A hybrid recommendation system for news in a mobile environment

Abstract

Over the last few years consumption of news articles has shifted more and more from the written versions towards the web. Mobile devices, which became more powerful, with larger screens and connected to the Internet, have had a great influence on this paradigm change. A critical problem associated to online news is related to the fact that the large number of daily articles can be overwhelming to the users. Recommendation services can largely improve the efficiency and accuracy of acquired information. These systems are designed to filter critical news, key events and meaningful items that might be of interest to a reader.In this paper, a news recommendation system in a mobility scenario is presented. The implemented recommendation system combines content-based and georeferenced recommendation techniques. Recommendations are supported by short-term and long-term user profiles created implicitly and considering also the mobile device geolocation. The final recommendation list is obtained by combining recommendations provided by the different recommendation approaches. To evaluate the performance of the solution, a user study was conducted. Results indicate that the quality of the recommendations is acknowledged by the test users. The system was integrated in a mobile application of a Portuguese newspaper (Público) in the context of the project Pglobal.

News recommender system: a review of recent progress, challenges, and opportunities

“…They assumed that user experience is a global phenomenon for all users, so they use one measure for all. For some researchers, it can be measured through accuracy (Nguyen et al 2014;Viana and Soares 2016;Su et al 2016). They demonstrated that higher ratings provide more pleasing and satisfactory experience to the users.…”

“…Both, present a slight increase of publications since 2016 that demonstrates to more advanced methods (Babanejad et al, 2020;Hazrati & Elahi, 2021). Approaches that use temporal features (Muralidhar et al, 2015), movie and mobile solutions (Tewari et al, 2016;Viana & Soares, 2016), collaborative filtering applications (Saranya & Sadasivam, 2017;Wang et al, 2017) or neural networks to solve the cold-start problem (Misztal- In what automated journalism concerns, the most part of the articles focus on exploratory studies (RQ1). Approaches focus on understanding ethical issues and the impact on the working practices of journalists in digital newsrooms (Carlson, 2014;García-Avilés, 2014), on the potentialities and pitfalls for news organizations (S.

“…Methodologies considering user location [21], mobile devices [22][23][24], or social networks [19], have also emerged because of the dissemination of these devices and applications among the population. Besides the academic community proposals, several adaptive commercial news recommending systems, such as Google News and Yahoo!…”
