== Introduction
-String similarity helps answer questions like:
+String similarity tries to answer the question: is one word
+(or phrase, sentence, paragraph, document) the same as another.
+This is an important capability in many scenarios involving searching
+or asking questions or invoking commands.
+It can help answer questions like:
* Are two Jira/GitHub issues duplicates of the same issue?
* Are two (or more) customer records actually for the same customer?

* As a doctor, can I find a medical journal paper discussing a patient's
medical diagnosis/symptoms/treatment?
* As a programmer, can I find a solution to my coding problem?
+Very simple cases can typically be explicitly catered for by hand, e.g.

+assert ['color', 'Colour'].every { it =~ '[Cc]olou?r' }

+Handling cases explicitly like this soon becomes tedious.
+We'll look at some libraries which can help us handle comparisons
