The dependability of systems and networks has been the target of research for many years now. In the 1970s, what is now known as the top conference on dependability-The IEEE/IFIP International Conference on Dependable Systems and Networks (DSN)-emerged gathering international researchers and sparking the interest of the scientific community. Although it started in niche systems, nowadays dependability is viewed as highly important in most computer systems. The goal of this work is to analyze the research published in the proceedings of well-established dependability conferences (i.e., DSN, International Symposium on Software Reliability Engineering (ISSRE), International Symposium on Reliable Distributed Systems (SRDS), European Dependable Computing Conference (EDCC), Latin-American Symposium on Dependable Computing (LADC), Pacific Rim International Symposium on Dependable Computing (PRDC)), while using Natural Language Processing (NLP) and namely the Latent Dirichlet Allocation (LDA) algorithm to identify active, collapsing, ephemeral, and new lines of research in the dependability field. Results show a strong emphasis on terms, like 'security', despite the general focus of the conferences in dependability and new trends that are related with 'machine learning' and 'blockchain'. We used the PRDC conference as a use case, which showed similarity with the overall set of conferences, although we also found specific terms, like 'cyber-physical', being popular at PRDC and not in the overall dataset.
多年来，系统和网络的可靠性一直是研究的目标。20世纪70年代，如今被视为可靠性领域顶级会议的——IEEE/IFIP可靠系统与网络国际会议（DSN）——应运而生，汇聚了国际研究人员并引发了科学界的兴趣。尽管它始于小众系统，但如今可靠性在大多数计算机系统中被视为极为重要。这项工作的目标是分析在久负盛名的可靠性会议（即DSN、软件可靠性工程国际研讨会（ISSRE）、可靠分布式系统国际研讨会（SRDS）、欧洲可靠计算会议（EDCC）、拉丁美洲可靠计算研讨会（LADC）、环太平洋可靠计算国际研讨会（PRDC））论文集上发表的研究，同时使用自然语言处理（NLP），即潜在狄利克雷分配（LDA）算法，来识别可靠性领域中活跃、衰退、短暂和新的研究方向。结果表明，尽管这些会议总体聚焦于可靠性以及与“机器学习”和“区块链”相关的新趋势，但仍非常强调诸如“安全”之类的术语。我们以PRDC会议为例，它与会议整体情况相似，不过我们也发现了一些特定术语，比如“网络物理”，在PRDC会议上很流行，但在整个数据集中并非如此。
