Improving argumentation-based recommender systems through context-adaptable selection criteria

Juan C.L. Teze, Sebastian Gottifredi, Alejandro J. García, Guillermo R. Simari
2015 Expert systems with applications  
In these systems, the role of the comparison criterion used to decide between competing arguments is paramount and the possibility of using the most appropriate for a given domain becomes a central issue  ...  of programming, by the use of conditional expressions, which argument preference criterion has to be used in each particular situation.  ...  We will also introduce a special type of contextual query that will allow to specify how the server should select a criterion for such repository.  ...

Implicit Feedback through User-system Interactions for Defining User Models in Personalized Search

Gabriella Pasi
2014 Procedia Computer Science  
Personalized search is aimed at tailoring the search outcome to the user context. A user profile represents the user interests and preferences that can be captured either explicitly or implicitly.  ...  In particular implicit feedback techniques are applied to the purpose of collecting user interests and preferences via user-system interactions.  ...  needs behind a query, and has given rise to personalized and contextual approaches to search.  ...
