Text summarization with limited number of words I am reviewing summarization techniques and haven't (yet) found an approach to limit the length of a summary. So for example a summarization function that gives me a summary that is &lt; 500 words.

Can you point me in the right direction? Are there approaches/implementations out there that try to solve this challenge?

Appreciate your replies!
You sure can,
for example in latent semantic analysis you can fixate number of topics (which is actually size of the decomposition matrix) beforehand.
