Key Words Through Graph Entropy Hierarchical Clustering

October 24, 2012

In the last post I showed how to extract key words from a text through a principle called graph entropy.
Today I’m going to show another application of the graph entropy in order to extract clusters of key words.

The key words of a document depict the main topic of the content, but if the document is big, often, there are many different sub topics related to the main.

In this perspective, a clusters of keywords should make easier for the reader the identification of the key points of a document.
