I was a bit miffed that “currency” was not considered to be related to “mark”. Similarly I thought I’d found the perfect word between “ski” and “trust”, “mogul”, but once again your program disagreed.
Also, please help the player understand the basis of the word relations. I was surprised that the shortest path between “investor” and “mark” was a non-dictionary word: “zuckerberg”. Presumably you are not using WordNet but some corpus of embeddings. If you say where he corpus comes from I can tailor my guesses. Conversely though, the shortest path feature is good because it teaches me what works. Maybe a top 5 would be even better.
You’re onto something though, keep at it!
