中文摘要：

移动群智感知是一种新的大规模感知模式,它利用随身携带的智能移动终端（智能手机、可穿戴设备等）形成大规模、随时随地且与人们日常生活密切相关的感知系统。通过广大用户参与获取的感知数据具有多模态、富内容、时空性、人本性等特征。以群智大数据为目标对象,就其感知、优选和理解等关键问题进行阐述和探讨,并对笔者在该领域的最新研究成果进行介绍。

英文摘要：

Mobile crowdsensing（MCS） has become an emerging paradigm for large-scale sensing. It empowers ordinary citizens to contribute data sensed or generated from their mobile devices（e.g., smartphones, wearable devices）, aggregates and fuses the data in the cloud for crowd intelligence extraction and human-centric service delivery. The data contributed by the crowd in MCS systems presents the features such as multi-modal, rich-content, spatio-temporal, and human-centric. The key challenges and techniques about crowdsensing big data were discussed. The recent progress of our group in this promising research area was described.
