A method of content grouping according to a corresponding text comprising the steps of:
- reading from a content list file for a plurality of content groups;
- extracting a key phrase set for each content group;
- determining a set of unique key phrases and a set of non-unique key phrases from each group;
- determining, for each content group, a unique score and a non-unique score;
- determining a unique threshold and a non-unique threshold;
- and
- selecting a content group according to a comparison between the scores and the thresholds comprising,
- comparing the unique score to the unique threshold and selecting a content group including the unique score upon determining the unique score to be in accordance with the unique threshold,
- comparing the non-unique score to the non-unique threshold upon determining that the unique score is not in accordance with the unique threshold, and selecting a content group including the non-unique score upon determining the non-unique score to be in accordance with the non-unique threshold, and
- creating a new content group upon determining that neither score to be in accordance with its corresponding threshold.
