Linkages between research outputs are crucial in the scholarly knowledge graph. They include online citations, but also links between versions that differ according to various dimensions and links to resources that were used to arrive at research results. In current scholarly communication systems this information is only made available post factum and is obtained via elaborate batch processing. In this paper we report on work aimed at making linkages available in real-time, in which an alternative, decentralised scholarly communication network is considered that consists of interacting data nodes that host artifacts and service nodes that add value to artifacts. The first result of this work, the "Event Notifications in Value-Adding Networks" specification, details interoperability requirements for the exchange real-time life-cycle information pertaining to artifacts using Linked Data Notifications. In an experiment, we applied our specification to one particular use-case: distributing Scholix data-literature links to a network of Belgian institutional repositories by a national service node. The results of our experiment confirm the potential of our approach and provide a framework to create a network of interacting nodes implementing the core scholarly functions (registration, certification, awareness and archiving) in a decentralized and decoupled way.
翻译:研究产出之间的联系在学术知识图中至关重要,它们包括在线引用,但也包括不同版本之间的链接,这些版本因不同方面和用于取得研究成果的资源的链接而不同。在目前的学术通信系统中,这种信息只提供事后信息,并且是通过精心分批处理获得的。在本文中,我们报告了旨在实时提供联系的工作,其中认为有替代的、分散的学术通信网络,由相互互动的数据节点组成,该节点将存放艺术品和服务节点增加文物的价值。这项工作的第一个成果是“增值网络中的晚报”的规格,详细说明了利用链接数据通知交换与文物有关的实时生命周期信息的互操作性要求。在一项实验中,我们将我们的规格应用于一个特定的使用案例:通过国家服务节点向比利时的机构储存库网络分配Scholix数据-内链链接。我们的实验结果证实了我们的方法的潜力,并提供了一个框架,用以建立一个互动节点网络,在分散和分层方式上执行核心学术职能(登记、认证、认识和归档)。
