Abstract

Purpose Adequate means for easily viewing, browsing and searching knowledge graphs (KGs) are a crucial, still limiting factor. Therefore, this paper aims to present virtual properties as valuable user interface (UI) concept for ontologies and KGs able to improve these issues. Virtual properties provide shortcuts on a KG that can enrich the scope of a class with other information beyond its direct neighborhood. Design/methodology/approach Virtual properties can be defined as enhancements of shapes constraint language (SHACL) property shapes. Their values are computed on demand via protocol and RDF query language (SPARQL) queries. An approach is demonstrated that can help to identify suitable virtual property candidates. Virtual properties can be realized as integral functionality of generic, frame-based UIs, which can automatically provide views and masks for viewing and searching a KG. Findings The virtual property approach has been implemented at Bosch and is usable by more than 100,000 Bosch employees in a productive deployment, which proves the maturity and relevance of the approach for Bosch. It has successfully been demonstrated that virtual properties can significantly improve KG UIs by enriching the scope of a class with information beyond its direct neighborhood. Originality/value SHACL-defined virtual properties and their automatic identification are a novel concept. To the best of the author’s knowledge, no such approach has been established nor standardized so far.

利用虚拟属性加强对知识图谱的查看、浏览和搜索

目的方便地查看、浏览和搜索知识图谱（KGs）的适当手段是一个关键因素，但仍然是一个限制因素。因此，本文旨在提出虚拟属性作为本体和知识图谱有价值的用户界面（UI）概念，以改善这些问题。虚拟属性提供了 KG 上的快捷方式，可以用直接邻域之外的其他信息来丰富类的范围。它们的值通过协议和 RDF 查询语言 (SPARQL) 按需计算。本文展示了一种有助于识别合适的候选虚拟属性的方法。虚拟属性可以作为通用的、基于框架的用户界面的整体功能来实现，这些用户界面可以自动提供用于查看和搜索 KG 的视图和遮罩。研究结果该虚拟属性方法已在博世公司实施，超过 100,000 名博世员工可以在富有成效的部署中使用该方法，这证明了该方法在博世公司的成熟性和相关性。它成功地证明了虚拟属性可以通过丰富一个类的范围，使其具有超出其直接邻域的信息，从而显著改善 KG 的用户界面。据笔者所知，迄今为止还没有建立过这种方法，也没有将其标准化。

期刊介绍： ACS Applied Bio Materials is an interdisciplinary journal publishing original research covering all aspects of biomaterials and biointerfaces including and beyond the traditional biosensing, biomedical and therapeutic applications. The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates knowledge in the areas of materials, engineering, physics, bioscience, and chemistry into important bio applications. The journal is specifically interested in work that addresses the relationship between structure and function and assesses the stability and degradation of materials under relevant environmental and biological conditions.
