Information Visualization

The Library uses data visualization to illustrate publishing patterns at Chalmers.

To visualize scholarly publishing patterns we analyze keywords, geographic location of authors, and references in databases such as Web of Science or Scopus. Different types of network graphs and geographic maps are created to illustrate research focus, field structures, and overviews of research collaborations. The visualizations below exemplify some of the techniques we use.



Explore the interactive visualization.

The above image demonstrates which journals researchers at Chalmers cited 2011-2012. The idea behind this visualization is to offer an overview of which journals are used and how these journals are connected to each other.

Every circle in the network represents a journal and a link between two journals indicates that they have been cited in the same publication at least once. If a group of journals appear frequently in the same reference lists they are considered to be in the same field of study and creates a cluster. Each cluster has its own color and represents a potential subject within the network.  

The size of the circle is determined by the centrality of the journal within the network. Two of the most central journals are Science and Nature, which are often cited by researchers at Chalmers.



Which are the most frequent keywords used in publications produced by a research group? The colors in the graph represent keywords which are closely related and the size of the circles the centrality of the keyword in the network. Examples of central words in this network are spectroscopy, kinetics, proteins and DNA. It is our attempt to show the composition and depth of the research focus within a research group.



A way to analyze research collaborations is to study co-authorship. Every red circle on the map represents a university, institute, or company researchers at Chalmers have co-authored at least one publication with during 2011. The size of the circle is determined by the number of co-authorships.

What types of services can the library provide?

We deliver different types of reports based on scientific output and scientometric data which are usually used in the monitoring and assessment of the research activity of departments and Areas of Advance at Chalmers. Time permitting, we can also assist with other matters. When it comes to scientometric analyses at individual level, it is mandatory to provide relevant researcher ID, such as ResearcherID (Web of Science), Scopus Author Identifier (Scopus), ORCID, Google Scholar Profile (Google). You are welcome to get in touch with us, if you are keen to get a better understanding of bibliometrics, or get advice on publishing strategies.
