Topic Analysis Of Tweets On The European Refugee Crisis Using Non-Negative Matrix Factorization, Chong Shen

CMC Senior Theses

The ongoing European Refugee Crisis has been one of the most popular trending topics on Twitter for the past 8 months. This paper applies topic modeling on bulks of tweets to discover the hidden patterns within these social media discussions. In particular, we perform topic analysis through solving Non-negative Matrix Factorization (NMF) as an Inexact Alternating Least Squares problem. We accelerate the computation using techniques including tweet sampling and augmented NMF, compare NMF results with different ranks and visualize the outputs through topic representation and frequency plots. We observe that supportive sentiments maintained a strong presence while negative sentiments such …

Pre-Service Teacher Social Networking Decisions And Training Needs: A Mixed Methods Study, Helen Crompton, Kelly Rippard, Jody Sommerfeldt

Teaching & Learning Faculty Publications

The use of social networks in America has risen nearly tenfold in a decade, rising from 7% in 2005 to 65% in 2015. This rise in the use of social networks has presented new ethical, legal, and professional challenges for educators. Teachers are held to higher standards of moral behavior than the general population. This mixed-methods study examined the types of social networks used by pre-service teachers and if they are making good decisions when using social networks. The findings show that the pre-service teachers were unsure what to post. Based on this finding, the researchers provide training suggestions to …

Posting Topics ≠ Reading Topics: On Discovering Posting And Reading Topics In Social Media, Wei Gong, Ee-Peng Lim, Feida Zhu

Research Collection School Of Computing and Information Systems

Social media users make decisions about what content to post and read. As posted content is often visible to others, users are likely to impose self-censorship when deciding what content to post. On the other hand, such a concern may not apply to reading social media content. As a result, the topics of content that a user posted and read can be different and this has major implications to the applications that require personalization. To better determine and profile social media users’ topic interests, we conduct a user survey in Twitter. In this survey, participants chose the topics they like …

Research Collection School Of Computing and Information Systems

Geotagged social media is becoming highly popular as social media access is now made very easy through a wide range of mobile apps which automatically detect and augment social media posts with geo-locations. In this paper, we analyze two kinds of location-based patterns. The first is the association between location attributes and the locations of user tweets. The second is location association pattern which comprises a pair of locations that are co-visited by users. We demonstrate that through tracking the Twitter data of Singapore-based users, we are able to reveal association between users tweeting from school locations and the school …

A Comparison Of Fundamental Network Formation Principles Between Offline And Online Friends On Twitter, Felicia Natali, Feida Zhu

Research Collection School Of Computing and Information Systems

We investigate the differences between how some of the fundamental principles of network formation apply among offline friends and how they apply among online friends on Twitter. We consider three fundamental principles of network formation proposed by Schaefer et al.: reciprocity, popularity, and triadic closure. Overall, we discover that these principles mainly apply to offline friends on Twitter. Based on how these principles apply to offline versus online friends, we formulate rules to predict offline friendship on Twitter. We compare our algorithm with popular machine learning algorithms and Xiewei’s random walk algorithm. Our algorithm beats the machine learning algorithms on …

All Graduate Theses, Dissertations, and Other Capstone Projects

Today's college students are digital natives who have grown up using technology, such as social network systems (SNSs). SNS use, and specific behavior patterns, have been linked to a variety of psychological and social outcomes. The sense of disconnection from a student's institution, known as alienation, is one significant factor that can be detrimental to students' social and academic experience and performance in college (Gordon, 1998; Loo & Rolison, 1986; Suen, 1983). This study explores the association between Facebook relationship maintenance behaviors (FRMB; Ellison, Vitak, Gray, & Lampe, 2014) and alienation from their university, and whether FRMBs and alienation are …

Conceptual Models On The Effectiveness Of E-Marketing Strategies In Engaging Consumers, Cheristena Bolos, Efosa C. Idemudia, Phoebe Mai, Mahesh Rasinghani, Shelley Smith

Journal of International Technology and Information Management

Effective marketing has always been an important factor in business success. Without the ability to identify customers and convince them to purchase the product or service being offered, businesses would not survive. Recent advancements in technology have given rise to new opportunities to engage customers through the use of electronic marketing (e-marketing). E- marketing draws from traditional marketing principles, while also expanding the types of strategies available to companies. Websites, social media, and online marketplaces are just some examples of how businesses are leveraging e-marketing approaches to connect with potential customers.

Healthcare System-Use Behavior: A Systematic Review Of Its Determinants, Jiming Wu

Journal of International Technology and Information Management

To understand patient and physician behavior, researchers have investigated the determinants of using healthcare information systems. Although this stream of research has produced important findings, it has yet to appreciably advance our understanding of system-use behavior in healthcare. To fill this gap, the current paper employs a systematic review to synthesize past research, reveal the key determinants of healthcare system usage, and illuminate a deeper understanding of the topic. This study thus helps healthcare researchers expand their baseline knowledge of these core determinants and conduct more fruitful future research on system-use behavior in healthcare.

Friendship Maintenance And Prediction In Multiple Social Networks, Roy Ka-Wei Lee, Ee-Peng Lim

Research Collection School Of Computing and Information Systems

Due to the proliferation of online social networks (OSNs), users find themselves participating in multiple OSNs. These users leave their activity traces as they maintain friendships and interact with other users in these OSNs. In this work, we analyze how users maintain friendship in multiple OSNs by studying users who have accounts in both Twitter and Instagram. Specifically, we study the similarity of a user's friendship and the evenness of friendship distribution in multiple OSNs. Our study shows that most users in Twitter and Instagram prefer to maintain different friendships in the two OSNs, keeping only a small clique of …

Factors Influencing Young Bystanders' Decisions To Intervene When Witnessing Cyber-Aggression: A Mixed Methods Exploration, Lisa Jodi Patterson

Theses: Doctorates and Masters

With the modern proliferation of computers, the Internet and smart phones, adolescents are at increased risk of cyber-aggression: negative, harmful behaviour expressed through electronic means and aimed at an individual (or group of individuals). Cyber-aggression can have serious consequences for the social, emotional and physical health of both targets and perpetrators. Some experts recommend tackling cyberaggression using the strategies applied to face-to-face forms of aggression and bullying in school environments. One such strategy is to encourage peer bystanders to intervene in a positive way, which has been demonstrated to influence both the duration and severity of bullying episodes in the …

We investigate the influence of offline friendship in three specific areas of Twitter networking behaviors: (a) network structure, (b) Twitter content and (c) interaction on Twitter. We observe some interesting findings through the empirical analysis of 2193 pairs of users who are online friends. When these pairs of users know each other offline, they are more likely to (1) respond to the online gesture of friendship from their friend, (2) share mutual online friends, (3) distribute and gather information in their friend’s Twitter network, (4) pay attention to their friend’s tweets, (5) post tweets that might be of interest to …

The Relationship Between Problem-Solving Ability/Eating Motivation And Perceived Quality Of Life In Individuals Diagnosed With Celiac Disease, Vincenzo Zaccheo

PCOM Psychology Dissertations

Celiac disease (CD) is a digestive disorder resulting from gluten intolerance that leads to damage of the small intestine. The only current available treatment for CD involves adherence to a strict gluten-free diet. Due to the restrictive nature of this treatment diet, and the increasing prevalence of CD in recent years, much research has been conducted examining factors that impact the quality of life (QOL) of individuals with CD. However, there has been a dearth of literature identifying those factors which can be modified within a treatment setting. Thus, a need for further research in this area was identified. Through …

Modeling Social Media Content With Word Vectors For Recommendation, Ying Ding, Jing Jiang

Research Collection School Of Computing and Information Systems

In social media, recommender systems are becoming more and more important. Different techniques have been designed for recommendations under various scenarios, but many of them do not use user-generated content, which potentially reflects users’ opinions and interests. Although a few studies have tried to combine user-generated content with rating or adoption data, they mostly reply on lexical similarity to calculate textual similarity. However, in social media, a diverse range of words is used. This renders the traditional ways of calculating textual similarity ineffective. In this work, we apply vector representation of words to measure the semantic similarity between text. We …

Life Beyond The Like: Uses And Gratifications Of Sharing Business Facebook Page Content, Sara M. Nash

College of Journalism and Mass Communications: Theses

One of the main reasons businesses create a Facebook Page is to solidify relationships with existing customers who are Facebook users and to leverage those relationships to gain new customers. Many studies have asked Facebook users to articulate the gratifications they receive when “liking” a business Facebook Page. These studies help explain what gratifications users gain by connecting to businesses via Facebook. To expand on these findings, the current pilot study applied the uses and gratifications theory to identify Facebook users’ motivations to “share” business Facebook content within their own personal network. Understanding users’ reasons for “sharing” will help businesses …

Two Formulas For Success In Social Media: Learning And Network Effects, Liangfei Qiu, Qian Tang, Andrew B. Whinston

Research Collection School Of Computing and Information Systems

Recent years have witnessed an unprecedented explosion in information technology that enables dynamic diffusion of user-generated content in social networks. Online videos, in particular, have changed the landscape of marketing and entertainment, competing with premium content and spurring business innovations. In the present study, we examine how learning and network effects drive the diffusion of online videos. While learning happens through informational externalities, network effects are direct payoff externalities. Using a unique data set from YouTube, we empirically identify learning and network effects separately, and find that both mechanisms have statistically and economically significant effects on video views; furthermore, the …
