Integrating machine learning (ML) and natural language processing (NLP) into the MeeToo app to create a state of the art suicide prevention solution for children and young people (CYP) aged 11+.The MeeToo app delivers free, safe, anonymous, pre-moderated, peer support to 56k CYP. MeeToo has been independently evaluated and demonstrated to improve mental health in CYP (AFC, 2021).In 2020, MeeToo supported 794 CYP expressing suicidal ideation. When suicidal ideation becomes suicidal intent, CYP don't seek support because they feel they have 'gone past help' (Biddle\_2020). Because 40% of CYP who die by suicide have no contact with the mental-health system (Rodway\_2020), suicide prevention tools which only focus on CYP in crisis exclude the majority who go on to take their lives (Kessler\_2019). Successful suicide prevention solutions must deliver increased support before distress becomes acute.Our innovation, MeeTooSaives, developed in collaboration with Bristol University Medical School and University of Sussex Department of Informatics, integrates ML and NLP into the MeeToo app to interrogate passive as well as high risk, data to identify risk patterns, analyse semantic content and predict risk.When risk patterns are detected, CYP are automatically stepped-up into a suicide support stream for clinical supervision and trained responder peer support. NLP integrates smart links to topic matched resources. Crucially, CYP doesn't have to ask for additional support. When distress deescalates, support steps down and CYP re-join their peers. AI continues to monitor risk.Because most suicides occur between midnight and 4 a.m. (Perlis\_2016) mirror provision in Australia facilitates 24/7 global delivery.MeeTooSaives is important because suicide is the leading cause of death in UK CYP (ONS\_2018) and for every suicide, there are 20 non-fatal suicide attempts (WHO\_2018). By the age of 17, 7.4% of UK CYP have attempted suicide (Millenium\_Cohort\_Study\_2021). In 2017, 72% of UK CYP suicides were male; 14% were black/minority ethnic; 5% were LGBT (NCISH\_2017).The lifetime cost of one youth suicide is £9.75 M (Platt\_2006) yet the estimated 10 year ROI for every £1 invested in suicide prevention is £39.11(McDaid\_2017). Late intervention in youth mental health costs public services an estimated £17bn a year (Oppenhim, 2015). The UK spends £49.7 M PA treating paracetamol poisoning alone (Bateman\_2014). This high risk, technically challenging innovation could provide the 2M UK CYP with mental health issues with 24/7, 365-day, access to crisis and continuous support for <£40M P.A.

将机器学习（ML）和自然语言处理（NLP）集成到MeeToo应用程序中，为11岁以上的儿童和青少年（青少年）创建一个最先进的自杀预防解决方案。MeeToo应用程序为56 k用户提供免费，安全，匿名，预先审核的同伴支持。MeeToo已被独立评估并证明可改善青少年的心理健康（AFC，2021）。在2020年，MeeToo支持了794名表达自杀意念的青少年。当自杀意念变成自杀意图时，自杀者不会寻求支持，因为他们觉得自己已经“失去了帮助”（Biddle\_2020）。由于40%的自杀死亡者与心理健康系统没有联系（Rodway\_2020），自杀预防工具只关注危机中的自杀者，排除了大多数继续自杀的人（Kessler\_2019）。成功的自杀预防解决方案必须在痛苦变得严重之前提供更多的支持。我们的创新MeeTooSaives与布里斯托大学医学院和苏塞克斯大学信息学系合作开发，将ML和NLP集成到MeeToo应用程序中，以询问被动和高风险数据，以识别风险模式，分析语义内容并预测风险。当检测到风险模式时，自杀者会自动升级为自杀支持流，以进行临床监督和训练有素的响应者同伴支持。NLP将智能链接集成到主题匹配资源。最重要的是，谷歌不必要求额外的支持。当痛苦减轻时，支持者会下台，重新加入他们的同伴。AI继续监测风险。由于大多数自杀发生在午夜至凌晨4点之间（Perlis\_2016），澳大利亚的镜像服务有助于全球全天候提供服务。MeeTooSaives很重要，因为自杀是英国人死亡的主要原因（ONS\_2018），每起自杀，有20起非致命自杀企图（WHO\_2018）。到17岁时，7.4%的英国人曾试图自杀（千禧研究2021）。2017年，72%的英国自杀者为男性; 14%为黑人/少数民族; 5%为LGBT（NCISH 2017）。一名青少年自杀的终身成本为975万英镑（Platt 2006），但每投资1英镑预防自杀的10年投资回报率估计为39.11英镑（McDaid 2017）。对青少年心理健康的后期干预估计每年花费公共服务170亿英镑（Oppenhim，2015）。英国仅治疗扑热息痛中毒就花费了4970万英镑（Bateman 2014）。这种高风险、技术上具有挑战性的创新可以为2 M英国精神健康问题患者提供24/7365天的危机处理和持续支持，年收入<4000万英镑。
