I am working on a natural language processing data problem and I have selected some keywords from it as features. I want to group them under one heading. But I can't find any method or algorithm to do that? I tried topic modelling using MALLET. It groups similar words into a cluster. I want a heading or subject attached to them.
Is there a way to group similar words under one topic and assign them a title?
There are a number of different features that need to get one topic like picture quality camera selfie resolution that should come under camera. Need something that groups these things I enter words and it gives me the topic.
