摘要: 随着智能手机和移动互联网的快速发展,人们的生活方式正在发生着变革。目前,智能手机终端集成了不同种类的传感器,如GPS、Wi-Fi、摄像头、麦克风等。通过内置传感器,可以搜集用户的相关信息,利用这些信息能有效地理解和识别用户行为,并为用户提供更好的个性化服务。文中主要面向大型工作或生活社区(如大学校园),提出基于背景声音识别的社会活动推荐系统MSSAR(Mobile Sound Sensing and Activity Recommender)。该系统通过音频传感器采集用户的背景声音,实时感知用户所处环境,并对用户实时活动(如在咖啡厅、在开会等)进行识别。MSSAR还能结合用户在线交互历史数据计算其偏好及社会关系亲密度,并据此为用户进行活动推荐。本系统基于以人为本的计算理念,对增强用户间社会联系、促进社区成员间活动交流具有积极意义。
