Research Interests

Currently, my main research area is engineering and science of the Web, in particular data-based information systems on the Web.

Web Information Systems: The Web Information Systems (WIS) group focuses on research & education in data-based information systems on the Web and making them more effective in retrieving, processing and interpreting data generated by humans and machines. The overall mission of the WIS research group is:

• to develop a deep understanding of the construction and use of web-based information systems,
• to develop novel methods, techniques, and tools that advance the way in which web-based information systems are constructed and used, and
• to offer students education that prepares them for a leading role in web-based information systems science and technology.

Focus: In the Web Information Systems research group, we aim at making web information systems more effective in retrieving, processing and interpreting data generated by humans and machines.

Objectives:

• To understand what human‐ and machine-generated web data represents in terms of people’s actions, interests, intents, and behaviors on the web.
• To develop new solutions to meet the fundamental challenges in how systems effectively attribute and exploit semantics for human‐ and machine-generated data, given the size and dynamic nature of the web.

Approach: Our approach towards our objectives of understanding and developing, combines four main research areas:

• Data Management
• Human Computing & Human-Centered AI
• Information Retrieval
• User Modeling & Explainability
