Abstract:
Research fronts are the forefront of a scientific field Timely identifying
emerging trends and abrupt changes in scientific literature is not only
beneficial for users of digital libraries, but also instrumental for users
to trace the movement of a research front. A research front can be seen as a
dynamic and transient mapping from the state of the art to its immediate
prior art - the intellectual base. Citation and co-citation analysis
primarily focuses on the structure and dynamics of the intellectual base,
information retrieval and related research mainly focuses on intrinsic
properties of text documents. In this article, we describe a novel approach
that enables us to detect and visualize the transient relationship over
time. Temporal associations between content words connected to a surge of
interest in scientific papers and high-impact articles in the intellectual
base are identified and visualized as a time-variant network. We apply the
approach to the detection of thematic changes over time in information
visualization and research in terrorism.
