Personalized News Recommendation with Context Trees

Résumé

The proliferation of online news creates a need for filtering interesting articles. Compared to other products, however, recommending news has specific challenges: news preferences are subject to trends, users do not want to see multiple articles with similar content, and frequently we have insufficient information to profile the reader. In this paper, we introduce a class of news recommendation systems based on context trees. They can provide high-quality news recommendations to anonymous visitors based on present browsing behaviour. Using an unbiased testing methodology, we show that they make accurate and novel recommendations, and that they are sufficiently flexible for the challenges of news recommendation.

Système de recommandation
Les systèmes de recommandation sont une forme spécifique de filtrage de l'information (SI) visant à présenter les éléments d'information (films, musique, livres, news, images, pages Web, etc) qui sont susceptibles d'intéresser l'utilisateur. Généralement, un système de recommandation permet de comparer le profil d'un utilisateur à certaines caractéristiques de référence, et cherche à prédire l'« avis » que donnerait un utilisateur.

Fake news website
Fake news websites (also referred to as hoax news websites) are websites on the Internet that deliberately publish fake news—hoaxes, propaganda, and disinformation purporting to be real news—often using social media to drive web traffic and amplify their effect. Unlike news satire, fake news websites deliberately seek to be perceived as legitimate and taken at face value, often for financial or political gain. Such sites have promoted political falsehoods in India, Germany, Indonesia and the Philippines, Sweden, Mexico, Myanmar, and the United States.
