【摘要】：[目的/意義]針對我國科技專家?guī)旖ㄔO分散、共享困難等問題,通過構(gòu)建統(tǒng)一的科技專家信息語義模型實現(xiàn)對專家信息統(tǒng)一描述和共享,以打破專家信息孤島、提高專家?guī)炖眯�。[方法/過程]以知識組織理論為基礎,構(gòu)建科技專家語義模型,從6個主要方面將分散、異構(gòu)的專家信息進行語義化描述、關(guān)聯(lián)與聚合,并采用RDF進行形式化描述和實證研究,最終生成具有較強規(guī)范性和語義關(guān)系的專家信息庫,為實現(xiàn)異構(gòu)專家信息的共建、共享與服務提供堅實基礎。[結(jié)果/結(jié)論]實驗結(jié)果表明,采用知識組織模型和方法,能夠在語義層面對專家信息進行多維度語義化描述、關(guān)聯(lián)和推理,并最終實現(xiàn)專家信息的有效聚合,在專家?guī)旖ㄔO、專家發(fā)現(xiàn)和知識組織方面有重要價值。[局限]需要對專家信息語義模型的領域適用性和信息更新機制進行持續(xù)優(yōu)化,實現(xiàn)與知識組織工具的深度關(guān)聯(lián)與服務。
[Abstract]:[objective / significance] in order to break the isolated island of expert information, the unified description and sharing of expert information can be realized by constructing a unified semantic model of scientific and technological experts' information, aiming at the problems of scattered construction and difficult sharing of scientific and technological experts' database in China. Improve the efficiency of expert pool utilization. [method / process] based on the theory of knowledge organization, the semantic model of scientific and technological experts is constructed, which describes, correlates and aggregates the scattered and heterogeneous expert information from six main aspects. Finally, the expert information database with strong normative and semantic relations is generated, which provides a solid foundation for the co-construction, sharing and service of heterogeneous expert information. [results / conclusions] the experimental results show that the knowledge organization model and method can be used to describe, correlate and infer the expert information at the semantic level, and finally realize the effective aggregation of the expert information and build the expert database. Expert discovery and knowledge organization are of great value. [limitations] it is necessary to continuously optimize the domain applicability and information updating mechanism of the expert information semantic model, and to realize the deep association and service with the knowledge organization tools.
