This paper presents a distributed collaborative approach to XML document clustering. According to a previous study, XML documents are mapped to a transactional domain, based on a data representation model which exploits the notion of XML tree tuple. This XML transactional model is well-suited to the identification of semantically cohesive substructures from XML documents, according to structure as...

In contrast to traditional, "sharp" data representation models, uncertain data objects can be represented in terms of an uncertainty region over which a probability density function (pdf) is defined. In this context, the focus has been mainly on partitional and density-based approaches, whereas hierarchical clustering...
