6.6 Conclusion
Although there have been several studies of scientific literature access, little has
been published about the use of social metadata to enhance the effectiveness of the
underlying process. From the social perspective, several factors of author's collab-
oration have to be considered: citation, coauthoring, co-citation, bibliographic
coupling, bookmarking, etc. Measuring aspects of social behavior in science is
still challenging. In this chapter, we focused on citation and coauthor analysis as
sources of evidence to fine-tune document relevance and highlighted some implica-
tions of social relation weighting. More precisely, what constitutes strong collabo-
ration is derived from the shared topics of authors through coauthored publications.
Furthermore, social document relevance is impacted by the social importance of the
authors according to their social position in the scientific network. An experimental
case study shows that our model is effective.
However, at this early stage, there is no means for systematically establishing the
right balance between effectiveness and efficiency of a retrieval model of scientific
information from the social perspective. Thus, the future of social information
retrieval research within a scientific community is promising.
