大数据转化为领域知识的过程给出了该知识结构的构建流程。本文设计的知识结构在方便领域信息库扩充的同时,也从实际问题角度出发满足了用户的个性化需求。

Research on Domain Knowledge Structure Oriented to Knowledge Services

As user groups and knowledge organization are rapidly changing in the big data environment,this study proposes a domain knowledge structure oriented to knowledge services.First,the characteristics and challenges of knowledge organization and knowledge service in the era of big data are summarized,after which the process of transforming domain big data into domain knowledge is detailed.Second,considering that the demand for information varies among different user groups even in the same field,we present divisible domain knowledge structures from the perspective of knowledge services,which not only facilitates the organization of knowledge but also satisfies personalized needs.Finally,combining this with the process of transforming domain big data into domain knowledge,we present the construction process of the knowledge structure.
