Special Issue Information

Dear Colleagues,

Crowdsourcing is a model in which individuals or organizations obtain goods and services from a large, open and rapidly-evolving group of Internet users. The idea of dividing work between participants to achieve a cumulative result has been applied successfully in many areas, from biology and linguistics to engineering and cultural heritage. As a particular branch of crowdsourcing, crowd computing (also known as “human computation” or “human-centered AI”) systematizes the intertwining of human intelligence with artificial intelligence, aiming to solve tasks that are hard for individuals or computers to do alone. The key principles include (i) automation: machines do non-creative and repetitive work, providing a cascade of knowledge for humans to evaluate; (ii) micro-tasking: work is broken into small tasks that are easier to complete by humans chosen specifically on the grounds of their expertise; and (iii) mixed crowd: a greater volume of work, and of greater value, can be completed when specialists and open communities work together.

This Special Issue seeks to become a forum to publish broad, interdisciplinary research about human-in-the-loop intelligent e-services, human-AI interaction, and techniques for augmenting the abilities of individuals and communities to perform whichever tasks. We thereby solicit papers presenting theoretical contributions or practical uses of crowdsourcing and crowd computing models in any domains of application. Topics of interest include, but are not limited to, the following:

  • Crowdsourcing/crowd computing case studies:
    • digital humanities,
    • economy,
    • education,
    • health,
    • journalism,
    • software engineering,
    • tourism,
    • urban data collection,
  • Crowdsourcing/crowd computing theory and techniques:
    • algorithm design,
    • collective knowledge,
    • human-AI interaction,
    • incentives to collaboration,
    • intellectual property,
    • macro- and micro-tasking,
    • mixed crowd,
    • psychological and emotional aspects of crowd involvement,
    • quality control,
    • task assignment,
  • Uses of crowdsourcing/crowd computing:
    • games,
    • knowledge bases,
    • fact verification,
    • information retrieval,
    • machine learning,
    • optimization,
    • virtual labor markets,

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
