I am building an intelligent QA bot which will answer user provided question. As of now, I have extracted the super-class and sub-class of the question by applying SVM but, unable to find the target variable in the question. For instance,
Question : How far is it from Denver to Aspen ?
here, Super-class = Numeric, Sub-class = distance, Target = Denver to Aspen
Please help with any approach to find target variable. Thank you!
