Citation Map Visualizing citation data in the Web of Science In this brief presentation we’ll be taking a look at the new Citation map feature in the Web of Science. Download the slides for this presentation from the Attachments tab in the Brainshark viewer. July 2008

What is a Citation Map? Graphical display of citation relationships Interactive citation tree Forward and backward citations Up to two generations Organize and color code results Save as an image for use in other software Technical requirements Java is required for your web browser http://www.java.com/en/download/index.jsp Citation map is a way to visualize citation relationships between articles. It is an interactive citation tree that displays both forward and backward citations and can be color coded and organized to easily discover trends in citation activity. The citation map can be then be saved as an image for later use. In order to use Citation Map your browser must support the most current version of Java. Visit the java website to download the latest version.

Web of Science – Citation Map Citation Map is available on all Web of Science full records. This article by the author Hobbs has been cited 15 times and also cited 40 references itself. Click the Citation Map link to go to the Citation Map setup screen. Launch a Citation map from a Web of Science Full Record 3 3

Citation Map Setup The citation map setup page allows you to choose the direction of citations and the number of generations you would like to map. First select ** forward citations, backward citations or both. Next choose ** the number of generations you would like to see. One generation will show the citing and cited articles for your target paper. Extending to two generations will add citing and cited articles for the first generation papers. Click the create ** button to continue.

Citation Map – two forward generations First generation citations Second generation citations Papers are represented on the citation map as nodes. Lines extend from the target paper in a tree structure to show the links between papers. This example citation map shows two forward generations from the target paper written by BF Hobbs. It shows not only the papers that cite Hobbs, but also shows the papers that cite those citing papers, or second generation citations. This Citation Map shows that although Hobbs BF was only cited directly 15 times, there are 133 papers on the map when we also look at the second generation citations. 5 5

Citation Map – one generation This citation map is an example of one generation of both forward and backward citations. When the map is first created, all nodes are the same color and are labeled with the first author’s name. The appearance can be changed ** using the toolbar at the upper left. The node color and text can be changed and nodes can be reordered based on author name, journal title, publication year, document type, subject category, language, country and institution. In this example **, nodes have been labeled and color coded by subject category to reveal which areas of research have a relationship to the target article. A summary of each paper is shown in the ** lower left panel and is also color coded. The directional arrow in the table indicates the direction of the citation. Place a checkmark in the box to the left of a paper to highlight it on the map. Double clicking any paper on the map ** will display a more detailed summary in the panel on the right. Click the link in the title field to move directly to the Web of Science record for the paper.

Full screen view Hide the lower panels by clicking on the ** down arrow in the center of the page. You can now view the Citation Map in full screen view. Reveal the panels again with the ** up arrow.

Quick Change Buttons Use the quick change buttons in the ** 3 animations** upper right corner to quickly reconfigure the map.

Quick Change Buttons Expand the space around the highlighted node Contract the space around the highlighted node Re-center the Citation map on the original paper Create a new citation map The quick change buttons expand or contract the space around the highlighted node, quickly re-center the map or create an entirely new citation map from a highlighted node.

Create additional citation maps Create new citations maps for any node on the map. Find a paper on the map quickly by using the ** checkbox to highlight it **. Use the Manage menu ** to create a new citation map or ** use the quick change button in the upper right corner.

Save as an Image Any map can be saved as an image file for later use. Under the manage menu select Save Citation Map as Image. Be sure that your browser’s Pop-Up blocker is turned off. ** A dialog box will appear – click the link to download the image. ** Select Save to disk to save the image to your computer. By default it will save as a .PNG file, but during the process of saving you can change the file extension to another image type like .GIF or .JPG.
