Online user-generated review data generally comes with opinions about products. These reviews are analyzed for sentiments to know 'What people think?' about that product. These reviews also contains emotional values of human being about product and aspect of that product. In this paper by extending Latent Dirichlet Allocation (LDA) method we analyses these reviews for Emotion analysis on the basis of aspects of product. To accomplish this we have to go through two task-aspect detection from reviews and emotion analysis of these aspects. LDA gives general topics mentioned in review and by using keyword based analysis we can obtain specific aspect about product from reviews. By analyzing specific aspect with help of keyword spotting method we can analyze emotions for per-specific aspect from review. By this method we can identify sentiment and overall emotions about specific aspects of product from reviews.
