同一领域不同知识概念之间存在演化关系,分析演化关系能有效地梳理领域知识的发展脉络,然而网络知识的碎片化、无序性、大规模等特性使得用户很难准确地分析并获取知识之间的这种关系。针对该问题,本文提出一种基于时空域联合建模的领... 同一领域不同知识概念之间存在演化关系,分析演化关系能有效地梳理领域知识的发展脉络,然而网络知识的碎片化、无序性、大规模等特性使得用户很难准确地分析并获取知识之间的这种关系。针对该问题,本文提出一种基于时空域联合建模的领域知识演化脉络分析方法,该方法首先考虑将知识系统以时空域联合知识网络的形式进行表达,随后采用骨架聚类方法提取历年知识网络演化路径,并按知识概念的发展进行演化路径衔接及路径分析。以数字媒体领域知识为例的实验分析表明,该方法能有效提取按年份发展的领域知识演化路径,对于辅助用户进行领域知识的理解与学习,以及个性化推荐具有显著的价值。 展开更多

The China-US Million Book Digital Library Project (Million Book Project) is an intemational cooperation program between China and the US. However, one million digitized books are considered not to be the ultimate goal of the project, but a first step towards universal access to human knowledge. In particular, there are four challenges about the new way to analyze, process, operate, visualize and interact with digital media resource in this library. To tackle these challenges, North China Centre of Million Book Project (in Chinese Academy of Sciences) has initiated several innovative research projects in areas such as multimedia content analysis and retrieval, bilingual services, multimodal information presentation, and knowledge-based organization and services. In this keynote speech, we simply review our work in these areas, and argue that by technological cooperation with these innovation research topics, the project will develop a top-level digital library platform for the million book library. 展开更多
