to a table is identified by appending ‘SM’ to the
table name, followed by the name of the matrix.
For each similarity matrix:
Add SimilarityMatrix start tag to the XML document
and set the assocColumn and type attributes to their
corresponding values
For each cross reference:
Add crossRef start tag to the XML document
Add Value1, Value2, and Match elements and set
their corresponding values
Add crossRef end tag to the XML document
Add SimilarityMatrix end tag to the XML document
Query the database to get all fuzzy relations for the
current table. A fuzzy relation belonging to a table is
identified by appending ‘FR’ to the name of the
table, followed by the name of the relation
For each fuzzy relation:
Add FuzzyRelation start tag to the XML document
For each linguistic term:
Add LinguisticTerm start tag to the XML document
and set the term attribute to its corresponding value
Add FuzzySet start tag to the XML document
For each point in the fuzzy set:
Add the Point start tag to the XML document
Add x_value and membership elements and set their
corresponding values
Add Point end tag to the XML document
Add FuzzySet end tag to the XML document
Add LinguisticTerm end tag to the XML document
Add FuzzyRelation end tag to the XML document
Add the Table end tag to the XML document
Add the Database end tag to the XML document
5 CONCLUSIONS
We have described a fuzzy XML schema to
represent an implementation of a fuzzy relational
database that allows for similarity relations and
fuzzy sets. We have also provided a flat translation
algorithm to translate from the fuzzy database
implementation to a fuzzy XML document that
conforms to the suggested fuzzy XML schema.
