In the last decade, we have seen the emergence of two big families of datasets: the public and the private ones. Invaluable public datasets like Wikipedia, Wikidata, Open Corporates and others have been created and leveraged by organizations world-wide. However, as great as they are, most organization still rely on private datasets of their own curated data.

In this article, I want to demonstrate how high-value private datasets may be integrated into the Cognonto’s KBpedia knowledge base to produce a significant impact on the quality of the results of some machine learning tasks. To demonstrate this impact, I have created a demo that is supported by a “gold standard” of 511 web pages taken at random, to which we have tagged the organization that published the web page. This demo is related to the publisher analysis portion of the Cognonto demo. We will use this gold standard to calculate the performance metrics of the publisher analyzer but more precisely, we will analyze the performance of the analyzer depending on the datasets it has access to perform its predictions.
