International Workshop on 
CROwd-Powered e-Services
CROPS 2019

Call for papers


Short Description and Goals

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(aka “human computation”) 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.

The CROPS workshop seeks to become a forum to discuss 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.

Submission Guidelines

Authors should submit original, unpublished research papers. All papers must not simultaneously be submitted to another journal or conference. There are two types of submissions:

  • Full Paper submissions have a maximum of 12 pages.

  • Short Paper submissions have a maximum of 6 pages.

Papers and abstracts should be submitted through the submission web site in PDF format. Authors should follow the Springer formatting for Lecture Notes on Computer Science as indicated here:   

By submitting a paper, authors implicitly agree that at least one of them will register to the conference and present the paper. It is expected that at least one author will register for each accepted paper. Only papers that have been presented by their authors during the conference will be published in the conference proceedings. 

The proceedings of the I3E 2019 workshops are planned to be published as a book with the main conference proceedings by Springer-Verlag in its Lecture Notes in Computer Science (LNCS) series.
