LITERATURE SURVEY-REFERENCE PAPER-7

Usher:Improving Data Quality with Dynamic Forms:Kuang Chen ,Harr Chen, Neil Conway , Joseph M. Hellerstein , Tapan S. Parikh 

-Data quality is a critical problem in modern db.

-It is used of detecting and mitigating errors.


-Here present USHER, an end to end system for form design,entry & data quality assurance.


-It learns a probabilistic model over question of the form.


-It mainly done in two step,First by learning the  relationship between form question via structure    learning &  second by estimating the parameters of a Bayesian network.


-Which help to generate predictions &error probabilities

  for the form.

-This develop an adaptive form system for data entry,which can be dynamically changed according to  previous data input by the user.
