Resumen
Nowadays e-commerce websites offer users such a
huge amount of products, which far from facilitating the buying
process, actually make it more difficult. Hence, recommenders,
which learn from users’ preferences, are consolidating as
valuable instruments to enhance the buying process in the 2D
Web. Indeed, 3D virtual environments are an alternative
interface for recommenders. They provide the user with an
immersive 3D social experience, enabling a richer visualisation
and increasing the interaction possibilities with other users and
with the recommender. In this paper, we focus on a novel
framework to tightly integrate interactive recommendation
systems in a 3D virtual environment. Specifically, we propose to
integrate a Collaborative Conversational Recommender (CCR)
in a 3D social virtual world. Our CCR Framework defines three
layers: the user interaction layer (3D Collaborative Space Client),
the communication layer (3D Collaborative Space Server), and
the recommendation layer (Collaborative Conversational
Recommender). Additionally, we evaluate the framework based
on several usability criteria such as learnability, perceived
efficiency and effectiveness. Results demonstrate that users
positively valued the experience.
