我有一个评论数据集，如：
"Teacher","Subject","Feedback"
"Dr.Reddy","DSP","He has very good subject knowledge. He didn't take all the lectures. He teaches and explains concepts very well."
"Ms. Vibha","OOPS","She is very regular with classes. But she does not teach in an easy way."
是否可以使用任何向量空间模型（Word2Vec，Tf-idf等）从这些数据中提取方面（特征）以及意见词？
