Expanded citations and projections of concepts

Abstract

In our recent paper, we proposed a new kind of citations, called the expanded citations, which link scientific papers and concepts from them. The expanded citations are represented in RDF and can be processed by machines. In this paper, we use the expanded citations to introduce projections of concepts which can be useful in searching for publications. The analysis of the projections and their time evolution gives a knowledge about the role and the significance of the concept in a given domain.
