Rich and correct metadata still plays a central role in accessing data sources in a semantic fashion. However, at the time of content creation it is often virtually impossible to foresee all possible uses of content and to provide all interesting index terms or categorizations. Therefore semantic retrieval techniques have to provide ways of allowing access to data via missing metadata, which is...

While many Learning Content Management Systems are available, the collaborative, community-based creation of rich e-learning content is still not sufficiently well supported. Few attempts have been made to apply crowd-sourcing and wiki-approaches for the creation of elearning content. In this article, we showcase SlideWiki -an Open Courseware Authoring platform supporting the crowdsourced creat...

The automatic discovery and clustering of morphologically related words is an important problem with several practical applications. This paper describes the evaluation of word clusters carried out through crowd-sourcing techniques for the Maltese language. The hybrid (Semitic-Romance) nature of Maltese morphology, together with the fact that no large-scale lexical resources are available for M...

This paper presents the u-map, a user-centric crowd-sourcing QoE-based geo-database recommendation system that enables clients to upload information about their profile, their quality-of-experience (QoE) feedback for a service, traffic demand, network/spectrumconditions (e.g., interference, coverage), providers, and their position (e.g., GPS-based measurements) in a spatio-temporal geo-database...

We have recently proposed a mathematical framework for crowd-sourcing of biomedical image analysis and diagnosis through digital gaming. Here we review our recent progress on this gaming platform and demonstrate its viability for telediagnosis of malaria, achieving an accuracy that is within less than 2 percent of that of a trained expert.

This paper presents a collaborative annotation framework for person identification in TV shows. The web annotation frontend will be demonstrated during the Show and Tell session. All the code for annotation is made available on github. The tool can also be used in a crowd-sourcing environment.

We present the CISpaces framework, a collaborative virtual space for intelligence analysts for the elaboration of information to explain a situation. CISpaces supports the analysis of conflicting information in collaboration exploiting argumentation schemes to structure and share analyses, crowd-sourcing to collect information and provenance to establish the credibility of hypotheses.

Learning a second language is becoming a more popular trend around the world. But the act of learning another language in a place removed from native speakers is difficult as there is often no one to correct mistakes nor examples to imitate. With the idea of crowd sourcing, we would like to propose an efficient way to learn a second language better.

We present a test-bed for Emergency Management Simulations by contrasting two prototypes we have built, CAVIAR and Reverse 111. We outline the desirable design principles that guide our choices for simulating emergencies and implement these ideas in a modular system, which utilizes proactive crowd-sourcing to enable emergency response centers to contact civilians co-located with an emergency, t...

Living the economic dream of globalization in the form of a locationand timeindependent world-wide employment market, today crowd sourcing companies offer affordable digital solutions to business problems. At the same time, highly accessible economic opportunities are offered to workers, who often live in low or middle income countries. Thus, crowd sourcing can be understood as a flexible socia...
