Probabilistic record matching

WebbIn a deterministic approach, matches are detected as exact matches; a record has the same similarities. The algorithms use patterns and rules to conclude that records are matching. Probabilistic matching identifies the likelihood of matches based on a scoring threshold. Let’s say that three parts of a record match. http://cs229.stanford.edu/proj2013/Murciano-Goroff-ProbabilisticRecordMatching.pdf
