Data Preparation For Social Network Mining And Analysis, Yazhe Wang

Dissertations and Theses Collection (Open Access)

This dissertation studies the problem of preparing good-quality social network data for data analysis and mining. Modern online social networks such as Twitter, Facebook, and LinkedIn have rapidly grown in popularity. The consequent availability of a wealth of social network data provides an unprecedented opportunity for data analysis and mining researchers to determine useful and actionable information in a wide variety of fields such as social sciences, marketing, management, and security. However, raw social network data are vast, noisy, distributed, and sensitive in nature, which challenge data mining and analysis tasks in storage, efficiency, accuracy, etc. Many mining algorithms cannot …

The (Un) Desirability Of Happiness: Pathogen Threats Predict Differences In The Value Of Happiness, Sharon Li Hua Koh

Dissertations and Theses Collection (Open Access)

People in some parts of the world find positive emotions more desirable than others. What accounts for this variability? We predicted that happiness would be valued less under conditions where the behaviors that happiness promotes would be less beneficial. We analyzed international survey data and United Nations voting records and found that happiness was valued relatively less in environments that had been historically pathogen-rich. Using a series of experimental studies, we showed that people who were experimentally primed by the threat of pathogens judged happiness in others less favorably and found happiness less appropriate. Our findings contribute to research on …

Anomaly Detection Through Enhanced Sentiment Analysis On Social Media Data, Zhaoxia Wang, Victor Joo, Chuan Tong, Xin Xin, Hoong Chor Chin

Research Collection School Of Computing and Information Systems

Anomaly detection in sentiment analysis refers to detecting abnormal opinions, sentiment patterns or special temporal aspects of such patterns in a collection of data. The anomalies detected may be due to sudden sentiment changes hidden in large amounts of text. If these anomalies are undetected or poorly managed, the consequences may be severe, e.g. A business whose customers reveal negative sentiments and will no longer support the establishment. Social media platforms, such as Twitter, provide a vast source of information, which includes user feedback, opinion and information on most issues. Many organizations also leverage social media platforms to publish information …

China Dream – 1, William A. Callahan

Research Collection School of Social Sciences

What Can the China Dream “Do” in the PRC?Since Xi Jinping chose “The China Dream” (中国梦) as his signature slogan in late 2012, much has been written on the topic. By mid-2014, 8,249 articles with “China dream-Zhongguo meng” in the title had been published within the PRC, according to the CNKI China academic journals database. Indeed, the 2014 round of major social science research grant funding in China was dominated by large projects that explore Comrade Xi’s thought in terms of the China dream. The China dream is also a popular topic among English-language journalistic and think tank commentaries, and …

Extracting Interest Tags From Twitter User Biographies, Ying Ding, Jing Jiang

Research Collection School Of Computing and Information Systems

Twitter, one of the most popular social media platforms, has been studied from different angles. One of the important sources of information in Twitter is users’ biographies, which are short self-introductions written by users in free form. Biographies often describe users’ background and interests. However, to the best of our knowledge, there has not been much work trying to extract information from Twitter biographies. In this work, we study how to extract information revealing users’ personal interests from Twitter biographies. A sequential labeling model is trained with automatically constructed labeled data. The popular patterns expressing user interests are extracted and …

Issues Of Social Data Analytics With A New Method For Sentiment Analysis Of Social Media Data, Zhaoxia Wang, Victor J. C. Tong, David Chan

Research Collection School of Social Sciences

Social media data consists of feedback, critiques and other comments that are posted online by internet users. Collectively, these comments may reflect sentiments that are sometimes not captured in traditional data collection methods such as administering a survey questionnaire. Thus, social media data offers a rich source of information, which can be adequately analyzed and understood. In this paper, we survey the extant research literature on sentiment analysis and discuss various limitations of the existing analytical methods. A major limitation in the large majority of existing research is the exclusive focus on social media data in the English language. There …

God And Discipline: Religious Education And Character Building In A Christian School In Jakarta, Chang Yau Hoon

Research Collection School of Social Sciences

A school is an institution in which student subjectivity is constituted and reinscribed through various 'disciplinary technologies'. The interplay between discipline and discipleship in the practice of Christian education is mutually constitutive. Through the study of a Protestant Christian school in Jakarta, this article explains the disciplinary technologies deployed by the school in its inculcation of discipline and character building. By examining the school's religious education practices the study provides insight into the perceptions of the school management, teachers and students with regard to various ethical, moral and religious issues. The author considers how Christian schools can develop critical reflective …

Introduction To Issue On Education For A Tolerant And Multicultural Indonesia, Lyn Parker, Chang Yau Hoon

Research Collection School of Social Sciences

Ethnic, religious and linguistic diversity is intrinsic to the concept of Indonesia. The national motto of Bhinneka Tunggal Ika, often translated as ‘Unity in Diversity’, though more directly translatable as ‘Diverse but One’, is emblazoned on the national symbol, the Garuda, which appears in classrooms, offices, statues and even living rooms all around the country. Indonesia has long enjoyed the reputation of a diverse and tolerant country. However, after the fall of Suharto in May 1998, it seemed to erupt in a conflagration of violence. Religious and ethnic conflicts alerted both citizens and scholars of Indonesia to the danger of …

Transnational Mobilities And The Making Of Creative Cities, Lily Kong

Research Collection School of Social Sciences

This review essay on the literature on creative cities pays particular attention to the ways in which transnational mobilities contribute significantly to the making of such cities. The paper reviews critically both the literature and phenomena of creative cities and their transnational flows by framing the discussion around the mobility of ideas (creative economy/creative city discourse), the mobility of people (the migration of the creative class), the mobility of technology (the travel of the creative cluster and architectural iconism phenomena), the mobility of finances (capital and investment flows), and the mobility of images (transnational artistic collaborations and products).

Young People's Attitudes Towards Inter-Ethnic And Inter-Religious Socializing, Courtship And Marriage In Indonesia, Lyn Parker, Chang Yau Hoon, Raihani Raihani

Research Collection School of Social Sciences

This paper presents the attitudes of high school students in Indonesia towards inter-ethnic and inter-religious socializing, courtship and marriage. It also explores how different personal characteristics and social conditions such as gender, ethnicity, type of school and community affect these attitudes. The basic findings come from a survey of more than 3,000 students in senior high schools in five provinces of Indonesia: Jakarta, Yogyakarta, West Sumatra, Central Kalimantan and Bali. Survey data were supplemented with data from interviews and focus group discussions with students and from participant observation in and around the same schools. The authors found that most students …

Rural Electrification And Development In South Korea, Terry Van Gevelt

Research Collection College of Integrative Studies

In fifteen years, South Korea went from providing only 12% of rural households with electricity to providing 98% of rural households with electricity for lighting and productive uses. This paper provides an analysis of rural electrification and development in South Korea from 1965 to 1979 and finds that rural electrification contributed to a significant increase in rural household income levels and improved the quality of life in villages substantially. At the same time, rural electrification did not benefit the poorest quartile of rural households, increased economic and social inequality, led to a significant increase in household debt, and accelerated migration …

On The Limitations Of Using Situational Judgement Tests To Measure Interpersonal Skills: The Moderating Influence Of Employee Anger, Jerel E. Slaughter, Michael S. Christian, Nathan P. Podsakoff, Evan F. Sinar, Filip Lievens

Research Collection Lee Kong Chian School Of Business

Many authors have suggested that situational judgment tests (SJTs) are useful tools for assessing applicants because SJT items can be written to assess a number of job-related knowledges, skills, abilities and other characteristics (KSAOs). However, SJTs may not be appropriate for measuring certain KSAOs for some applicants. We posit that using SJTs to measure interpersonal skills may lead to invalid inferences about applicants with higher levels of angry hostility (AH), and thus, AH should moderate the relation between interpersonally oriented SJTs and job performance. Three studies, using samples of healthcare workers (n = 225), police officers (n = 54), and …

Was Singapore Airlines Liable For Business-Class Seats Sold At Economy Rates?, Yihan Goh

Research Collection Yong Pung How School Of Law

Much has been reported about Singapore Airlines (“SIA”) mistakenly charging economy rates for around 900 business-class seats due to a computer input error. Yesterday, SIA said that it would honour those tickets at economy rates, reversing its previous position that it would not, and closing the episode on a note of goodwill. This blog entry explores the legal analysis behind the episode on the assumption that Singapore contract law applies, so as to maintain its general relevance to a Singaporean audience and its specific application to online retailers concerned about making similar pricing errors. Of course, the analysis would differ …

R1 International Pte Ltd V Lonstroff Ag [2014] Sgca 56: Lessons In Contractual Formation, Yihan Goh

Research Collection Yong Pung How School Of Law

The rules relating to contractual formation are easy to state but difficult to apply in the varied circumstances of practice. It is therefore helpful that the recent Court of Appeal decision of R1 International Pte Ltd v Lonstroff AG [2014] SGCA 56 (“R1 International”) provides much guidance in this area of the law.

R1 International concerned whether a set of terms to arbitrate in Singapore, found in a detailed contract note sent by the appellant to the respondent shortly after their deal (“the deal”) was concluded, was incorporated as part of the contract between the parties. The answer …

On Bias In The Estimation Of Structural Break Points, Liang Jiang, Xiaohu Wang, Jun Yu

Research Collection School Of Economics

Based on the Girsanov theorem, this paper obtains the exact Önite sample distribution of the maximum likelihood estimator of structural break points in a continuous time model. The exact Önite sample theory suggests that, in empirically realistic situations, there is a strong Önite sample bias in the estimator of structural break points. This property is shared by least squares estimator of both the absolute structural break point and the fractional structural break point in discrete time models. A simulation-based method based on the indirect estimation approach is proposed to reduce the bias both in continuous time and discrete time models. …

Executive Overreach By Minority Governments, Madhav S. Aney, Shubhankar Dam

Research Collection School Of Economics

A provision in the Indian constitution allows the executive to make laws in the event oneof the two houses of parliament is not in session. This provision was intended to allow theexecutive to act in case there’s an immediate legislative necessity and the parliament cannotbe convened. Using a bargaining model with asymmetric information we show how partieswithin the parliament may reach an agreement on legislations when the ruling party does notcommand a majority (minority government). The model makes predictions about lawmakingpatterns by the legislature when the parliament is in session, and ordinances by the executivewhen the parliament is not in …

Enhancing Training Motivation In The Public Sector In South Korea: The Value Of A Contingency Approach, Yong Hyun Kim, Ong, Madeline, Jang Hoon Chung

Research Collection Lee Kong Chian School Of Business

Public sector organisations which invest in trainingprogrammes care about their employees’ successful application of learntknowledge and skills in the workplace. The present study finds that leadersupport positively influences public sector employees’ training motivation,specifically the motivation to transfer learnt knowledge and skills to theirjobs. However, this positive relationship is moderated by employees’ priorknowledge of training content. When employees have high levels of priorknowledge of training content, leader support is not a significant influence ontheir motivation to transfer learnt knowledge and skills to their jobs. Thesefindings are derived from a survey of 335 South Korean government officials whorecently participated in a training …

Testing The Martingale Hypothesis, Peter C. B. Phillips, Sainan Jin

Research Collection School Of Economics

We propose new tests of the martingale hypothesis based on generalized versions of the Kolmogorov–Smirnov and Cramér–von Mises tests. The tests are distribution-free and allow for a weak drift in the null model. The methods do not require either smoothing parameters or bootstrap resampling for their implementation and so are well suited to practical work. The article develops limit theory for the tests under the null and shows that the tests are consistent against a wide class of nonlinear, nonmartingale processes. Simulations show that the tests have good finite sample properties in comparison with other tests particularly under conditional heteroscedasticity …

Emotional Disclosure On Social Networking Sites: The Role Of Network Structure And Psychological Needs, Han Lin, William Tov, Lin Qiu

Research Collection School of Social Sciences

We conducted three studies to understand how online emotional disclosure is influenced by social network structure on Facebook. Results showed that emotional disclosure was associated with both the density and size of users’ personal networks. Facebook users with denser networks disclosed more positive and negative emotions, and the relation between network density and emotional disclosure was mediated by stronger need for emotional expression. Facebook users with larger networks on Facebook disclosed more positive emotions, and the relation between network size and emotional disclosure was mediated by a stronger need for impression management. Our study extends past research by revealing the …

Research Collection School Of Computing and Information Systems

Doing business on social media has become a common practice for many companies these days. While the contents shared on Twitter and Facebook offer plenty of opportunities to uncover business insights, it remains a challenge to sift through the huge amount of social media data and identify the potential social audience who is highly likely to be interested in a particular company. In this paper, we analyze the Twitter content of an account owner and its list of followers through various text mining methods, which include fuzzy keyword matching, statistical topic modeling and machine learning approaches. We use tweets of …
