Our research extends to the following areas:
- Mobile crowdsourcing (in the field)
- Crowd assessments: Usability, UX, QoE
- Privacy and confidentiality in crowdsourcing
- Mobile street application, urban mobility, city guarding
- Data collection in the field: crowd as (continuous) sensors
- Data management (clean, index, verify, tag, label, translate, etc. )
- Real-time interaction, human computation as a service, (HuaaS)
- Privacy and security in crowdsourcing
- Motivation in crowdsourcing, gamification
- Quality control (pattern recognition, cheater detection, anomaly)
- Automatic user segmentation (clustering)
- Training, E-learning and building expert-crowds
- Task complexity modeling
- Crowd and user biases, subjective normalization
- Scalable Crowdsourcing, Robustness, Reliability in Engineering
- Quality in Crowdsourcing (quality of opinion, audio/video, reliability)
