The problem of rating aspects from textual reviews is an important task in this field. In this paper we propose a new method for rating product aspects as well as for identifying important aspects in general. Our proposed model is based on the least square method. The experiments are carried out on the data collected from hotel services with the aspects including the cleanliness, location, service, room, and value. We have obtained more accurate results than some well-known previous studies. date: 2015-09 type: Conference or Workshop Item type: PeerReviewed identifier: Pham, Duc Hong and Le, Anh Cuong and Le, Thi Kim Chung (2015) A Least Square based Model for Rating Aspects and Identifying Important Aspects on Review Text Data.
