For a recommender system , sentiment analysis has been proven to be a valuable technique. A recommender system aims to predict the preference to an item of a target user. Mainstream recommender systems work on explicit data set.


For example, collaborative filtering works on the rating matrix, and content-based filtering works on the meta-data of the items. In many social networking services or e-commerce websites, users can provide text review, comment or feedback to the items. These user-generated text provide a rich source of user's sentiment opinions about numerous products and items.

Since these features are broadly mentioned by users in their reviews, they can be seen as the most crucial features that can significantly influence the user's experience on the item, while the meta-data of the item usually provided by the producers instead of consumers may ignore features that are concerned by the users. For different items with common features, a user may give different sentiments. Also, a feature of the same item may receive different sentiments from different users. Users' sentiments on the features can be regarded as a multi-dimensional rating score, reflecting their preference on the items.

The first motivation is the candidate item have numerous common features with the user's preferred items, [58] while the second motivation is that the candidate item receives a high sentiment on its features.

For a preferred item, it is reasonable to believe that items with the same features will have a similar function or utility. So, these items will also likely to be preferred by the user. On the other hand, for a shared feature of two candidate items, other users may give positive sentiment to one of them while give negative sentiment to another. Clearly, the high evaluated item should be recommended to the user.

Based on these two motivations, a combination ranking score of similarity and sentiment rating can be constructed for each candidate item. Except the difficulty of the sentiment analysis itself, applying sentiment analysis on reviews or feedback also face the challenge of spam and biased reviews. One direction of work is focused on evaluating the helpfulness of each review. Besides, a review can be designed to hinder sales of a target product, thus be harmful to the recommender system even it is well written.

Researchers also found that long and short form of user-generated text should be treated differently. An interesting result shows that short form reviews are sometimes more helpful than long form, [60] because it is easier to filter out the noise in a short form text. For the long form text, the growing length of the text does not always bring a proportionate increase of the number of features or sentiments in the text.
