***** To join INSNA, visit http://www.insna.org ***** Dear All, I am currently doing my master thesis about finding trends in scientific communication. My work is affiliated with Dr. Detlef Schoders Department of Information Systems and Information Management at the University of Cologne (www.wim.uni-koeln.de) and supported by Dr. Kai Fischbach from Cologne and Dr. Peter Gloor from the MIT. We are looking for ways to obtain a large set (approximately 30 years) of data from the Medline database, which for example is accessible through www.ncbi.nlm.nih.gov/entrez and through many other interfaces. The data shall be used to create two different kinds of (dynamic) networks: 1. Coauthorship networks 2. Citation networks In these networks, we want to find trends and trendsetters by applying SNA methods like calculating centrality values and by applying information retrieval methods on the content (article titles and abstracts). Therfore it is vital to get not only article titles and authors but also abstracts and citation data. The current question is how to get the data which is neccessary to create these two networks with emphasis on the problem of getting citation data. Has anyone of you done similar research before and could provide us help on how to obtain the data? Any further suggestions on how to proceed and related work are also welcome.
