KB Labs

It's not just about data.
It's about connecting data with people.


KB Labs seeks to find new ways to combine the library’s digital cultural heritage collections and research, with the latest methods within machine learning. The lab is an initiative taken by the IT department at the Royal Danish Library.

Here you will find different applications made by the Royal Danish Library to visualize, engage or showcase the different materials or collections that we have available, to inspire and deepen the knowledge of what collections we actually have, and hopefully expand the use of these. Most of these applications and builds are in alpha or beta versions, and so will probably change over time. Feel free to contact us, if you have any questions or wish to know more about a given project.


JUXTA Visualisation

Image collections presented as collages, with seamless zooming from full collection to full-screen single images. Context-sensitive meta data with link-back to the originating sources makes it easy to explore large collections.

TAGS Visualisation

TAGS visualizes the use of HTML tags in the Royal Library's Danish Netarchive. In the app you can search and compare the use of different tags from 2007 until today.

ZOOM Visualisation

A serendipitous presentation of 1 million newspaper pages from Mediestream. For your convenience, the 20 terapixels from the scanned papers are packed into a single image. Only thing needed is to zoom a bit.

WORD2VEC Machine learning

Word2Vec is a high-dimensional word embedding based on an unsupervised machine learning algorithm using a simple neural network. It maps each unique word in a large text corpus to a vector.
The vector representation of the words reflects interesting semantic properties of the words. Words that appear in the same context will be close in the vector-space (similar words). But distance between words can also be used to find analogies. The word2vec demo features several corpora and a very large one based on over 65.000 Gutenberg E-books.

LOAR Dataset

LOAR (Library Open Access Repository) is an open access repository for long term preservation of research data. LOAR also contains some of the Royal Danish Library’s open data sets.
