Merging multiple and frequently contradictory sources of information has been identified as a significant issue in the semantic web community. In addition, pieces of information to be combined are provided with uncertainty due, for instance, to the reliability of sources.
To solve this, possibility theory offers a useful tool for representing and reasoning with uncertain, partial, and inconsistent information. In this paper, we concentrate on dance video processing, in which many inconsistent information sources exist. Therefore, we propose possibilistic merging operators for the dance OWL2-EL ontologies to deal with the conflicting dance sources.
We represent an extension of EL within a possibility theory setting. It leverages a min-based operator to merge the ontologies based on possible distributions. Furthermore, the semantic fusion of these distributions has a natural syntactic counterpart when dealing with EL ontologies. The min-based fusion operator is recommended when distinct dance sources that provide information are dependent.
