Enable users to SEARCH and QUERY databases

Enable users to DESIGN databases GoogleForms, FormsAssembly, SurveyMonkey, REDCap

A user-designed form A New Database

(a collection of interconnected tables)

Some Algorithms

Dissertation Project Accommodate Changing User Needs

FormMapper

- Form understanding - Equivalent elements discovery - Birthing new database elements

Dissertation Project The FormMapper Tool

6

Objective: To evolve a high-quality database.

Solution: Novel Techniques

Re-use Existing

Experiments in Healthcare 52 clinical forms 6 databases: 35-500 tables

84.5% match with gold standard

74% high-quality

Form FormMapper Database Evolved

Database

Quality of evolved databases could be improved … … if the terms used on forms are standardized (clinically encoded)
