Plots a diagram with relationships between words. The lines that link the terms are weighted according to how often the connect together
plot_relationships(df, ..., min.freq = 25, threshold = 0.1)
df | a dataframe with paper results |
---|---|
... | additional parameters |
min.freq | minimum frequency of the words to be plotted |
threshold | correlation threshold |
