Abstract


Sentiment  analysis  is  one  of  the  key challenges  for  mining  online  user  generated content.  In  this  work,  we  focus  on  customer reviews  which  are  an  important  form  of opinionated  content.  The  goal  is  to  identify each  sentence’s  semantic  orientation  (e.g. positive or negative) of a review. Traditional sentiment classification methods often involve substantial  human  efforts,  e.g.  lexicon construction,  feature  engineering.  In  recent years,  deep  learning  has  emerged  as  an effective  means  for  solving  sentiment classification  problems.  A  neural  network intrinsically  learns  a  useful  representation automatically  without  human  efforts. However, the success of deep learning highly relies on the availability of large-scale training data.  In this  paper, we  propose  a novel  deep learning  framework  for  review  sentiment classification  which  employs  prevalently available ratings as weak supervision signals. The framework consists of two steps: (1) learn a high level representation (embedding space) which  captures  the  general  sentiment distribution  of  sentences  through  rating information;  (2)  add  a  classification  layer  on top  of  the  embedding  layer  and  use  labeled sentences  for  supervised  fine-tuning. Experiments  on  review  data  obtained from Amazon show the efficacy of our method and its superiority over baseline methods.
