摘要

The paper analyses searchers' assessments of usefulness and specificity on different levels of granularity in XML-coded documents. Documents are assessed on 10 usefulness/specificity combinations and on the granularity levels of article, section, and subsection. Overlapping judgements show a remarkable lack of consistency between searchers. There is an inverse relationship between articles and sections both in the assessment of specificity and of usefulness, indicating that retrieval on different granularity levels are a useful feature of a retrieval system. Searchers find the full article more useful when they assess the same document both on the article and section level indicating that there is a need to provide context to the sections and subsections when presenting result list of XML-documents.
