2SWS / 3 ECTS
|Time, Place||Thursday, 14:15 - 16:45, RvE seminar room|
|Course Syllabus||This course gives an overview of qualitative spatial representation and reasoning techniques. We survey the main aspects of representation of qualitative
knowledge including topology, distance, orientation and shape. Finally, we discuss some examples for the practical relevance of these representation and reasoning techniques.
This course is a seminar. It consists mainly of student presentations, but there will be some lectures as well. In the lectures, the instructor summarizes the conclusions of the presentations and gives an overview of the main issues of the topics.
The following article gives a good overview of this lecture:

|Informal Course Description||
Qualitative spatial reasoning plays an important role in many different application areas including Geographic Information Systems (GIS), computer vision, natural-language understanding, robot navigation, and common-sense reasoning. The following example is taken from a GIS and shall illustrate the relevance of QSR to our field of study.
The picture above shows a truck, a factory and a water protection area in between. The truck driver shall deliver goods to the factory without driving through the water protection area. What spatial operator do you need to get possible routes (the non-dotted orange line)? Feel free to test your solution in a GIS.
Even though GIS are commonly used in our days, there occur many problems during human-computer interaction, because spatial operators are not intuitive and do not support common-sense reasoning. To access this information we need systems that support our qualitative way of thinking. In this course we will discuss how spatial information can be represented such that humans can use and reason on it easily.
|Course Material||Reading for the course is a set of research articles supplied by the instructor online. A schedule of weekly readings will be published soon. Please come to class prepared to discuss the readings listed for that day.|
