Hello,
After reading bulk of good quality papers in the field of RE when I have tried to make a survey of approaches followed by the authors I come to a conclusion that if we broadly classify all of them they all directly or indirectly reaching to the classification boundary of
1. manually(checklist based, scenario based, questionnaires, etc- are these goal oriented?)
2. knowledge based(ontology, - are these Aspect-Oriented?)
3. machine learning(supervised, unsupervised, - are these pattern based ?)
Am I correct? or still WE can make it more in-depth tree structure like.. Please provide depth knowledge for this.
Hopefully waiting for reply....
Thanks
