High-level overview of the system. The figure shows the high-level overview of the system. We evaluate a subset of user-contributed tags and use it to build the annotator reputation model. We evaluate the remaining set of the tags based on semantic similarity measures and subjective logic. The unevaluated tags are then ranked based on the annotator reputation model and the model serves as a basis to accept or reject the unevaluated tags from the users.
