Growing concerns about cyber-suicide have prompted many studies on suicide information available on the web. However, very few studies have considered non-English websites. We aimed to analyze online suicide-related information accessed through Chinese-language websites. We used Taiwan's two most popular search engines (Google and Yahoo) to explore the results returned from six suicide-related search terms in March 2016. The first three pages listing the results from each search were analyzed and rated based on the attitude towards suicide (pro-suicide, anti-suicide, neutral/mixed, not a suicide site, or error). Comparisons across different search terms were also performed. In all, 375 linked webpages were included; 16.3% of the webpages were pro-suicide and 41.3% were anti-suicide. The majority of the pro-suicide sites were user-generated webpages (96.7%). Searches using the keywords 'ways to kill yourself' (31.7%) and 'painless suicide' (28.3%) generated much larger numbers of harmful webpages than the term 'suicide' (4.3%). We conclude that collaborative efforts with internet service providers and search engines to improve the ranking of anti-suicide webpages and websites and implement online suicide reporting guidelines are highly encouraged.
对网络自杀的日益关注促使许多研究关注网络上的自杀信息。然而，很少有研究考虑非英语网站。我们旨在分析通过中文网站获取的在线与自杀相关的信息。我们使用台湾两个最受欢迎的搜索引擎（谷歌和雅虎）来探索 2016 年 3 月六个与自杀相关的搜索词的搜索结果。分析并根据对自杀的态度（支持自杀、反对自杀、中立/混合、非自杀网站或错误）对每个搜索的前三页结果进行了评分。还对不同搜索词进行了比较。共有 375 个链接网页被收录；16.3%的网页支持自杀，41.3%的网页反对自杀。大多数支持自杀的网站都是用户生成的网页（96.7%）。使用“自杀方法”（31.7%）和“无痛自杀”（28.3%）关键词的搜索产生了比“自杀”（4.3%）更多的有害网页。我们的结论是，鼓励与互联网服务提供商和搜索引擎合作，以提高反对自杀网页和网站的排名，并实施在线自杀报告指南。
