Crowdsourcing and Open Data


Crowdsourcing Platform

  • Fundamental Aspects of Crowdsourcing Platforms
  • High Quality Crowd-Workflow Design
  • Combination of Human Computation and AI


  • Motivation of Workers
  • Gamification in Volunteer Crowdsourcing
  • Personalized/adaptive Design to Increase Performance
  • Quality Control Mechanisms (Data Reliability, Agreement)

Application of Crowdsourcing

  • Data Generation and Data Verification
  • Crowd-based Skill Assessment and Expert Sourcing
  • Crowd- and AI-based Translation Workflows
  • Crowd- and AI-based Text Summarization Workflows
  • Crowd- and AI-based Knowledge Graph and Chatbot Supporting Workflows
  • Internal Crowdsourcing (employee sourcing)
  • Gaming QoE Assessment using Crowdsourcing
  • Speech Quality Assessment using Crowdsourcing approach (ITU-T Standardization)
  • Text Simplification and Text Complexity: einfaches-wiki.de


Our research extends to the following areas:

Building on Crowdsourcing

- 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. )


Improving Crowdsourcing

- 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)
