Abstract

Despite considerable number of studies on risk factors for asthma onset, very little is known about their relative importance. To have a full picture of these factors, both categories, personal and environmental data, have to be taken into account simultaneously, which is missing in previous studies. We propose a framework to rank the risk factors from heterogeneous data sources of the two categories. Established on top of EventShop and Personal EventShop, this framework extracts about 400 features, and analyzes them by employing a gradient boosting tree. The features come from sources including personal profile and life-event data, and environmental data on air pollution, weather and PM2.5 emission sources. The top ranked risk factors derived from our framework agree well with the general medical consensus. Thus, our framework is a reliable approach, and the discovered rankings of relative importance of risk factors can provide insights for the prevention of asthma.

习惯与环境:到底是什么导致了哮喘?
尽管对哮喘发病的危险因素进行了大量的研究,但对它们的相对重要性知之甚少。为了全面了解这些因素,必须同时考虑个人和环境数据这两类因素,而这在以前的研究中是缺失的。我们提出了一个框架来对这两类的异构数据源中的风险因素进行排序。该框架建立在EventShop和Personal EventShop的基础上,提取了约400个特征,并采用梯度增强树对其进行分析。这些功能的来源包括个人资料和生活事件数据,以及空气污染、天气和PM2.5排放源的环境数据。从我们的框架中得出的排名靠前的风险因素与一般的医学共识非常一致。因此,我们的框架是一种可靠的方法,并且发现的风险因素相对重要性的排名可以为哮喘的预防提供见解。
