Urban crowd logistics, also known as last-mile crowdsourcing [1], consists in leaning on a group of citizens for completing the last-mile delivery of parcels in a city. This model answers the need to cope with the increased congestion in cities and the resultant problems of inefficiency and negative environmental impacts of local deliveries.

Reading List of Spatial Crowdsourcing

1 minute read

Published:

Spatial crowdsourcing is an extension of general crowdsourcing. Specifically, in spatial crowdsourcing, crowd or workers need to physically move to a particular place associated with a spatial task. In different branch areas of computer science, this new topic has different names, such as spatial crowdsourcing, mobile crowdsourcing and participatory sensing. Here is a reading list about this topic. I will update it aperiodically.

Notes for Uploading Academic Paper to arXiv

Published:

“The arXiv is a repository of electronic preprints, known as e-prints, of scientific papers in the fields of mathematics, physics, astronomy, computer science, quantitative biology, statistics, and quantitative finance, which can be accessed online. In many fields of mathematics and physics, almost all scientific papers are self-archived on the arXiv. Begun on August 14, 1991, arXiv.org passed the half-million article milestone on October 3, 2008, and hit a million by the end of 2014. By 2014 the submission rate had grown to more than 8,000 per month.”–WiKi
