The project

The Metadata Quality Assurance Framework is a research project on figuring out how can we decide in an algorithmical way whether a metadata record in a cultural heritage database is “good” or “bad”. During the project I will create a general framework, which lets metadata repositories and digital libraries (such as Europeana, TextGrid or Digital Public Library of America) to run a range of measurements on the collection, and get suggestion where they should improve the quality of their metadata.

These pages are about the process of the research – my early findings, results, codes, talks.
