No problem @Bob_Jansen perhaps I think of stop words differently, I mean a list of publicly known stop words such as “the, and, it”.
Warning ! grammar has never being my strong point, but with age I hope comes wisdom 
I like your term “go words” I would think of these as words you have nominated or perhaps even “go phrases”.
- I am not saying such go words or phrases could not have stop words included, but when you remove common words, verbs, common nouns a smaller list is available that may relate to a proper noun.
- Lets highlight these “special words” in context, and provide the tool to register them as “go words or phrases” the simplest method is to create a tiddler title.
For example lets say we remove common words and find one in the text “Galactic”, it may be next to a possible verb, “Federation” and when we look at the actual text we see “This was when “The Galactic Federation” was born”. The capitalisation is also a give away, Our attention has being focused here because the word Galactic was identified. We select “The Galactic Federation” and create a tiddler, perhaps indicating it is a proper noun.
- Any future reference to the The Galactic Federation will be highlighted and links made automatic if you use free links.
- Most content and text, will have a limited number of proper nouns and if your attention is drawn to them you can systematically build a list of those in the content, create tiddlers for them, and even store more info in them like a glossary.
- You could even collate all proper nouns used across multiple wikis
- Perhaps you can only highlight “special words” with mid sentence capitalisation.
Through taking an approach like this there is value in identifying potential proper nouns, then select actual proper nouns, and having the opportunity to provide more information eg “The Galactic Federation” `head quarters on Earth". Notice we just found another? “Earth”.
- Using some other ideas rather than create a tiddler just linking eg [[Earth]] it becomes a missing tiddler, and something you can list or retrieve.
- There is other values in seeing “special words” in your text because it helps draw inferences while you are highlighting proper nouns.
- The process is cumulative and the exceptions decrease rapidly over time.
See a discussion I started some time ago that explored some advanced ideas we could implement in tiddlywiki Wordsmithing stop words, verbs past and present tense - #2 by TW_Tones
This subject has led me back to some prior discussions that is all related in a broader sense including Measure of order in a tiddlywiki
