Citation Map

A Citation Map is a graphical representation that shows the citation relationships (cited references and citing articles) between a paper and other papers using various visualization tools and techniques. A paper can be an article, proceedings paper, book, or other document type as defined by the product database that you are using.

Using citation mapping, you can analyze which researchers are citing your papers. You can also choose to organize and color code the results by author, year, journal title, subject category, and more.

You can also set up a graphical representation of the papers that you have cited in a published work. You can then choose to organize and color code the results by author, year, journal title, subject category, and more.

Creating a Citation Map

From a Full Record page, click the Citation Map link to go to the Citation Map start page where you can begin to create your Citation Map.

1. Select a direction.

Forward Only: View records that cite the selected target (focus) record whose name appears in the title bar at the top of the page.

Backward Only: View records that the target record cites.

Forward and Backward: View both forward and backward records.

2. Select a generation.

First Generation - Records that cite or are cited by the target record are first generation. The default generation is set at 1.

Second Generation - Records citing records that cite the target record and records cited by records cited by the targeted record are second generation.

3. Click the Create button to create your Citation Map.

The Target Record

After you create your Citation Map, the target record is shown in the middle of the Citation Map panel. To the right of the target record are papers that cite the original paper (citing articles). This is the forward view. To the left of the target record are papers that are cited by the target record (cited references). This is the backward view.

Citation Map Panels

The Citation Map is generated and displayed in a three-panel window.

  • The top panel (Citation Map) is an interactive graphical presentation of the Citation Map consisting of a citation tree of nodes (records) showing their citation relationships.

  • The lower left panel (Results Set) displays a summary of cited and citing records in the Citation Map along with the Primary Author, Journal Name, and Article Title.

  • The lower right panel (Record View) displays the Full Record of the target record.

  • Above the Citation Map are menus and options that allow to manage and control of the appearance of the Citation Map.

Navigating the Panels

You can move the nodes around (including the target node) by clicking and dragging them using your left mouse key. This feature allows you to see parts of the map that are on the edge of the panel. This dragging action also brings the centered-map section into view so you can see the individual nodes more clearly.

By hovering your cursor on any node, you can view bibliographic information about that paper such as article title, source title, author, and much more. If your subscription includes the Chinese Science Citation Database, then some bibliographic data may display in both English and Chinese.

Be aware that if there is no article title, the system will display an "article title not available" message.  You will see this message mostly for cited references in which the record is not indexed in any of our citation indexes such as Web of Science Core Collection.

A white expand / collapse button displays in the bottom-right corner of the target node if there are citations for that record. Click to expand or collapse the display. You can also find these buttons on the back and fwd nodes.

About Citing and Cited Records

Keep in mind the following when analyzing citations.

Forward Only citations (citing articles) come from source records in the product.

Backward Only citations (cited references) come from source records and non-source cited articles.

index

More About Generations

A paper's cited references and citing articles are referred to as the first generation of cited and citing papers. Each of those cited papers may have cited references of their own and each of the citing articles may have citing articles of its own. This second level of papers is referred to as the second generation.

Please be aware ... Nodes in a Backward Only, second generation Citation Map end at the first generation if they are not source records in the product or if they are inaccurate variations on a source record.

Please note ... Nodes in a Forward Only, second generation Citation Map end at the first generation if those records do not have citing articles.

Printing Tips

When trying to print a Citation Map with a large number of citations (forward, backward, or both), we suggest:

  1. Click the close Close Results Set and Record View panels image control icon to hide the Results Set and Record View panels to provide more real estate for the Citation Map.

  2. Use your left mouse key to move the nodes around to expand different views of the Citation Map.

  3. Click the collapse button on the back node to print only the forward view.

  4. Click the collapse button on the fwd node to print only the backward view.

index

Caution

You may encounter performance problems if you try to create a Citation Map for a record that has a large number of cited references and citing articles. This may be particularly true if you select the Second Generation option in both the Forward and Backward direction. If you encounter performance problems, we suggest that you revise your search and select only the Forward or Backward direction, but not both.
