中文简介:
研究领域的本体论是表征、探索和分析研究景观的重要工具。一些研究领域由大规模分类法全面描述,例如生物学中的MeSH和物理学中的PhySH。相反,当前的计算机科学分类法是粗粒度的,并且往往发展缓慢。例如,ACM分类方案仅包含约2K个研究主题,上一版本可追溯到2012年。在本文中,我们介绍了计算机科学本体(CSO),这是一个大规模的、自动生成的研究领域本体,包括大约15K个主题和70K个语义关系。它是通过在1600万篇科学文章的非常大的数据集上应用Klink-2算法创建的。CSO与其他分类相比有两个主要优势:i)它包含大量其他分类中没有的主题;ii)可以通过在最近的出版物语料库上运行Klink-2来自动更新。CSO为Springer Nature编辑团队采用的几种工具提供支持,并已用于实现各种解决方案,如对研究出版物进行分类、检测研究社区和预测研究趋势。为了促进对CSO的理解,我们开发了CSO门户,这是一个web应用程序,用户可以下载、探索并提供不同级别的CSO详细反馈。用户可以使用门户对主题和关系进行评级,建议缺失的关系,并将本体的部分可视化。该门户将支持CSO的定期发布和获取,目的是为从事学术数据的各个社区提供全面的资源。
课程简介: Ontologies of research areas are important tools for characterising, exploring, and analysing the research landscape. Some fields of research are comprehensively described by large-scale taxonomies, e.g., MeSH in Biology and PhySH in Physics. Conversely, current Computer Science taxonomies are coarse-grained and tend to evolve slowly. For instance, the ACM classification scheme contains only about 2K research topics and the last version dates back to 2012. In this paper, we introduce the Computer Science Ontology (CSO), a large-scale, automatically generated ontology of research areas, which includes about 15K topics and 70K semantic relationships. It was created by applying the Klink-2 algorithm on a very large dataset of 16M scientific articles. CSO presents two main advantages over the alternatives: i) it includes a very large number of topics that do not appear in other classifications, and ii) it can be updated automatically by running Klink-2 on recent corpora of publications. CSO powers several tools adopted by the editorial team at Springer Nature and has been used to enable a variety of solutions, such as classifying research publications, detecting research communities, and predicting research trends. To facilitate the uptake of CSO we have developed the CSO Portal, a web application that enables users to download, explore, and provide granular feedback on CSO at different levels. Users can use the portal to rate topics and relationships, suggest missing relationships, and visualise sections of the ontology. The portal will support the publication of and access to regular new releases of CSO, with the aim of providing a comprehensive resource to the various communities engaged with scholarly data.
