Sentiment Analysis & Context-Awareness in Recommendation



Sentiment Analysis.

The concept of sentiment analysis (or opinion mining) is defined by Feldman [2013] as the task of finding the opinions of authors about specific entities. The eParticipation platform developed includes a first approach of sentiment analysis with dynamic profiles. Nevertheless, more advanced tools for including sentiment analysis in profile generation, such as data mining, machine learning, and artificial intelligence, should be included to imporve recommendations.


Contextual information could used to improve the prediction accuracy of Recommendeer Systems. The use of context-awareness has been studied by a number of researchers to improve the quality of recommendations. Future work can include additional functionalities to support context-awareness for the SmartParticipation project.
