Let’s suppose you have assembled a large collection of papers (we’ll call that corpus) as a starting point for a literature review. Some of the first questions would be of an exploratory nature, you would like to get an intuition of what’s really in there. “Is there a certain structure, possibly a hidden bias I need to take into account? What is the coverage, are there some ‘holes’ in the data set, perhaps some missing months, or should I include another keyword in the search? How do certain keyword frequencies develop over time, is there a trend appearing?” We can help with getting this initial overview, and speeding up the process to get you working on the questions that really interest you.
