Twitter for Sentiment Analysis: When Language Resources are Not Available

Abstract: Affective lexicons are a useful tool for emotion studies as well as for opinion mining and sentiment analysis. Such lexicons contain lists of words annotated with their emotional assessments. There exist a number of affective lexicons for English, Spanish, German and other languages. However, only a few of such resources are available for French. A lot of human efforts are needed to build and extend an affective lexicon. In our research, we propose to use Twitter, the most popular microblogging platform nowadays, to collect a dataset of emotional texts in French. Using the collected dataset, we estimated affective norms of words to construct an affective lexicon, which we use for polarity classification of video game reviews. Experimental results show that our method performs comparably to classic supervised learning methods.

Role of Emoticons for Multidimensional Sentiment Analysis of Twitter

Abstract: Microblogging systems such as Twitter and Facebook have become popular. People can easily post their sentiments to the Internet in real time using such microblogging systems. Twitter is a text-based communication tool. Users cannot use non-verbal communication tools such as gestures and eye contact on Twitter. Users sometimes use emoticons as an alternative non-verbal communication tool to tweet delicate sentiments. In this paper, we propose a method of determining sentiment of a tweet based on the emoticon role. Specifically, we propose the following: (1) compilation of a sentiment lexicon and an emoticon lexicon; (2) emoticon roles can be classified into four types showing "Emphasis", "Assuagement", "Conversion", and "Addition", with roles determined based on a relation between sentiments of sentences and emoticons; and (3) the relation can be formalized using regression analysis in all roles excepting for "Addition".

Word-of-Blog for Movies: A Predictor and an Outcome of Box Office Revenue?

Abstract: Social media has become an important avenue of Word-of-mouth (WOM) and a recent study has found blogging to be an important lead-generation source among social media options. This article examines the dynamic interrelationship between word-of-blog volume and sales by using the movie industry as the research context. By employing the Granger Causality test and modeling the interrelationship through simultaneous equations, the results show that the volume of word-of-blog and box office revenue for movies provide significant causality and explanatory power for each other, supporting word-of-blog volume is both a predictor and an outcome of sales. The results also highlight for retailers the importance of strategically managing word-of-blog to influence consumer purchase decisions and generate revenue as well as the value of the findings for forecasting. Keywords: Word-of-Mouth; Word-of-Blog; Social media; Blogs; E-commerce (ProQuest: ... denotes formulae omitted.) 1. Introduction Word-of-Mouth (WOM) is usually believed to be a credible information source for consumers' purchase decisions [Bynerjee 1992; Brown & Reingen 1987]. The Internet and online communities have brought WOM to an even wider reach at a faster speed. For instance, online WOM can influence people's online purchase via buyers' subjective norm [Cha 2011; Suntompithug & Khamalah 2010] or via seller reputation [Saastamoinen 2009]. Online WOM can take many forms such as online reviews, discussion boards, video sites, blogs, microblogs, social networks, and so on. With the rapid increase in popularity of Web 2.0 technologies and the explosive growth of online social communities, social media, i.e. consumer-generated media and content, have emerged as new channels in which consumers interact and influence each other, as well as channels in which businesses and consumers interact and influence each other. Not only are a huge percentage of consumers and businesses online engaged in social media, but also a very large percentage of consumers discuss the brands and products they love or hate. Such social media are perceived to be transparent, inclusive, authentic, grassroots and consumer-driven [Baker 2009]. The unprecedented openness, velocity (speed) and volume of conversations produced by social media have made them become a vital avenue for transmitting WOM. David Meerman Scott [2008] claims the challenge to marketing "is to harness the amazing power of . . . whatever you call it - viral, buzz, word-of-mouse, or word-of-blog - having other people tell your story drives action. One person sends it to another, then that person sends it to yet another, and on and on." According to the Wikipedia entry for blog [http://en.wikipedia.org/wiki/Blog], "A blog (a contraction of the term "weblog") is a type of website, usually maintained by an individual with regular entries of commentary, descriptions of events, or other material such as graphics or video. Entries are commonly displayed in reverse-chronological order." Based on a survey of 167 executives and business owners mostly from small and medium-sized businesses, a recent study [Walsh 2009] found blogging to be an important lead-generation source among social media options. Blogs have become pervasive and part of people's daily lives. For instance, Technorati [http://technorati.com] has indexed 133 million blog records since 2002. According to Technorati [2008], comScore MediaMetrix [http://www.comscore.com] in August 2008 reported there are 77.7 million unique blog visitors in the US among the total 188.9 million internet audience; eMarketer [http://www.emarketer.com] in May 2008 reported 22.6 million US bloggers in 2007 and 94.1 million US blog readers in 2007; Universal McCann [http://www.umww.com] in March 2008 reported 184 million WW have started a blog, 346 million WW read blogs, and 77% of active Internet users read blogs. In addition, this Technorati report indicated that "Four in five bloggers post brand or product reviews, with 37% posting them frequently. …

InfluenceTracker: Rating the impact of a Twitter account

Abstract: We describe a methodology of rating the influence of a Twitter ac-count in this famous microblogging service. We then evaluate it over real ac-counts, under the belief that influence is not only a matter of quantity (amount of followers), but also a mixture of quality measures that reflect interaction, awareness, and visibility in the social sphere. The authors of this paper have created InfluenceTracker, a publicly available website where anyone can rate and compare the recent activity of any Twitter account.

The enlightenment meets twitter: using social media in the social studies classroom

Abstract: Social media services afford users ways to digitally interact, communicate, and collaborate that were not available just a decade ago. While citizens worldwide use these media for democratic and imaginative purposes, social studies educators, and educators in general, have been slow to explore these technologies that are increasingly a part of the daily lives of K-12 students. Even though many schools still block or filter such sites, some social studies educators have found creative ways to use services like Twitter. We explain how social studies educators can, and have, used the microblogging service Twitter. We then detail an example of a classroom-tested lesson where one of the co-authors utilized the service to craft a dynamic, participatory, and complex lesson that helped his students explore the beliefs of philosophers of the Enlightenment era.
