Regarding the thresholds of the clustering phase (Section 3.2), after training the thresholds with the collection S1 of 65 news articles we have concluded: • The first step in the clustering phase, 1(a), performs a good first grouping with threshold relatively high; in this case 6 or 7.
documents in different languages that have more cognates in common than 6 or 7 are grouped into the same cluster.
