中文简介:
生物医学本体是巨大的:BioPortal存储库中的几个本体包含数千甚至数十万个实体。这种大型本体的开发和维护是困难的。为了支持本体作者和存储库开发人员的工作,提高我们对生物医学研究人员如何探索、查询、重用和在下游应用中使用这些本体的理解至关重要。我们通过分析几年来不同访问模式下的BioPortal交互日志,对BioPortal本体库中的用户活动进行了探索性实证分析。我们调查了BioPortal的用户如何查询和搜索本体及其类,他们如何探索本体,以及他们如何重用来自不同本体的类。此外,通过三个真实场景,我们不仅分析了本体在注释任务中的使用,还将其与BioPortal用户的浏览和查询行为进行了比较。在我们的研究中,我们使用了几种不同的可视化技术。为了一目了然地检查大量的交互、重用和真实世界使用数据,我们使用并扩展了PolygOnto,这是一种可视化方法,在以前的工作中已成功用于分析本体的重用。我们的结果表明,探索、查询、重用和实际使用行为很少一致,这表明不同的用户倾向于探索、查询和使用本体的不同部分。最后,我们强调并讨论BioPortal用户之间的差异和共性。
课程简介: Biomedical ontologies are large: Several ontologies in the BioPortal repository contain thousands or even hundreds of thousands of entities. The development and maintenance of such large ontologies is difficult. To support ontology authors and repository developers in their work, it is crucial to improve our understanding of how these ontologies are explored, queried, reused, and used in downstream applications by biomedical researchers. We present an exploratory empirical analysis of user activities in the BioPortal ontology repository by analyzing BioPortal interaction logs across different access modes over several years. We investigate how users of BioPortal query and search for ontologies and their classes, how they explore the ontologies, and how they reuse classes from different ontologies. Additionally, through three real-world scenarios, we not only analyze the usage of ontologies for annotation tasks but also compare it to the browsing and querying behaviors of BioPortal users. For our investigation, we use several different visualization techniques. To inspect large amounts of interaction, reuse, and real-world usage data at a glance, we make use of and extend PolygOnto, a visualization method that has been successfully used to analyze reuse of ontologies in previous work. Our results show that exploration, query, reuse, and actual usage behaviors rarely align, suggesting that different users tend to explore, query and use different parts of an ontology. Finally, we highlight and discuss differences and commonalities among users of BioPortal.
