Title As far as we know... - How to derive safe trust assertions from a limited amount of opinions
Abstract I will discuss the problems inherent the fusion of possibly disagreeing opinions about a certain fact. In particular, I will mainly focus on the analysis of event descriptions in the maritime domain where, by taking into account both provenance and uncertainty, I will try to derive reliable information from AIS messages sent by ships, collected via multiple sources and encoded as RDF statements. In order to accomplish such a task, I will make use of a probabilistic logic (Subjective Logic). Provenance information will be tracked using the Open Provenance Model.
