A multimedia XML data is a collection of multiple types of data sets tagged by XML elements. Such an XML data can be retrieved not only by a Boolean connection with keywords but also by tag-element-based query languages. In many cases, however, keywords-based queries result in either too many hits or too few results. It is not either clears what to formulate when we expect a 驴good驴 size of query results.This paper proposes a method of schema extraction for multimedia XML data. Schemas are then levelized with respect to the frequency of topological document structures in a database. The topological structural information of these schemas is used to formulate queries and to rewrite queries for relaxation and restriction.
