A survey of ground-truth in emotion data annotation
2012
2012 IEEE International Conference on Pervasive Computing and Communications Workshops
Preserved Fulltext
This paper aims to solve the problem of lack of ground-truth in emotion data and consequently to advance the accuracy of emotion recognition systems. ...
Then, it digs in deep into the data acquisition and annotation stage and reveals the major criteria for obtaining a ground-truth emotion set. ...
The lack of ground-truth occurs in the training data collected where the validity of the labels provided for each measurement is doubtful. ...

In the project being studied, problematization processes lead to the constitution of referential databases called 'ground truths' that enable both the effective shaping of algorithms and the evaluation ...
Working as important common touchstones for research communities in image processing, the ground truths are inherited from prior problematization processes and may be imparted to subsequent ones. ...
Acknowledgements I am immensely grateful to the members of the computer science laboratory who let me follow their activities and more generally helped me with the research. ...
