What is the Code Co-Occurrence view?

The Code Co-Occurrence view shows the frequencies of co-occurrence in a multitude of ways, such as a matrix, Sankey diagram, or force-directed graph.

The aim is to relate codes to each other that have been applied either to the same quotations or to overlapping quotations. You can find out which topics are mentioned together or are in proximity to each other. Thus, the results depend on how you have coded the data.

How do I create a Code Co-Occurrence view?

Code Co-Occurrence is one of the views available to you in ATLAS.ti Web. All your views are accessible by clicking on the bar chart icon in the left-hand toolbar in your project.

In the top-right corner, click on "+ New View" and select Code Co-Occurrence from the pop-up menu.

This will create a new view, which you can name as desired by clicking on "Untitled Code Co-Occurrence View" in the top-left corner.

You can now create a co-occurrence table by defining the codes that up your rows and columns. Click on "Code" after "Add Row:" to bring up a list of possible codes to analyze. Scroll through the list or enter a search term to find and toggle the relevant codes you want to include in the table. Repeat the same process for codes that represent the columns in your table.

The resulting table will list the frequencies for each pair of codes, or the number of times that both codes are applied to the same data (in which case, they co-occur).

Remember to save your view by clicking on "Save" in the top-right corner. You can also undo any unsaved changes by clicking on the down arrow next to save and clicking on "Discard changes."

Using the Code Co-Occurrence view

Clicking on any cell in the table will bring up the relevant segments of text in which the two selected codes co-occur. The resulting list will show each data segment, the document in which it is located, and any codes or comments already attached to it. From here, you can view the details or add codes or comments to any individual data segment in the list without having to navigate to the relevant document.

Other options

In the top-right corner, the "Remove empty rows/columns" button is useful for removing multiple codes that don't produce any co-occurrences from the analysis.

The "Chart" button allows you to change between vertical and horizontal orientations of the table and list windows.

The Settings button (indicated by the three dots) will bring up a pop-up menu, where you can add a comment to your view, see the latest save information about the view, or delete the view altogether.
