XML document, schema extraction,
XML documents, which are becoming new standard for
expressing and exchanging data in the Internet, don't have
defined schema. It is not adequate to directly apply XML
documents to the existing SQL or OQL. Research on how
to extract schema for XML documents and query
language is going on actively. For users' query, the results
could be too many or too less. It is important to give the
users adequate results. This paper suggests the way to
extract many levelized schema according to the frequency
of element occurrence in XML documents. The Schema
can be reduced or extended to correspond to the users'
query more flexibly.
