Graph Algorithms in SQL
Similarity Algorithm (Jaccard)
The Similarity algorithm is used to measure similarities between different sets of nodes or entities in a network. This is done by analyzing the data in each set and giving each set a score. The sets are then compared to each other and given a final score ranging between 0 and 1, where 0 is no match at all, 0.5 is a slight match, and 1 is a perfect match. Timbr’s GA library includes the popular Jaccard Similarity algorithm.
