===== Lesson 7: Two-attribute interrelationship frequency distribution =====

The KonText interface allows you to view the interrelations of two selected attributes (positional and structural). This property is described in detail in the general [[https://wiki.korpus.cz/doku.php/en:manualy:kontext:frekvence#two-attribute_interrelationship_frequency_distribution|KonText manual]].

To demonstrate using the OBC, we can look at the speakers who used the word //bloody// in the proceedings; specifically, their gender and their role at the court. To view the interrelation between these two attributes, a standard concordance needs to be created.

Make sure you have selected the OBC and using the basic query type, search for the word //bloody//. Click on //Frequency// in the top bar menu and select //Custom//. In the box, select //Two-attribute interrelationship//. Here you can adjust the minimal frequency value or percentile – to include all occurrences, select //absolute frequency// and type in ''1''. In the first row, select the attribute //utterance.speaker_sex//, while in the second row, select //utterance.speaker_role//. When you are satisfied with your selection, click on the //Make frequency list// button.

You will be presented with a table of results summarizing the number of occurrences within each category. You may switch the view mode between table and list of pairs, and you can switch the rows and columns to find which is more suitable. For advanced users, there are several additional options for specifying the data parameters and viewing, such as setting the confidence interval, row and column sorting etc.

You can click on the individual cells to view the information in detail; you may also view the filtered concordance, which will include only the occurrences in accordance to the specified attributes.

You can proceed now to [[en:obc:collocations|the last lesson]] of this course.
