Mining Social Media Messages for HIV Testing and Prevention Communication

项目摘要 SARS-CoV-2在美国的传播已经产生了新的问题， 父母授权使用尖端的大数据技术来处理大量不同的数据（文本，视频， 图像），以选择符合艾滋病毒生物医学需求的可操作和可接受的社交媒体艾滋病毒信息 美国目标县。这些问题包括：（a）我们目前选择的信息与 大流行病的背景和当前的机器学习方法需要数月时间才能优化;（B） 组合SARS-CoV-2/HIV信息是必要的，但产生它们的方法还没有被开发出来。 （c）没有验证增加稀少信息或新信息的方法。紧急情况- 补充申请要求资源来抵消这些问题，并利用机会来产生 关于艾滋病毒和应对流行病的新知识。我们的新方法将成功地使用相同的 经过测试的技术，以选择，产生，并提供有关艾滋病毒的组合信息（即，测试，PrEP，和 避孕套使用）和有关社交距离、检测、预防和治疗SARS-CoV-2的信息， 男男性接触者（Men Who Have Sex With Men，MSM）目前的大流行病也提醒人们， 男男性行为者缺乏疫苗接种;因此，补充项目将整合有关疫苗的信息， 包括最终的一个针对SARS-CoV-2的。为了解决由于缺乏足够的资金而产生的新问题， 为SARS-CoV-2提供适当的艾滋病毒信息，并调整目前的方法， 在这样一个不断变化的环境中，消息传递既耗时又不灵活，因此我们需要（1）新的快速方法 （2）将联合收割机艾滋病毒建议与 新出现的与SARS-CoV-2相关的公共卫生建议;以及（3）快速增加 在社交媒体上发布的信息。因此，本次融资申请将追求以下目标：目标1。延伸 确定与SARS-CoV-2大流行和疫苗有关的区域需求的现行方法，目标2。 为流行病部署新的快速消息选择方法，目标3。实验测试 通过发送（a）所选择的实验消息（结合到 本地服务信息）提供给社交媒体账户的管理者，以及（B）随机选择 向一组对照县发送HIV/SARS-CoV-2信息。这一重大创新项目将 在沟通和说服、大数据方法、公共卫生和 贝叶斯时空建模，并通过心理学领域领先机构的参与， 公共卫生和计算机科学。该项目与新的数据收集工作具有协同作用， 美国男性互联网调查，现在将收集SARS-CoV-2血清阳性率数据， 补充，以进行本申请中提出的项目的额外行为数据。

PROJECT SUMMARY The spread of the SARS-CoV-2 in the US has created novel problems with methods successfully underway in the parent grant that use cutting edge, Big Data techniques for processing vast and diverse data (text, videos, images) to select actionable and acceptable social media HIV messages that match the HIV biomedical needs of target US counties. These problems include: (a) the messages we are currently selecting are not relevant in the context of the pandemic and the current machine learning methods take many months to optimize; (b) combination SARS-CoV-2/HIV messages would be necessary but the methods to produce them have not been developed; and (c) no methods to multiply scarce or new messages have been validated. This emergency- supplement application requests the resources to offset these problems and to use the opportunity to generate new knowledge about HIV and responses to pandemics. Our new approach will use the same successfully tested techniques to select, generate, and deliver combination messages about HIV (i.e., testing, PrEP, and condom use) and messages about social distancing, testing, prevention, and treatment of the SARS-CoV-2, specifically for Men who have Sex with Men (MSM). The current pandemic also serves as a reminder that vaccination is lacking in MSM; therefore, the supplemental project will integrate messaging about vaccines, including an eventual one against SARS-CoV-2. To counteract the new problems resulting from insufficient numbers of appropriate HIV messages for the SARS-CoV-2 times and to adapt current methods which are too time-consuming and inflexible for messaging in such a changing environment, we need (1) new, rapid methods to identify actionable and acceptable messages; (2) new methods to combine HIV recommendations with emerging public health recommendations related to SARS-CoV-2; and (3) new methods to rapidly multiply the resulting messages for social media. Thus, this funding application will pursue the following: Aim 1. Extend current methods to identify regional needs related to the SARS-CoV-2 pandemic and vaccines, Aim 2. Deploy new rapid methods of message selection for a pandemic, and Aim 3. Experimentally test the effect of the new methods by sending (a) the selected experimental messages (combined with links to local service information) to managers of social media accounts and (b) a random selection of HIV/SARS-CoV-2 messages to a group of control counties. This significant and innovative project will be facilitated by unique team expertise in communication and persuasion, Big Data methods, public health, and Bayesian spatio-temporal modeling, and by the participation of leading institutions in the areas of psychology, public health, and computer science. The project is synergistic with new data collection efforts associated with the American Men Internet Survey, which will now collect SARS-CoV-2 seroprevalence data, which will be supplemented to conduct additional behavioral data for the project proposed in this application.
