ABSTRACT
Sentiment analysis is the emerging technique by which one can extract information from vast amount of data dispersed in web documents to improve knowledge management, business intelligence, marketing, sales, etc. This can be used to determine

Karan Chawla et.al [2] proposed a method for sentiment analysis on tweets having conjunctions, connectives, modals and conditionals using discourse relations for polarity detection of tweets. Xiaowen Ding et. al [3] built Opinion Observer, a linguistic rule based system, which was able to detect the polarity of opinions context based and with the use of opinion aggregation function. Damien Poirier et.al [4] developed a model for opinion analysis on movie reviews using machine learning techniques and NLP techniques by building the dictionaries. Guang Qiu [5] et. al proposed a method to extract new sentiment words from sentences and assigned polarity for them using double propagation …show more content…
The sentences where the use of the conjunction or the presence of a double negative has a direct impact on the overall sentiment of the review are identified.
3.2 POS Tagging
In this step, the sentences in the data set collection are tokenized using the POS tagger of Stanford [15]. During this process, a part of speech such as noun, verb, adverb, adjective, conjunctions, negations and the like are assigned to every word in the sentences. It has been made sure that the conjunctions or negatives present in the sentences are tagged correctly using General Inquirer’s word dictionary [14].
3.3 Sentiment Detection
Sentiments are detected for each word using General Inquirer as positive, negative, strong, weak, pleasure, pain and feel.
A conjunction is a word that is used to link words, phrases, or clauses. It is often used to express the relationship between two clauses or phrases in a sentence. A double negative always renders a positive effect i.e. not dislike means like. Conjunctions and double negations have the capability to completely invert the polarity or sentiment of the
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
If a customer is browsing some products on their mobile phones, then the target should be to serve the customer with required pictures, price as well as description about the product. This will help in providing customers with better shopping experience. With the amount of information digitally available to customers on the internet, they can take a decent amount of time to make a purchase online. An effective way to increase the sales online is to have the website with different sections for companies reviews, how to
Moreno, Kelleher, and Pumper (2013) evaluated depression symptoms using social media website by developing depression codebook. This codebook can be used and expanded in future for different disorder cases such as anxiety. They also investigated suicide protocol in this paper (Moreno et al., 2013). De Choudhury, Counts, and Horvitz (2013) also used social media as measurement tool of depression in population. They used crowdsourcing technique to collect data and developed SVM classifier to predict depressive tweets with the accuracy of 73% and along with this geographical analysis of tweets were performed (De Choudhury, Counts, et al., 2013).
Doublethink is simultaneously holding two contradicting opinions at one time. This is a real life situation in which Winston and the reader encounter doublethink without realizing it on the surface level. Winston knows deep down how he really feels and what life could be like in his dream state, while Winston is forced to act a certain way and believe certain things in the real world. Having two contradicting beliefs, while knowing one is the better belief and choosing not to believe it for the benefit of the Party is the exact definition of

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”
nTi’Ana Woods Gary Pegoda ENGL1301 12/16/2014 Essay #1 In the essays “Just Walk on By” and “Blobs” they both give examples of how people react to certain situations or things. For instance, Patricia Brady tells us the affects that the “blobs” had on the community while Brent Staples uses stories and descriptions in “Just Walk on By”. Even though both authors intent to use examples was to persuade their audience, they did so in different ways.
However, other constraints can be set as well, e.g., the part-of-speech tag of a specific token in the expression itself or before or after the temporal expression. For the normalization, it use normalization resources containing mappings between an expression and its value in standard format. Furthermore, linguistic clues are applied to normalize ambiguous expressions. For example, the tense of a sentence may indicate the temporal relation between an expression and its reference time.
Ever since the feisty assistant district attorney, Rebecca Jennings, entered the Cedar Cove landscape near the end of the show’s second season, I was captivated by the actress who breathed life into her. While I often found myself rolling my eyes disdainfully at the audacious Miss Jennings and once in while yelling out in frustration at her antics, the way in which the actress Cindy Busby depicted her added coveted drama and offbeat humor to the story. Furthermore, when she roomed with two other girls during season three, she was typically the prominent one due to her characteristic pessimism, her workaholic tendencies, and her pragmatic articulation. Recently, I had the opportunity to catch up with Cindy, and she granted me an especially
With the rapid-development of technology and economy, digital world endow people ability to obtain much more information than before.

Social Media Analytics and features It is the process of applying data (both structures as well as unstructured) from social media sites such as twitter, facebook, Google+ and other such sites for better understanding of customer attitude and behavior. It also serve as an effective tool for business and market research and ultimately for business decision making. The large availability of user-generated data and the links between users leads to the dispersion of useful information, opinions and sentiment as well as emergent issues and trends (Leskovec 2011; Agrawal et al. 2011; Nagarajan et al. 2011) and is referred to as ‘Social Media Analytics’.
When scrolling through social media it is important that one only feed into some of the things that are put out into the world. People have so many opinions, and loosely throw them around as facts. We, as people have to learn to differentiate between facts and opinions because social media can contain a lot of biased information. From the few things that I learned from social media, I tried to apply them to my life. On social media there are a lot of rumors thrown around, and many people have opinions.
In chapter 1, the main concept of text summarization and word sense disambiguation is introduced. Before starting Text summarization, first we, need to know that what a summary is. A summary can be defined as a non redundant text which gives important information of the original text, and is extracted from one or more sentences. We can say text summarization is the unique way, where a computer summarizes a text. A text is entered into the computer and a summarized text is returned as an output, which is a non redundant form of the original text.
