eye view of the available XML data will be helpful to the user in many
ways. The goal is to build semantic XML document summaries which
present the important information available in an XML document to
the user. In the best case, such a summary is a concise replacement for
the original document itself. At the other extreme, it should at least
help the user make an informed choice as to the relevance of the
document to his needs. We focus on two main issues in producing such
meaningful and concise summaries: i) Which information units of the
XML document are important and should be included in the summary?
ii) How to generate a semantic summary of different sizes?
