- Abstract: News recommendation is a core technique used by many online news platforms.
Recommending high-quality news to users is important for keeping good user
experiences and news platforms' reputations. However, existing news
recommendation methods mainly aim to optimize news clicks while ignoring the
quality of news they recommended, which may lead to recommending news with
uninformative content or even clickbaits. In this paper, we propose a
quality-aware news recommendation method named QualityRec that can effectively
improve the quality of recommended news. In our approach, we first propose an
effective news quality evaluation method based on the distributions of users'
reading dwell time on news. Next, we propose to incorporate news quality
information into user interest modeling by designing a content-quality
attention network to select clicked news based on both news semantics and
qualities. We further train the recommendation model with an auxiliary news
quality prediction task to learn quality-aware recommendation model, and we add
a recommendation quality regularization loss to encourage the model to
recommend higher-quality news. Extensive experiments on two real-world datasets
show that QualityRec can effectively improve the overall quality of recommended
news and reduce the recommendation of low-quality news, with even slightly
better recommendation accuracy.

We build a novel dataset, called NewsQuote, consisting of 23,571 quote-speaker pairs sourced from a collection of news articles.
We formulate the recommendation task as the retrieval of experts based on their likelihood of being associated with a given query.
Our results show that employing an in-context learning based LLM ranker and a multi-layer ranking-based filter significantly improve both the predictive quality and behavioural quality of the recommender system.

We build on contextual bandits recommendation strategies which naturally address the exploitation-exploration trade-off.
We use deep learning representations for users and news, and generalise the neural upper confidence bound (UCB) policies to generalised additive UCB and bilinear UCB.

This work is inspired by the fact that users make their click decisions mostly based on the visual impression they perceive when browsing news.
We propose to capture such visual impression information with visual-semantic modeling for news recommendation.
In addition, we inspect the impression from a global view and take structural information, such as the arrangement of different fields and spatial position of different words on the impression.
