【摘要】:[目的/意義]針對(duì)我國(guó)科技專家?guī)旖ㄔO(shè)分散、共享困難等問(wèn)題,通過(guò)構(gòu)建統(tǒng)一的科技專家信息語(yǔ)義模型實(shí)現(xiàn)對(duì)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(guò)程]以知識(shí)組織理論為基礎(chǔ),構(gòu)建科技專家語(yǔ)義模型,從6個(gè)主要方面將分散、異構(gòu)的專家信息進(jìn)行語(yǔ)義化描述、關(guān)聯(lián)與聚合,并采用RDF進(jìn)行形式化描述和實(shí)證研究,最終生成具有較強(qiáng)規(guī)范性和語(yǔ)義關(guān)系的專家信息庫(kù),為實(shí)現(xiàn)異構(gòu)專家信息的共建、共享與服務(wù)提供堅(jiān)實(shí)基礎(chǔ)。[結(jié)果/結(jié)論]實(shí)驗(yàn)結(jié)果表明,采用知識(shí)組織模型和方法,能夠在語(yǔ)義層面對(duì)專家信息進(jìn)行多維度語(yǔ)義化描述、關(guān)聯(lián)和推理,并最終實(shí)現(xiàn)專家信息的有效聚合,在專家?guī)旖ㄔO(shè)、專家發(fā)現(xiàn)和知識(shí)組織方面有重要價(jià)值。[局限]需要對(duì)專家信息語(yǔ)義模型的領(lǐng)域適用性和信息更新機(jī)制進(jìn)行持續(xù)優(yōu)化,實(shí)現(xiàn)與知識(shí)組織工具的深度關(guān)聯(lián)與服務(wù)。
[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.
