Enter the terms or Concept Unique Identifiers (CUIs) whose similarity or relatedness you wish to compute into the fields labeled Term 1 and Term 2. You can enter any combination of terms or CUIs. For example:
You can than either calculate the two terms similarity or relatedness. Semantic similarity measures quantify how ``alike'' (or similar) two concepts are by determining their closeness in a hierarchy. Semantic relatedness measures quantify the degree of semantic feature overlap between two terms. Two terms may be related (needle-thread) but not necessarily similar.
To calculate the similarity you have two options:
To calculate hte relatedness you also have two options:
