Accuracy, F1, or TPR (a.k.a recall or sensitivity) are well-known and widely used metrics for evaluating and comparing the performance of machine learning based classification.

Most of us would probably like to work in a profession recognised for its legality, decency and honesty. At least I hope so. In my line of work, what we have right now is palpable evidence that the IT industry lacks a reliable moral compass.

Understanding how data converts from data to information to intelligence can be seen in the flow across the databases in an enterprise. What is a data warehouse? How do we get Business Intelligence? In this video I explain the high level view of how large corporations like Dell evolve their data to the front-end BI applications.

A NoSQL database from MarkLogic provides the Royal Society of Chemistry (RSC) with the ability to unlock a treasure trove of assets.  Now the RSC can publish three times as many journals and four times as many articles. It also gave the Society the ability to develop new educational applications to make chemistry accessible to a wider audience.

Modern approaches to information products replete with full text search have the power to transform your business.  Built on an enterprise…
