Let's go to the cinema! A movie recommender system for ephemeral groups of users

Guillermo Fernandez, Waldemar Lopez, Fernando Olivera, Bruno Rienzi, Pablo Rodriguez-Bocca
2014 2014 XL Latin American Computing Conference (CLEI)  
In this paper we present a recommendation system for groups of users that go to the cinema.  ...  In these cases, a recommender system for ephemeral groups of users is more suitable than (well-studied) recommender systems for individuals.  ...  One of these is PolyLens [13] (extension of MovieLens), a research project from the Minnesota University that recommended movies for small groups of users.  ...

Improving performance of collaborative recommender system using combination of learning techniques

Nitin Mishra
2019 International Robotics & Automation Journal  
Recommender systems provide personalized information by learning the user's interests from traces of interaction with that user.  ...  For the users of these web sites it becomes increasingly difficult and time consuming to find the information they are looking for.  ...  Oconnor et al. 8 introduced a movie recommender system called PolyLens which recommends the movies to small group of peoples. 10 They combined the individual recommendation of each member of the group  ...

Group Recommender Systems: Combining Individual Models [chapter]

Judith Masthoff
2010 Recommender Systems Handbook  
This chapter shows how a system can recommend to a group of users by aggregating information from individual user models and modelling the users affective state.  ...  It also shows how group recommendation techniques can be applied when recommending to individuals, in particular for solving the cold-start problem and dealing with multiple criteria.  ...  For instance, a recommender system may select television programmes for a group to view or a sequence of songs to listen to, based on models of all group members.  ...

2011 Proceedings of the 29th Annual European Conference on Cognitive Ergonomics - ECCE '11  
Recommender systems provide users with suggestions of artefacts or other users. Group recommender systems facilitate decision making in groups of users who need to make a choice together.  ...  In this paper we introduce a novel approach providing ad-hoc groups of users who want to watch a movie together with shared on-demand recommendations on mobile devices.  ...  ACKNOWLEDGEMENTS We thank the members of the CML. We thank moviepilot GmbH. Part of the work has been funded by the German Research Foundation (DFG GR 2055/2-1).  ...

Towards a group recommender process model for ad-hoc groups and on-demand recommendations

Christoph Beckmann, Tom Gross
2010 Proceedings of the 16th ACM international conference on Supporting group work - GROUP '10  
In this paper we present an approach for group recommendations for movies based on a novel group recommender process model for ad-hoc groups with on-demand recommendations.  ...  Most of the current systems address individual users, support stationary use, and require pre-configuration.  ...  Acknowledgements We thank the members of the CML (esp. Maximilian Schirmer), and moviepilot. Part of the work has been funded by the German Research Foundation (DFG GR 2055/2-1).  ...

2005 Proceedings of the 2005 international ACM SIGGROUP conference on Supporting group work - GROUP '05  
We introduce the use of negative preferences to produce solutions that are acceptable to a group of users.  ...  This technique takes advantage of the fact that discovering what a user does not like can be easier than discovering what the user does like.  ...  ACKNOWLEDGMENTS We thank Allan MacLean and Joe McCarthy for their insightful comments.  ...

More than the sum of its members

2004 Proceedings of the working conference on Advanced visual interfaces - AVI '04  
Systems that recommend items to a group of two or more users raise a number of challenging issues that are so far only partly understood.  ...  This paper identifies four of these issues and points out that they have been dealt with to only a limited extent in the group recommender systems that have been developed so far.  ...  POLYLENS ( [13] ) is a generalization of the MOVIELENS system ( that recommends movies to groups of users.  ...
