Freebase has 40,760 https://www.freebase.com/query?autorun=1&q=%5B%7B%22%2Fbase%2Fwordnet%2Fsynset%2Fequivalent_topic%22%3A%5B%7B%22id%22%3Anull%7D%5D%2C%22return%22%3A%22count%22%7D%5D WordNet synsets mapped to equivalent Freebase topics and another 2,300 mapped to broader topics. This could be used to bootstrap any efforts in this space. Of course, it's out of a total of almost 118,000 synsets, so it's only 35-40% coverage, but it probably covers the most popular/common topics. Something to be careful of is semantic drift in Wikipedia/Wikidata, since these alignments were originally done back in 2009.
Here's the schema https://www.freebase.com/base/wordnet/?schema= for the types associated with Wordnet in Freebase. (Yes, I know types are evil and illegal in Wikidata, but just consider them collections of properties grouped together for human organizational convenience.)
BTW, I agree with Daniel that care is needed here. It's easy for casual observers to get confused about what should be connected, particularly since Wikipedia articles aren't necessarily divided along strict semantic lines.

Hi!
Is there a property for WordnetId?
More mappings are always good. The case of WordNet is a bit tricky though, since WordNet is about words, not concepts. Wikidata items can perhaps be mapped to SynSets, but we still have to be careful not to get confused about the semantics.
