Topic Modelling #4
Description
We are using topic modeling to find out the distribution of topics used by different type of people. Here, the actual use of topics won't matter but we would rather use how varied the topics are i.e. our feature would be variance in topics in a document.
This feature is like, whether the author is concerned and focused about a topic or is perplexed. This is based on intuition like elder people are expected to be more to the point and focused and therefore using lesser no of topics in a given document.
