ABSTRACT
Now that we have our entities and relationships, what remains is to put these to use for the purpose of making a new hypothesis or discovery of some kind-deriving a potential fact that does not literally appear in the published text given as input but is derived as a result of taking everything digested into account. Because of the complexity and heterogeneity involved in understanding the physical world as it actually exists, this is usually a daunting problem. Some simplications and approximations are typically desirable. ere are limitless possibilities for how to make use of these approximate models of reality so that we retain the important information and communicate insight. We will describe here a few that have proven useful in our attempts to accelerate discovery. We present these roughly in order of increasing complexity and sophistication.
