IIS: Deduplication Test Case
Immunization Information Systems Home (IIS) pages:
NIP has developed a toolkit to assist immunization information systems (IIS) in the evaluation of their deduplication algorithms. This toolkit will help registries assess their system's ability to prevent/remove duplicate records. The data and procedures in this toolkit can help identify strengths and weaknesses in the deduplication algorithms. The test data set consists of test cases that are representative of known duplicate record problems in real data, based on the information provided by various IIS personnel. These test cases are fictitious examples; they do not correspond to information on real children. The evaluation tool application will calculate sensitivity and specificity values for the IIS's algorithms based on the test results. The sensitivity value measures how well the system performs at recognizing known duplicate records. The specificity is the value that reflects how accurate the duplicate record detection is by measuring the rate at which non-duplicate records are misidentified.
Download deduplication toolkit
- Click on the above link to download a zip file containing the toolkit components:
- Toolkit User Manual (EvaluationToolManual.doc) - a document that will guide the user through installation of the tool and use of the test data set
- Evaluation Tool (DupEval.cab) - a program that will calculate sensitivity and specificity values for an IIS's deduplication algorithm
- Test Data Set (DupTestData.csw) - a file containing test cases representative of known duplicate record problems
- Run the setup.exe program to install the Evaluation Tool on a PC. *Note that for older Windows 95 systems you may first need to run DCOM98.exe which is included in the kit.
