we introduce a method based on attribute dependence
which integrates the data instance information and structure information to supply matching.At first
we calculated the degree of attribute dependence according to the data instance information
and further establish the graph of attribute dependence and calculated the degree of the degree of structure similarity according to the graph of attribute dependence.At last
the paper gets the mapping between attributes according to the degree of structure similarity.Experiments are conducted and the results show that this algorithm is better than other algorithms in various performance metrics.
