在本文中,我们提出了一个以社区为中心的药物滥用监测和支持系统,称为DrugTracker,它利用社交媒体和地理空间数据在近实时。通过该系统,用户可以:(1)从社交媒体平台检测药物滥用风险行为,例如,Twitter;(2)通过查询具有关键字、空间实体和时间约束的合并和实时数据集来分析药物滥用风险行为;以及(3)通过基于Web的用户界面以主题分区图、热图和统计图表探索查询结果和相关数据。为了保护Twitter用户的隐私,其数据被收集,该系统自动隐藏推文中的重新识别元素,并将地理标签聚合到人口普查区等区域。出于演示目的,我们的DrugTracker系统填充了一个数据库,其中包含2017年的约1000万条推文,这些推文被我们的深度学习模型注释为药物滥用风险行为。
In this paper, we present a community-focused drug abuse monitoring and supporting system, called DrugTracker, that utilizes social media and geospatial data in near real-time. Through the system, users can: (1) Detect drug abuse risk behaviors from social media platforms, e.g., Twitter; (2) Analyze drug abuse risk behaviors by querying consolidated and live datasets with keywords, spatial entities, and time constraints; and (3) Explore the query results and associated data through a web-based user interface in thematic choropleth, heatmap, and statistical charts. To protect the privacy of the Twitter users, whose data is collected, the system automatically hides the re-identification elements in tweets and aggregates the geo-tags into areas such as census tracts. For the demonstration purpose, our DrugTracker system is populated with a database that contains about 10 million tweets from the year 2017, that were annotated as drug abuse risk behavior positive by our deep learning model.
