An Enhanced Semantic Layer for Hybrid Recommender Systems

Iván Cantador, Pablo Castells, Alejandro Bellogín
2011 International Journal on Semantic Web and Information Systems (IJSWIS)  
As a proof of concept and evaluation testbed, the approach is evaluated through its implementation in a news recommender system, in which it is tested with real users.  ...  In such scenario, semantic knowledge bases and item annotations are automatically produced from public sources.  ...  Based on this representation approach, and utilising the ontology hierarchy, the authors present a content-based method for filtering items for a given user.  ...

Semantic User Modelling for Personal News Video Retrieval [chapter]

Frank Hopfgartner, Joemon M. Jose
2010 Lecture Notes in Computer Science  
There is a need for personalised news video retrieval due to the explosion of news materials available through broadcast and other channels.  ...  New relevant materials are fetched and presented to the user based on their interests. A user-centred evaluation was conducted and the results show the promise of our approach.  ...  The simplest method is to create a search query based on the content of each cluster and to retrieve stories using this query.  ...

Reputation Metadata for Recommending Personalized e-Learning Resources

Tania Kerkiri, Athanassios Manitsaris, Anastasia Mavridou
2007 Second International Workshop on Semantic Media Adaptation and Personalization (SMAP 2007)  
In this paper a RDF-based e-Learning framework that is based on reputation metadata and educational standards is proposed.  ...  This system exploits reputation and description metadata to augment personalization in e-Learning systems through recommendation methods.  ...  A framework that combines both content-based methods, as well as explicit and implicit ranking, is described in [9] .  ...

A proactive personalised mobile recommendation system using analytic hierarchy process and Bayesian network

Kam Fung Yeung, Yanyan Yang, David Ndzi
2012 Journal of Internet Services and Applications  
The paper also proposes a strategy for using Bayesian networks for recommendation services.  ...  An analytic hierarchy process based multi-criteria ranking (AHP-MCR) approach has been developed and used to rate recommendations in a variety of domains.  ...  One is based on the user's history, which is a content-based method, and the other is based on group history, which is a collaborative filtering method.  ...

An experimental evaluation of ontology-based user profiles

Frank Hopfgartner, Joemon M. Jose
2012 Multimedia tools and applications  
Even though ontologies seem to be a promising technique to improve the retrieval process, hardly any study has been performed to evaluate the use of ontologies over a longer time period to model user interests  ...  In this work we introduce an ontology based video recommender system that exploits implicit relevance feedback to capture users' evolving information needs.  ...  They can be distinguished into two main categories: content-based recommender systems and collaborative filtering systems.  ...

Efficient Information Retrieval System with Higher Priority for User Preference

T.Gnana Janani, M.Siva Kumar
2014 IOSR Journal of Computer Engineering  
The re-ranking is performed by evaluating the weights of the user's clickthrough data.
