Automated text analytics to identify related ideas

It would be a huge timesaver if Aha could automatically suggest common groupings for new ideas, especially when there is a large scale of ideas submitted. For example, there many be multiple ideas submitted all related to a common need, however each is described a bit differently. The existing "Related Ideas" section seen by the idea submitter is really great, giving this capability to the workspace owner would be amazing. Ideally the text analytics could map ideas to the pre-defined categories (categorization) and also identify new categories which may not be known yet (clustering). I'm happy to engage further on the need!
