I used Extract Topics from Data (LDA). The result makes sense. However, I want to see how some topics fade away or become more popular over the years. Please can you help? Thank you.

    Hi,

    why don't you chart something like avg(congidence(topic_1)) over time?

    Thank you, Martin. But what 'congidence' refer to? I can't find this operator.
