Abstract

This paper focuses to a problem domain where several imperfect context recognition devices with restricted resources are located in the same context. The main aim of the paper is to compare different collaborative decision making methods in this domain. In particular, the focus is on certain voting mechanisms and confidence evaluation metrics. Also computational, space, and communication requirements of the discussed methods are discussed briefly. The methods are tested with a real-world dataset containing data from several sport activities. In addition, an online context recognition platform that is capable to make distributed context recognition decisions is introduced briefly.
