2. The computer implemented method of claim 1 , wherein generating the score for the entry from the plurality of entries comprises: aligning terms in the entry with terms in the additional entry; comparing each term in the entry with a corresponding aligned term in the additional entry; determining a cost associated with each term in the entry based at least in part on a difference between the term in the entry and the corresponding aligned term in the additional entry; generating a modified cost for one or more terms identified as trending terms by discounting a cost associated with a term identified as a trending term; and generating the score based at least in part on the costs and the modified costs.
