Visualization

The visualization of annotated data is of increasing importance as the amount of annotated text increases. The CATMA Visualize module allows you to generate distribution charts of chosen results of your analyses. A graphical representation shows the distribution of the words, phrases, or tags of interest in your text. It is also possible to combine different results into one graph, or to show different graphs in one chart. In providing these features, Visualize greatly facilitates the evaluation of analysis results, considering that particularly an adequate impression of distributional aspects cannot easily be achieved otherwise.

In this example we’ve compared the use of the word “Alte” in three textes – on the left, across the novella cycle “Unterhaltungen deutscher Ausgewanderten” published by Goethe in 1795, next to it in two of the constituent individual novellas. The graph shows us how often the search term is used in every 10% section of the respective text:

Another visualization offered by Visualize is the “DoubleTree.” This is a keyword-in-context visualization through which you can explore the contexts of a keyword along the edges of a double-sided tree:

CATMA will also incorporate new visualization types emerging from the 3DH project, which are intended especially for humanities data.
