I have no experience with fuzzy matching but it sounds a lot like finding Nearest Neighbours to me. It could be techniques used with Nearest Neighbours also help with your problem: Multidimensional scaling is a nice way to visualise distances between objects: https://en.wikipedia.org/wiki/Multidimensional_scaling https://en.wikipedia.org/wiki/Multidimensional_scaling A review of Nearest Neighour techniques might be interesting: https://arxiv.org/abs/1007.0085 https://arxiv.org/abs/1007.0085 Also, if you stick with just a similarity score, something like a ROC curve can help to pick a cutoff: https://en.wikipedia.org/wiki/Receiver_operating_characteristic https://en.wikipedia.org/wiki/Receiver_operating_characteris...
