Summary of IMPACT project & results by Hildelies Balk (KB, IMPACT Project Director)

Hildelies Balk continued with an summary overview of the IMPACT project achievements. Content holders, researchers and industry partners have worked together for the last 4,5 years to tackle each step in the digitisation workflow. All tools have been evaluated in different scenario”™s on the IMPACT dataset and show improvement on the state of the art. Preliminary test with the Dutch historical lexicon and the ABBYY FineReader Engine 10 for example demonstrated a 15% increase of words found, which is of great benefit to the end user.
