Dealing with Missing/Incorrect Meta-Data

The Library Of Congress has a huge amount of historical data accessible through the American Memory collections. These collections include old videos, manuscripts, books, pictures and web archives. Collection items are usually associated with meta-data information which might be incorrect, missing or inconsistent with each other. Degraded quality of meta-data will result in low-quality search results. So one of the important directions that CADS people pursue, is to deal with such problem automatically. Projects accomplished in this area are listed below. These projects include different approaches to meta-data remediation. Chrono/Geo metadata remediation packages are available here for download, more packages are coming soon.
