3.4.6.1: Inner Product

The inner product sums the products of the vector entries. Vectors with many non zero entries have a higher probability to achieve high values. Vectors with larger entries get higher values This means that longer documents have a higher probability to get high similarity values.

This leads to weak experimental results.
