Gediminas Adomavicius, Ramesh Sankaranarayanan, Shahana Sen, Alexander Tuzhilin
2005 ACM Transactions on Information Systems  
A multidimensional approach to recommender systems is presented that provides recommendations based on various contextual information in addition to the typical information on users and items used in most  ...  To test the proposed approach in practice, a multidimensional application for recommending movies was developed and the combined approach implemented.  ...  Instead of providing the standard recommendation of "top N items to a user," we can now use the available profiling information to provide more targeted recommendations, such as recommending "top 3 action  ...

$$\mathcal {IRORS}$$ IRORS : intelligent recommendation of RSS feeds

Nedia Araibi, Eya Ben Ahmed, Wahiba Karaa Ben Abdessalem
2016 Vietnam Journal of Computer Science  
However, the user is flooded by the amount of such RSS feeds. For that reason, any analysis of RSS feeds seems effortful and complex.  ...  The abundance of information prohibits getting relevant results on online social researches. Thus, RSS feeds appear as monitoring tool of current events according to users preferences.  ...  reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.  ...

A Pre-filtering Approach for Incorporating Contextual Information into Deep Learning Based Recommender Systems

Isam Mashhour Al Jawarneh, Paolo Bellavista, Antonio Corradi, Luca Foschini, Rebecca Montanari, Javier Berrocal, Juan M. Murillo
2020 IEEE Access  
Traditional recommender systems are mostly dependent on a conventional model that is based on user-item-rating interaction without considering contextual information.  ...  However, only few research works have focused on how to effectively and efficiently exploit context metadata in Deep Learning (DL)-based recommendations.  ...  The rationale for selecting this metric is to evaluate the Top-N recommendations and in this case quantifying the times that the top element in the Top-N list matches the target.  ...

Personalized recommendation on dynamic content using predictive bilinear models

Wei Chu, Seung-Taek Park

Semantics-Aware Autoencoder

Vito Bellini, Tommaso Di Noia, Eugenio Di Sciascio, Angelo Schiavone
2019 IEEE Access  
Accuracy in the recommendation is no more enough since users are also expecting a useful explanation for the suggested items. Users, on the other hand, want to know why.  ...  They help users to find what they are looking for by suggesting relevant items leveraging their past preferences.  ...  We use then ratings from Equation ( 5 ) to provide top-N recommendation for each user. B.  ...

Exploring Contextual Paradigms in Context-Aware Recommendations

Conor Morgan, Iulia Paun, Nikos Ntarmos
2020 2020 IEEE International Conference on Big Data (Big Data)  
Traditional recommendation systems utilise past users' preferences to predict unknown ratings and recommend unseen items.  ...  In this work, we explore these three ways of incorporating context in the recommendation pipeline, and compare them on context-aware datasets with different characteristics.  ...  Each user will have a predicted top-k list and an actual top-k list based off their actual ratings.  ...
