Is journalism in the text/video/audio business, or is it in the knowledge business? This class we’ll look at this question in detail, which gets us deep into the issue of how knowledge is represented in a computer. The traditional relational database model is often inappropriate for journalistic work, so we’re going to concentrate on so-called “linked data” representations. Such representations are widely used and increasingly popular. For example Google recently released the Knowledge Graph. But generating this kind of data from unstructured text is still very tricky, as we’ll see when we look at th Reverb algorithm.
