背景在线Web服务的长期可用性对于确保分析结果的再现性至关重要。然而，由于验收后缺乏维护，许多服务器在短时间内变得不可用。我们的目的是监测的可访问性和发布的Web服务的衰减率，以及确定潜在的趋势changes.Methods的因素，我们搜索PubMed，以确定出版物包含Web服务器相关的条款之间发表的1994年和2017年。使用自动和手动筛选来检查每个Web服务的状态。Kruskall-Wallis，Mann-Whitney和卡方检验被用来评估各种参数，包括可用性，可访问性，平台，作者的来源，引文，期刊影响因子和publication year.Results我们确定了3649出版物在375种期刊，其中2522（69%）目前活跃。95%以上的网站在前2年运行，但这一比率在第3年下降到84%，随后逐渐下降（P
Background The long-term availability of online Web services is of utmost importance to ensure reproducibility of analytical results. However, because of lack of maintenance following acceptance, many servers become unavailable after a short period of time. Our aim was to monitor the accessibility and the decay rate of published Web services as well as to determine the factors underlying trends changes.Methods We searched PubMed to identify publications containing Web server-related terms published between 1994 and 2017. Automatic and manual screening was used to check the status of each Web service. Kruskall-Wallis, Mann-Whitney and Chi-square tests were used to evaluate various parameters, including availability, accessibility, platform, origin of authors, citation, journal impact factor and publication year.Results We identified 3649 publications in 375 journals of which 2522 (69%) were currently active. Over 95% of sites were running in the first 2 years, but this rate dropped to 84% in the third year and gradually sank afterwards (P
