In particular, the advent of social networking platforms makes this communication trend ever more prevalent. User-generated contents from the social networking services become a giant source of information which can be useful for organizations or businesses in the sense that users are regarded as clients or potential clients for businesses or members of organizations. The exploitation of user-generated texts can help to identify their sentiments or intentions, or reduce the effort of agents in businesses or organizations who are responsible for gathering or receiving information on social networking services. In this thesis, we realized a study about semantic analysis and representation for natural language texts in various formats such discourses, utterances, and conversations from interactive communication on the social networking platforms. With the purpose of finding an effective way to analyze and represent semantics of natu- ral language utterances, we examine and discuss various approaches ranging from the using rule-based methods to current deep neural network approaches. Deep learning approaches require massive amounts of data, in our case: natural language utterance and their meaning representations—to leverage this requirement we employ an empirical approach and propose a general architecture for a meaning representation framework for the French language. First of all, for each sequence of input texts, we analyze each word morphologically and syntactically using the formalism of dependency syntax, and this constitutes the first module of our architecture. During this step, we explore lemmas, part-of-speech tags and dependencies as features of words. Then, a bridge between syntax and semantic is built based on the formalism of Combi- natory Categorial Grammars (CCG), which provides a transparent syntax-semantic interface. This constitutes the second module of our architecture. The morphological and syntactic data obtained from the previous module are employed as input in the process of extraction of a CCG derivation tree. More precisely, this process consists of two stages: the first one is the task of the assignment of lexical categories to each word depending on its position and its relationship with other words in the sentence; the second one focuses on the binarization of dependency trees. The parsing of CCG derivation trees is realized on binary trees by applying the combinatory rules defined in CCG theory. Finally, we construct a meaning representation for utterances based on the Discourse Rep- resentation Theory (DRT) which is built from Discourse Representation Structure (DRS) and the Boxer tool by Johan Bos. This constitutes the last module of our architecture. Data such as CCG derivation trees obtained by the previous module are used as input for this module, together with additional information such as chunks and entities. The transformation of in- put CCG derivation trees into the DRS format is able to process linguistic phenomena such as anaphoras, coreferences and others. As output, we obtain data either in FOL or in the DRS boxing format. By implementing our architecture we have built a French CCG corpus based on the French Tree Bank corpus (FTB). Furthermore, we have proven efficiency of the use of embedding vi features from lemmas, POS tags and dependency relations in order to improve the accuracy of the CCG supertagging task using deep neural networks. vii Résumé IMT Atlantique Département Informatique Analyse de la structure de représentation du discours pour le français par Ngoc Luyen LE L’essor d’Internet, des ordinateurs personnels, des appareils numériques et mobiles changent diverses formes de communication, passant à sens unique comme

Social media uses web-based technologies to turn communication into interactive dialogues. Andreas Kaplan and Michael Haenlein define social media as "a group of Internet-based applications that build on the ideological and technological foundations of Web 2.0, which allows the creation and exchange of user-generated content."[1] Businesses also refer to social media as consumer-generated media (CGM). Social media utilization is believed to be a driving force in defining the current time period as the Attention Age. A common thread running through all definitions of social media is a blending of technology and social interaction for the co-creation of value. Distinction from industrial media People gain information, education, news, etc., by electronic media and print media. Social media are distinct from industrial or traditional media, such as newspapers, television, and film. They are relatively inexpensive and accessible to enable anyone (even private individuals) to publish or access information, compared to industrial media, which generally require significant resources to publish information.

  • Amazon, E-Commerce, and the New Brand World
    AMAZON, E-COMMERCE, AND THE NEW BRAND WORLD by JESSE D’AGOSTINO A THESIS Presented to the Department of Business Administration and the Robert D. Clark Honors College in partial fulfillment of the requirements for the degree of Bachelor of Arts June 2018 An Abstract of the Thesis of Jesse D’Agostino for the degree of Bachelor of Arts in the Department of Business to be taken June 2018 Amazon, E-commerce, and the New Brand World Approved: _______________________________________ Lynn Kahle This thesis evaluates the impact of e-commerce on brands by analyzing Amazon, the largest e-commerce company in the world. Amazon’s success is dependent on the existence of the brands it carries, yet its business model does not support its longevity. This research covers the history of retail and a description of e-commerce in order to provide a comprehensive understanding of our current retail landscape. The history of Amazon as well as three business analyses, a PESTEL analysis, a Porter’s Five Forces analysis, and a SWOT analysis, are included to establish a cognizance of Amazon as a company. With this knowledge, several aspects of Amazon’s business model are illustrated as potential brand diluting forces. However, an examination of these forces revealed that there are positive effects of each of them as well. The two sided nature of these factors is coined as Amazon’s Collective Intent. After this designation, the Brand Matrix, a business tool, was created in order to mitigate Amazon’s negative influence on both brands and its future. ii Acknowledgements I would like to thank Professor Lynn Kahle, my primary thesis advisor, for guiding me through this process, encouraging me to question the accepted and giving me the confidence to know that I would find my stride over time.

    SOCIAL NETWORKING WEB SITES: WHO SURVIVES? Andrea Mangani Department of Political Sciences University of Pisa [email protected] Via Serafini 3 56126 Pisa Italy Tel.: 00390502212438 Fax: 00390502212450 I would like to thank Adrian Wallwork, Giuseppe Vittucci, Simon Heckett, Massimiliano Vatiero, Ulrike Rohn, Nicola Giocoli, Jeffrey Ross Hyman and Vanessa Martini for their helpful observations. I also thank two anonymous referees for their insightful and important suggestions. 1 SOCIAL NETWORKING WEB SITES: WHO SURVIVES? ABSTRACT. This paper studies the relationship between the characteristics of social network sites (SNSs) and their probability of survival. The data sample includes 224 SNSs launched throughout the world from 1995 to 2015 and that can be described by focus strategy, business financing methods and interactions with external companies, such as partnerships, mergers and acquisitions. Three factors are systematically associated with closure hazard rates. First, compared with SNSs that address a specialized audience, generalist SNSs have a three times higher probability of closing. Second, being the target of a merger or acquisition more than doubles the probability of closure. Third, new entrants have a higher probability to survive if compared with SNSs with experience in the industry. JEL: D22, L82. KEYWORDS: social networking websites, mass media, media management, firm survival, duration analysis. 2 SOCIAL NETWORKING WEB SITES: WHO SURVIVES? 1. INTRODUCTION Network effects usually raise antitrust issues, because the “winners take it all” rule can lead to highly concentrated markets. In reality, network effects have negative consequences even on market definition and on the feasibility of empirical analyses. In fact, few subjects achieve a mass of users large enough to trigger an automatic network expansion.
