To calculate the similarities, the authors used the spreading activation network based on Wikipedia and WordNet [8]. Most existing algorithms have been designed to achieve serendipity measured by artificial evaluation metrics due to the lack of publicly available datasets containing user feedback ...
We can also hold one of the values n (or m) fixed and sweep across the other to calculate, for instance, how the recall increases in the viewport as the member would scroll down the page. Comparison of four page algorithms in recall up to a fixed column position while sweeping the row...
