Clustering Categorical Data

if i want to cluster categorical data , then i need to use k-mode which called in knime as
k-medoids , how i can calculate the distance or (dissimilarities ) between the rows of categorical data using knime.

See example. Labels have frequencies.


please ,clear up , how can i measure distance between (categorical data ) not numerical data

i mean ,all my columns are categorical so how can i do clustering by kmedoids in knime

You need assign numbers/distance to categories. It would be helpful if you provide your data example and formulate specific of your research.
