Tanimoto Coefficient

The Tanimoto Coefficient is a measure used to compare the similarity between two sets or objects, often in chemistry or data analysis. It is calculated by dividing the size of the intersection (common parts) of the two sets by the size of their union (all parts combined). The value ranges from 0 to 1, where 0 means no similarity and 1 indicates identical sets. In essence, it quantifies how much two items share relative to their total content, providing a clear metric for comparing similarity in various applications.
