Job description The Department of Geo Information Processing (GIP) is a vibrant, multi-disciplinary scientific team, specializing in methods and techniques for processing (acquiring, organizing, analyzing) spatio-temporal data and information, and in building tools (models, algorithms, visualizations) that improve our understanding of complex and dynamic spatial systems and help in decision-making at multiple spatial and temporal scales.

Job description

The Department of Geo Information Processing (GIP) is a vibrant, multi-disciplinary scientific team, specializing in methods and techniques for processing (acquiring, organizing, analyzing) spatio-temporal data and information, and in building tools (models, algorithms, visualizations) that improve our understanding of complex and dynamic spatial systems and help in decision-making at multiple spatial and temporal scales.

The Living Textbook is an ontology-based learning tool. Students can be guided through this ontology-based concept map by means of linear learning pathways defined by the teacher. From literature, we found that non-linear or tree-like structures for learning pathways might be more suitable.

Currently, this ontology is visualised as a concept map that can become very large and cluttered when the number of concepts and relationships in the ontology are high. Different visualisation methods exist to enhance the readability of concept maps and network diagrams in general. At this moment, it is unknown which type of visualisation will support learning and understanding knowledge graphs in the best possible way.

You will:

develop ideas to improve the visualisation of the concept map and of the learning paths.
prototype those ideas in the Living Textbook and conduct research on their effectiveness for learning.
select suitable visualisation type(s) taking into account different types of learners and teaching approaches.
address the problem of cluttering in the diagram, through methods of clustering/filtering.
determine the type of learning which is triggered by using ontologies, as implemented in the Living Textbook.
design a method to integrate ontologies of different knowledge fields in the Living Textbook to support students’ knowledge integration and knowledge transfer.

You have to conduct a literature review on these topics and come up with a state-of-the-art proposal for implementing new functionality in the Living textbook. This has then to be tested through a prototype with different groups of students in the ITC usability lab and improved based on its findings. The final prototype needs to be implemented in small scale education settings and then research can be done on the learning outcomes of the students working with this.
