Why are some words within a mention different colors or bolded?

When looking at mentions within the 'detail' section, you may notice that some words appear as green, red or in bold font. This feature was designed to easily allow you to diagnose why a mention was classified as either a positive or negative mention and which category the mention belongs to, whether it be Food, Beverage, Service, Ambiance, Intent on Return, or Value. 

Any terms in green font (ex: craving) indicates a positive term. Any terms in red font (ex: waiting) indicates a negative term, and any terms in bold font indicates why the mention was classified as one of the six categories (listed above).
