Sentiment Analysis is the process of determining whether a text or a document is positive,negative or neutral. Sentiment Analysis is a process which classifies documents according to the opinions and emotions expressed by the user. Judging a document’s orientation as positive or negative is a common two-class problem, which is also known as sentiment orientation analysis in text classification.

MITCOE, Department of Computer Engineering, Pune 2015-16 2 Sentimental Analysis and Emotion Recognition Chapter 2 LITERATURE SURVEY Following are the list of paper /journal/books which are helpful for us to go through this topic. Table 2.1: Literature Survey MITCOE, Department of Computer Engineering, Pune 2015-16 3 Sentimental Analysis and Emotion Recognition Chapter 3 Classification Levels Sentiment Analysis is the computational study of peoples opinions, attitudes and emotion towards an entity. The entity can represent individuals, events or topics. Sentiment Analysis identifies sentiments expressed in a text and then analyze it. Therefore, the target of SA is to find opinions, identify the sentiments they express, and then classify their polarity as shown in Fig. 1. There are three main classification levels in SA: document-level, sentence-level, and aspectlevel SA. Document-Level: Document-level SA aims to classify an opinion document as expressing a positive or negative opinion or sentiment. It considers the whole document a basic information unit (talking about one topic). Sentence-Level: Sentence-level SA aims to classify sentiment expressed in each sentence.

The first step is to identify the entities and their aspects. The opinion holders can give different opinions for different aspects of the same entity like this sentence The voice quality of this phone is not good, but the battery life is long. MITCOE, Department of Computer Engineering, Pune 2015-16 5 Sentimental Analysis and Emotion Recognition 3.1 Methodology Text Classification Problem Definition: We have a set of training records D = X1, X2, . . ., Xn where each record is labeled to a class. The classification model is related to the features in the underlying record to one of the class labels. Then for a given instance of unknown class, the model is used to predict a class label for it. The hard classification problem is when only one label is assigned to an instance. The soft classification problem is when a probabilistic value of labels is assigned to an instance. Sentiment Classification techniques can be roughly divided into machine learning approach, lexicon based approach and hybrid approach. Machine Learning Approach(ML): Applies the famous Machine Learning algorithms and uses linguistic
The consequences also show that the term classification can be effectively approximated by the proposed clustering method. The proposed methodology is reasonable and robust. This paper demonstrates the new models totally tested and prove the results statistically significant. The paper also proves that the use of unrelated opinion is considerable for improving the performance of relevance feature discovery models. A promising methodology for developing effective text mining models for RFD discovery based on both positive and negative

Anyone can read a history textbook assigned in class and understand the events in their minds, but understanding the emotion of the people who were there at the events are lost in blank monotone text. Being able to recite events dryly from your textbook is not knowing one’s history. In order to fully understand history, you have to be able to understand every aspect of the events. Every emotion, thought, and desire of the people who were there as the history was made. In order to tell history, you need to attach emotion to the words being expressed so that the reader can fully understand what happened.
In July of 1848, New York’s Seneca Falls was the site of a two-day convention that has transformed the way many Americans viewed the historical mistreatment of women in the 1900s. Elizabeth Stanton had organized an unprecedented women’s rights meeting with about 300 participants – of both men and women – to protest the treatment of women in social, economic, political, and religious life. Authored by Stanton, the Declaration of Sentiments and is one of the major documents to come out the convention. The document explicitly follows the format of its model, the United States Declaration of Independence, but instead of justifications for American settlers to rebel against their colonial management, it details the “injuries and usurpations”

Levels Sentences were scored as Level 2 (Parts 1 and 2) equaled 2 out of 14 and Level 1(Parts 1 and 2) resulted in a score of 10 out of 14. 9. Mirabella’s scores in questions, negatives, phrases and clauses were very low. This shows an inconsistency with the analysis of the ROL

A challenge of writing a rhetorical analysis is writing a thesis statement. By writing the thesis, you have to pick whether you agree or disagree with the topic, to say whether the author’s paper
It is believed that emotional appeal can be the most common and effective rhetorical appeal used in advertising. Authors, Tapan K. Panda and Kamalesh Mishra, elaborated on this in an article titled “Does Emotional Appeal Work in Advertising? the Rationality Behind Using Emotional Appeal to Create Favorable Brand Attitude”. They both noted that, “ad-evoked feelings have direct influence on attitudes towards the advertised brand and purchase intention”. By this, the authors are saying that with the help of emotional appeals the ad can directly elicit a certain perception that the audience may now have of the ad.

Similarly word summarization is also just like a text summarization in which we will give the text as a paragraph and from that text we can find the word summary using Word Sense Disambiguation technique. 1.3 Word sense disambiguation Word Sense Disambiguation is a challenging technique in Natural Language Processing. There are some words in the natural languages which can cause ambiguity about the sense of the word. Those words are called polysemous words.
