between a and p in the case B.1 is higher than in the
case B.2 because the user needs are specific and the
article information (about this criterion) very general
relative to the user needs. So the article is less
relevant for the user. The following section presents
the conclusion and future work.
5 CONCLUSIONS
In this paper we have presented the adaptation of a
standard VSM recommender system to our specific
method of indexing (e.g. articles and profiles are
semantically defined in the knowledge base via
relations with the domain knowledge already
defined in it). We first presented the context, our
goal, and the existing approaches, then we explained
the architecture in detail. Finally we explained the
specific task of comparison that we adapted to our
case.
