Many XML retrieval applications require relevance-oriented ranking of retrieved elements in order to capture the vagueness inherent to the information retrieval process. This relevance-oriented ranking should not only support vagueness at the content level, but also at the structural level. In this paper, we use a probabilistic object-relational framework to model representation and retrieval strategies that take into account vagueness at both content and structure level. Our approach makes use
