converting the extracted key phrase candidates into feature vectors;
filtering the feature vectors to remove duplicates using a classifier that was trained on a set of key phrase pairs with manual labels indicating whether two key phrases are duplicates of each other, to produce remaining feature vectors for remaining key phrase candidates; and
assigning scores to the remaining key phrase candidates based upon the remaining feature vectors, wherein a key phrase candidate is the topic, and further wherein the topical authority score assigned to the website is based upon a score in the scores assigned to the key phrase candidate.
