Merging is a fundamental operation in revision control systems that enable integrating different changes made to the same documents. In open platforms, such as Wikipedia, uncertainty is ubiquitous, essentially due to a lack of knowledge about the reliability of contributors. The authors propose in a version control framework designed for uncertain multi-version tree-structured documents, based on a probabilistic XML (eXtensible Markup Language) model. In this paper, they define a merge operation that complements their framework and enables the conciliation of uncertain versions.
