Community-based Crowdsourcing – Our paper at WWW2014 SOCM

by Marco Brambilla, posted in social network

Today Andrea Mauri presented our paper “Community-based Crowdsourcing” at the SOCM Workshop co-located with the WWW 2014 conference.

SOCM is the 2nd International Workshop on the Theory and Practice of Social Machines and is an interesting venue for discussing instrumentation, tooling, and software system aspects of online social network. The full program of the event is here.

Our paper is focused on community-based crowdsourcing applications, i.e. the ability of spawning crowdsourcing tasks upon multiple communities of performers, thus leveraging the peculiar characteristics and capabilities of the community members.
We show that dynamic adaptation of crowdsourcing campaigns to community behaviour is particularly relevant. We demonstrate that this approach can be very e ffective for obtaining answers from communities, with very di fferent size, precision, delay and cost, by exploiting the social networking relations and the features of the crowdsourcing task. We show the approach at work within the CrowdSearcher platform, which allows con figuring and dynamically adapting crowdsourcing campaigns tailored to different communities. We report on an experiment demonstrating the eff ectiveness of the approach.

The figure below shows a declarative reactive rule that dynamically adapts the crowdsourcing campaign by moving the task executions from a community of workers to another, when the average quality score of the community is below some threshold.

The slides of the presentation are available on Slideshare. If you want to know more or see some demos, please visit:

The full paper will be available on the ACM Digital Library shortly.

Search Computing demonstration at WWW 2010, Hyderabad, India

by Marco Brambilla, posted in Uncategorized

Together with Alessandro Bozzon, I’ve presented a demonstration of the search computing exploratory search paradigm at WWW 2010.

The demonstrated scenario is in the real estate and job search field. Suppose that a user is willing to find a new job with a specific expertise and in a certain city. Based on his findings, he also wants to search for housing opportunities in the closeby neighbourhoods. Hence, he wants to check for additional information on the quality of life in the area, on availability of services (public transportation, schools for his children, and so on). The final decision will be based on a complex function of all these aspects. The figure below shows the graph of actually existing and registered searchable concepts within this scenario. All these concepts are searched through third-party services.

 
Here is a short video with a summary of the demonstration:

Here you can see Alessandro at work, while demonstrating the approach to some visitor (big prize if you guess who he is:) :

Btw, if you are looking for some more exciting pictures I took in Hyderabad, India you can have a look at this Flickr set of pictures from Hyderabad (while at WWW 2011).
