In my thesis I am writing about a number of different metrics. Not metrics in the mathematical sense, but metrics which are measures, functions. A function which takes an input and returns a symolic value.
There are different metrics, most of them are taken from other papers, some are my own invention. They are based on adjectives:
- weighted completeness
- richness of information
Obviously, these words are nouns, but are these proper nouns, too? My guess is yes, because they are very specific and they are not general known in a lot of areas, but a comparable small research field.
Examples of their usage can be found in this PhD thesis. There it was used in both ways: capitalized and lowercase. Apparently, in composition with metric lowercase and without capitalized.
“While straightforward, the simple completeness metric does not reﬂect how humans measure the completeness of a instance.”
— p.112 
“For the Weighted Completeness, also a table containing the pre-calculated alpha values should be available”
— p.113 
What is correct?
