What Is Mobile Crowdsensing? 2018/11/29 wanglong127@gmail.com, PLA UST

Mobile Crowdsensing = Crowdsourcing + Mobile Devices + Sensing 众包+移动设备+感知 众包思想的兴起 移动设备的普及 移动设备的感知能力的大范围提高 Mobile Crowdsensing = Crowdsourcing + Mobile Devices + Sensing 2018/11/29 wanglong127@gmail.com, PLA UST

wanglong127@gmail.com, PLA UST Crowdsourcing is a powerful new way to gain innovative solutions. The term was coined to describe the process of outsourcing a task to an independent 'crowd' of experts who compete (or sometimes collaborate) to solve the problem. They are often rewarded for doing so. 2018/11/29 wanglong127@gmail.com, PLA UST

wanglong127@gmail.com, PLA UST Mechanical Turk A story in the Middle Ages A crowdsourcing Internet marketplace 过去一个月来，我断断续续地参与了在亚马逊旗下最奇怪的生意：亚马逊土耳其机器人 我给色情行业打过工。 我做过有好几百个问题的调查问卷，透露了我的精神状况和政治倾向。我审查过网络内容。我帮助学校教师抓过抄袭者。我吹捧过房地产。为了多拿几美分我毁掉了自己的社交网络。 我的进账：13.25美元 “亚马逊土耳其机器人”是一种众包网络集市，雇主通过此Web服务可以提交一个任务请求，worker可以选择完成任务，并获得报酬，这个任务不是由计算机完成的，而是由服务后台的人工完成。 重要理念：将电脑无法完成的无数琐碎的脑力工作自动化 2018/11/29 wanglong127@gmail.com, PLA UST
