Title: Filter Bubble: a Dynamic Evaluation over Recommendation Systems

Presenter: Larissa Spinelli

Abstract:

The term filter bubble refers to a narrowed access of information caused by  
personalization. In this work we seek to understand the circumstances under  
which a filter bubble can arise, and its effect on users.
In particular, we look at whether the use of recommender system can affect  
user experience and user opinions in a systematic way.
We consider the user and the user's personalization system as a closed  
loop, and ask what the effects are on both user and the recommender system  
over time.  We define and analyze two metrics  - simplification and  
intensity - to understand those effects over recommendation systems using  
matrix factorization.
The presentation will cover some results and findings of this on-going  
research.
