Kinship contextualization: utilizing the preceding and following structural elements

The textual context of an element, structurally, contains traces of evidences. Utilizing this context in scoring is called contextualization. In this study we hypothesize that the context of an XML-element originated from its \textit{preceding} and \textit{following} elements in the sequential ordering of a document improves the quality of retrieval. In the tree form of the document's structure, \textit{kinship} contextualization means, contextualization based on the horizontal and vertical elements in the \textit{kinship tree,} or elements in closer to a wider structural kinship. We have tested several variants of kinship contextualization and verified notable improvements in comparison with the baseline system and gold standards in the retrieval of focused elements.
