针对高校图书馆机构知识库构建中普遍存在的数据来源与组织难题,通过文献数据预处理和数据模型的设计,将高校科研成果的文献数据原貌保存到机构知识库中,并实现文献实体与高校实体间的精准关联。基于模型继续探索文献数据规律,发现题录实体分布中普遍存在的“二八”定律现象对于拥有海量、动态科研成果数据的机构知识库的管理和运营具有主要参考价值。
Aiming at the problems of data source and organization which are common in the construction of university library’s knowledge base, the original data of the university’s scientific research achievements are saved to the institutional repository through document data preprocessing and data model design, Accurate correlation between entities. Based on the model, we continue to explore the law of document data and find that the phenomenon of “28 ”, which is ubiquitous in the distribution of bibliographic entities, has great reference value for the management and operation of institutional repository with massive and dynamic data of scientific research achievements.
