  A route recommendation system can provide better recommendation if it also
takes collected user reviews into account, e.g. places that generally get
positive reviews may be preferred. However, to classify sentiment, many
classification algorithms existing today suffer in handling small data items
such as short written reviews. In this paper we propose a model for a strongly
relevant route recommendation system that is based on an MDL-based (Minimum
Description Length) sentiment classification and show that such a system is
capable of handling small data items (short user reviews). Another highlight of
the model is the inclusion of a set of boosting factors in the relevance
calculation to improve the relevance in any recommendation system that
implements the model.
