Which of the following words is correct and why?

This helps discriminating/discrimination of objects...

  • This helps to discriminate objects? – Andrew Tobilko Mar 30 '19 at 17:36
  • This helps in the discrimination of objects? (I can't think of any minor rephrasing that would make discriminating sound natural.) – Jason Bassford Mar 30 '19 at 17:39

    This helps with discriminating objects sounds natural to me, @JasonBassford. (Though it potentially has another meaning) – Colin Fine Mar 31 '19 at 0:30

    As commenters note, one or more words need to be inserted to make it a correct sentence. Another possibility: "This helps to discriminate between objects." – Edward Barnard Apr 2 '19 at 17:47

X-ion/X-tion/X-sion/X-ation leans toward meaning the result/effect of an action X. As actions are typically done to achieve results, -ion words are often used to talk about both.

X-ing leans toward meaning the actual action X not necessarily connected to an end or result. You may use this if the action is not expected to be completed, or is being talked about abstractly.

The configuring is the most difficult part.

Here, configuring is probably part of a process that will be repeated over and over. We are talking about configuring abstractly and not an instance of actual configuring which will be expected to be completed.

The configuration is the most difficult part.

Here, configuring is probably something you have to do, and it will be difficult, but you are expected to actually perform it and complete it, resulting in a configuration.
