Abstract(s)
Public digital displays could greatly benefit from
the ability to dynamically select from the Internet content
items that would be strongly related with the place where each
display is installed. Generically, this is similar to the type of
problem addressed by recommender systems. However, the
usage context of a public display raises specific challenges that
may limit the applicability of existing recommender systems.
In this paper, we explore the creation of a recommender
system for public situated displays that is able to autonomously
select relevant content from Internet sources using keywords
as input. This type of recommender system should enable
public displays to become devices for Internet information
delivery in public spaces, while also making them more
situated in the social settings in which they are installed. We
have created a recommender system based on these principles
and we have conducted two studies to evaluate the perceived
performance of the system. The results have shown that
keywords can be very effective in driving user-generated
content, but they often need to be complemented with
contextual information that disambiguates their semantics.
