the seed list. An original approach is proposed in
(Ghose et al., 2007) where the opinion is inferred by
observing the effect of user comments found in a rep-
utation system on the prices of the products sold.
7 CONCLUSIONS
Forum Recommender Systems may use knowledge
and techniques from various research fields such as
the generation of recommendations in social net-
works, the presence of influence, the trust propaga-
tion. Although much work has been done in identify-
ing and incorporating these notions in other types of
social media, there does not exist an in-depth study
of how they can be incorporated in the context of
forums. This paper provides the researchers with a
generic framework and outlines the main challenges
and open areas that still need to be explored.
