But if ties are resolved according to Borda's proposal, and if C can persuade her supporters to leave A and B unranked, then there will be about 50 A-B-C ballots, about 50 B-A-C and 80 truncated to just C. Aand B will each receive about 150 votes, while C receives 160. American uses include: The Borda count has been proposed as a rank aggregation method in information retrieval, in which documents are ranked according to multiple criteria and the resulting rankings are then combined into a composite ranking. Remember, in the modified Borda count, if there were four candidates, but only two were selected, those two would get two and one point rather than four and three points. \(\begin{array}{|l|l|l|l|l|l|l|l|} In the Modified Borda count, any unranked options receive 0 points, the lowest ranked receives 1, the next-lowest receives 2, etc., up to a possible maximum of n points for the highest ranked option if all options are ranked.
