An Approach of Mining Exceptions in Multi-Database Based on Users' Interest

Mining exceptions is an important topic in data mining.This paper proposes an approach of mining exceptions in multi-database based on users' interest.First,users provide data object of their interest.Then we select relevant data with respect to users' interest.Through analysis of every database locally to obtain local patterns and then synthesis,we can obtain exceptions.We also evaluate our algorithm experimentally.It is validated that our algorithm is effective and efficient.
