Measuring Relational Similarity with VSM The measure of similrity of R1 and R2 is given by the cosine of the angle Ɵ between r1 and r2: cosine = ∑ r1, i. r2, i = r1. r2 = r1. r2

Starting from algebraic operations and simple analytical functions such as sine and cosine, the algorithm randomly re-combines previous equations and parameters, and tests each set of expressions for accuracy against the empirical data, until it reaches a desired level of accuracy.
