Subjective Review-based Reputation

The choice of a product or a service is often influenced by its reputation,
which is usually calculated from existing reviews of this product or service.
A review can be either {\em objective}, for instance when referring to concrete
features of a product, or {\em subjective}, for instance when referring to the
feeling of the reviewer about one aspect. Subjective reviews are potentially
biased by the characteristics of the reviewers, and therefore two subjective
reviews should not be treated equally. We propose in this paper a model of
reputation compensating the subjective bias of different categories of
reviewers. We firstly calculate this bias by analyzing the ratio between
reviews coming from different categories, and then we project a subjective
reputation for a given category of reviewer.  We demonstrate the accuracy of
our bias calculation with an experimentation on public reviews for hotels, and
two specific categories of users.
