Our Goal

is to revolutionize discovery of scientific knowledge. We are building a visual interface that dramatically increases the visibility of research findings for science and society alike. We are a non-profit organization and we believe that a better way to explore and discover scientific knowledge will benefit us all.


Get an overview of a research topic: knowledge maps provide an instant overview of a topic by showing the main areas at a glance, and papers related to each area. This makes it possible to easily identify useful, pertinent information.

Separate the wheat from the chaff: we cluster similar papers together. This makes it easier to identify relevant content when you are searching for an ambiguous term, or when you would like to identify content from a single discipline in a multidisciplinary field.

Identify relevant concepts: one of the most difficult tasks when you are new in a research field is to learn the “language” of the field. Open Knowledge Maps makes it easier for you by labeling research areas with relevant concepts.

Find open content: our knowledge maps include both closed and open access papers. However we highlight open access papers - and the majority of those papers can be read from within the interface. And if not, the fulltext is only a click away.

How it works


An Open Knowledge Maps visualization presents you with a topical overview for your search term. It is based on the 100 most relevant documents for your search term.


We use text similarity to create the knowledge maps. The algorithm groups those papers together that have many words in common.


The visualization is intended to give you a head start on your literature search. You can also use Open Knowledge Maps to stay up-to-date - just limit your search to the most recent papers in the options.
