Collaborative Sorting

We consider the problem of eliciting product preferences for substitute goods from a population of potential consumers. The preferences are measured on an ordinal scale and are elicited by pairwise comparisons of products. Preference elicitation by pairwise comparisons is considered accurate since it often simulates real buying situations. To elicit a respondent's ranking of n products completely Ω(n log n) pairwise comparisons are necessary. These are easily too many comparisons in settings where the incentive for the respondent is not high though he might be willing to answer a few questions truthfully. Here we describe an approach to elicit typical preferences of a population by asking many persons a few questions instead of asking a few people many questions.
