Q:

Topic Modelling - Assign human readable labels to topic

I want to assign human readable labels to the results of my topic modelling.
Is there any software library or data set that I can use that takes these key words as an input, and returns a title to describe the topic.
Example:
Input:   ["Church","Priest","God","Prayer"]
Output:  "Religion"
Note: I want automatic label creation - Not manual like others have asked before.

A:

See this paper by Jey Han Lau. He describes how to automatically generate labels using different sources and features.

We generate a set of label candidates
  from the top-ranking topic terms, titles of Wikipedia
  articles containing the top-ranking topic terms, and
  also a filtered set of sub-phrases extracted from the
  Wikipedia article titles. We rank the label candidates
  using a combination of association measures, lexical
  features and an Information Retrieval feature.
