Information Retrieval and Its Sister Disciplines

This article presents a summary graph to show the relationships between Information Retrieval (IR) and other related disciplines. The figure tells the key differences between them and the conditions under which one would transition into another. When I studied Machine Learning (ML), my favorite figure among all was "The Table of Common Distributions" in Casella and Berger's 2002 book "Statistical Inference". It appeared in the book's appendix. Every time when I saw this figure, I was in awe.
