In this model, we first use the probabilistic latent semantic analysis to extract the seed emotion words from the Wikipedia and the training corpus. Then features are extracted from these seed emotion words, which are the input of the maximum entropy model for training the maximum entropy model....

In this paper, we will discuss the extraction of sentiment from a famous microblogging website, Twitter where the user posts their views and opinion. We have done sentiment analysis on tweets which help to provide some prediction on business intelligence. We use Hadoop Framework for processing ...
Sentiment analysis is a technique used for mining data, viewing, evaluating, or analyzing a sentence to predict its emotion using Natural Language Processing. It is done to gain an impartial understanding of the writer's viewpoint towards any particular topic. In this paper, sentiment analysis of...
However, this kind of method has strong subjectivity and low accuracy, and there is no mature sentiment analysis algorithm for the linguistic characteristics of the Danmaku. In order to solve these problems, we propose a sentiment analysis algorithm of Danmaku based on the construction of a mixed...
