Nowadays, it is a heated topic for many industries to build automatic question-answering (QA) systems. A key solution to these QA systems is to retrieve from a QA knowledge base the most similar question of a given question, which can be reformulated as a paraphrase identification (PI) or a natural language inference (NLI) problem. However, most existing models for PI and NLI have at least two problems: They rely on a large amount of labeled data, which is not always available in real scenarios, and they may not be efficient for industrial applications. In this paper, we study transfer learning …

This paper discusses the digital payment scenario unfolding in Singapore as the country’s government ponders the tremendous leap made by China in the digital payment space. The paper discusses possible key factors contributing to the success of digital payments in China, such as the success of WeChat, and whether this could be replicated in a country like Singapore. Although China and Singapore are vastly different in size, they share many similarities, including a strong one-party government which is actively involved in the direction and growth of the economy. Both countries share similar cultural and social influences including materialism, IT adoption …
Influence Of Online Consumer Reviews On Brand Choice, Patricia Lui
Influence Of Online Consumer Reviews On Brand Choice, Patricia Lui
Research Collection Lee Kong Chian School Of Business
Social interaction encourages consumers toshare information in the digital age. Many consumers use online reviews of products and services to supporttheir brand choice. The concept ofreference group explains how peers can influence consumer purchasedecisions. Peers can exert influence onconsumers in the forms of informational, utilitarian and value-expressiveinfluences. This proposed study aims atexamining how these three forms of reference group influence would affectconsumers in using online consumer reviews when making a brand choice decision. It also explores the role of brand trust onthe brand choice. This paper serves thepurpose of providing a conceptual framework for developing further research.

Many firms allocate increasing parts of their advertising budgets to banner advertising. Yet, for firms that predominantly sell offline, existing research provides little guidance on online advertising decisions. In this study, the authors analyze the impact of banner advertising on consumers' online and offline behavior across multiple distinct campaigns for one focal firm, which predominantly sells through the offline channel. Results suggest that banner and TV advertising increase website visit incidence for consumers who had not visited the focal firm's website in the previous four weeks (non-recent online consumers). For these consumers, banner and TV advertisements indirectly increase offline sales …

Smart Contracts: Terminology, Technical Limitations And Real World Complexity, Eliza Mik
Research Collection Yong Pung How School Of Law
If one is to believe the popular press and many “technical writings,” blockchains create not only a perfect transactional environment but also obviate the need for banks, lawyers and courts. The latter will soon be replaced by smart contracts: unbiased and infallible computer programs that form, perform and enforce agreements. Predictions of future revolutions must, however, be distinguished from the harsh reality of the commercial marketplace and the technical limitations of blockchains. The fact that a technological solution is innovative and elegant need not imply that it is commercially useful or legally viable. Apart from attempting a terminological “clean-up” surrounding …

Online retail business has become an emerging market for almost all business owners. Online recommender systems provide better service to consumers during their decision making processes. In this study, a controlled lab experiment was conducted to assess the effect of recommendation timing (early, mid, and late) and recommendation source (expert reviews vs. consumer reviews) on online consumers’ interest and attention. Eye-tracking data was extracted from the experiment and analyzed. The results suggest that consumers show more interest in recommendation based on consumer reviews than expert reviews. Earlier recommendations do not receive greater attention than later recommendations.
How To Enable Future Faster Payments? An Evaluation Of A Hybrid Payments Settlement Mechanism, Zhiling Guo, Yuanzhi Huang
How To Enable Future Faster Payments? An Evaluation Of A Hybrid Payments Settlement Mechanism, Zhiling Guo, Yuanzhi Huang
Research Collection School Of Computing and Information Systems
In the era of Fintech innovation and e-commerce, faster settlement of massive retail transactions is crucial for business growth and financial system stability. However, speeding up payments settlement can create periodic liquidity shortfalls to banks which would incur high cost of funds in the settlement process. We propose a new hybrid settlement mechanism design that integrates features of real-time gross settlement, deferred net settlement, and central queue management structure. The hybrid mechanism is managed by an intermediary and is particularly suitable to settle large volume of small-value retail payments. We evaluate the mechanism using computer experiments and simulation. We find …

Online Advertising, Retail Platform Openness, And Long Tail Sellers, Jianqing Chen, Zhiling Guo
Research Collection School Of Computing and Information Systems
It becomes increasingly popular that some large online retailers such as Amazon open their platforms to allow third-party retail competitors to sell on their own platforms. We develop an analytical model to examine this retailer market place model and its business impact. We assume that a leading retailer has both valuation advantage that may come from its reputation and information advantage that may come from its brand awarenewss. We find that the availability of relatively low-cost advertising through social media or search engine can effectively reduce the leading retailer's information advantage, and thus be an important driving force for its …

On Self-Selection Biases In Online Product Reviews, Nan Hu, Paul A. Pavlou, Jie Zhang
Research Collection School Of Computing and Information Systems
Online product reviews help consumers infer product quality, and the mean (average) rating is often used as a proxy for product quality. However, two self-selection biases, acquisition bias (mostly consumers with a favorable predisposition acquire a product and hence write a product review) and underreporting bias (consumers with extreme, either positive or negative, ratings are more likely to write reviews than consumers with moderate product ratings), render the mean rating a biased estimator of product quality, and they result in the well-known J-shaped (positively skewed, asymmetric, bimodal) distribution of online product reviews. To better understand the nature and consequences of …

Crowdfunding: Financing Ventures In The Digital Era, Srinivas K. Reddy, Yee Heng Tan
Research Collection Lee Kong Chian School of Business
Over the past few years, digital platforms have emerged as a new way to disrupt industries. These platforms not only connect riders and drivers, like Uber, or hosts and guests, like Airbnb, but also ventures and funders. Crowdfunding platforms like Lendingclub or Kickstarter have gained widespread visibility and acceptance in recent years. Crowdfunding was virtually non-existent until 2010 but has been growing exponentially since 2010. In 2015, the volume rose to US$34.4 billion, slightly surpassing the venture capitalist industry and is expected to continue growing quickly.

Factored Similarity Models With Social Trust For Top-N Item Recommendation, Guibing Guo, Jie Zhang, Feida Zhu, Xingwei Wang
Research Collection School of Computing and Information Systems
Trust-aware recommender systems have attracted much attention recently due to the prevalence of social networks. However, most existing trust-based approaches are designed for the recommendation task of rating prediction. Only few trust-aware methods have attempted to recommend users an ordered list of interesting items, i.e., item recommendation. In this article, we propose three factored similarity models with the incorporation of social trust for item recommendation based on implicit user feedback. Specifically, we introduce a matrix factorization technique to recover user preferences between rated items and unrated ones in the light of both user-user and item-item similarities. In addition, we claim …
Inferring User Consumption Preferences From Social Media, Yang Li, Jing Jiang, Ting Liu
Inferring User Consumption Preferences From Social Media, Yang Li, Jing Jiang, Ting Liu
Research Collection School Of Computing and Information Systems
Social Media has already become a new arena of our lives and involved different aspects of our social presence. Users' personal information and activities on social media presumably reveal their personal interests, which offer great opportunities for many e-commerce applications. In this paper, we propose a principled latent variable model to infer user consumption preferences at the category level (e.g. inferring what categories of products a user would like to buy). Our model naturally links users' published content and following relations on microblogs with their consumption behaviors on e-commerce websites. Experimental results show our model outperforms the state-of-the-art methods significantly …

Faster Internet connections and advanced streaming technologies have boosted the consumption of digital entertainment content. Nonetheless, many content providers are still struggling to differentiate their services and sell their offerings in the market, due to the large number of options available and customers’ uncertainty about the specific attributes of individual information goods. The providers employ different strategies to communicate information on the quality and fit of their products. In this research, I examine the effectiveness of sampling-based seller strategy on the marketing of digital entertainment goods. Using a large dataset on series drama on-demand, I show that content sampling plays …

Research Collection School Of Computing and Information Systems
Product reviews greatly influence purchase decisions in online shopping. A common burden of online shopping is that consumers have to search for the right answers through massive reviews, especially on popular products. Hence, estimating and predicting the helpfulness of reviews become important tasks to directly improve shopping experience. In this paper, we propose a new approach to helpfulness prediction by leveraging aspect analysis of reviews. Our hypothesis is that a helpful review will cover many aspects of a product at different emphasis levels. The first step to tackle this problem is to extract proper aspects. Because related products share common …

No discussion of “Law and Technology” would be complete without at least one essay centred on the Internet. While the Internet no longer captures our imagination with the same force as it did 20 years ago, we cannot assume that it no longer creates (or perpetuates?) multiple legal problems. When we talk about the Internet we must, however, refrain from the popular “Internet metanarrative” that often leads to superficial arguments and unhelpful generalisations.1 We must always remain aware of the multiplicity of the Internet’s technical applications and the wide range of legal contexts in which the term gains significance.

The Erosion Of Autonomy In Online Consumer Transactions, Eliza Mik
Research Collection Yong Pung How School Of Law
Online businesses influence consumer behaviour by means of a wide range of technologies that determine what information is displayed as well as how and when it is displayed. This creates an unprecedented power imbalance between the transacting parties, raising questions not only about the permissible levels of procedural exploitation in contract law, together with the adequacy of existing consumer protections but also about the impact of technology on consumer autonomy. There is, however, no single technology that threatens the latter. It is the combined, mutually-enforcing effect of multiple technologies that influence consumer choices at different stages in the transacting process, …

Understanding factors that influence online shopping and managing consumer relationships is not a trivial task for firms, considering the many pertinent factors that influence behavior, including the product being shopped (i.e., the “what”) and the context of the website itself (i.e., the “where”). This study investigates the impact of these characteristics on an online transaction’s basket value, after incorporating the role of other aspects of the browsing process including page views and visit duration. The authors estimate a multivariate mixed-effects Type II Tobit model with a system of equations to explain variation in shopping basket value, using data involving 773,262 …

Rapid expansion of e-commerce, along with rising domestic and cross-border payments, has fueled the demand among financial institutions for a cost-effective means to expedite clearing and settlement of low-value retail payments. These are called faster payments settlement systems. Traditionally, retail payments have made extensive use of interbank netting systems, in which payments are accumulated for end-of-day settlement. This approach, known as deferred net settlement (DNS), reduces the liquidity needs of the payment system, but bears inherent operational and financial risks for unsettled intraday payments. As large dollar volumes of retail payments accumulate, real-time gross settlement (RTGS) has been recognized as …

In this study, we empirically examine the effect of local shoe store openings on the sales of a competing, major online shoe retailer. Both showrooming and competing effects can play a role: Under the showrooming effect, the local store opening can lead to more online sales for the online retailer, whereas the competing effect created by the local store opening can substitute away the demand for the online retailer. We examine when one effect dominates the other by classifying local stores into single- and mixed-brand stores. We find that the showrooming effect is dominant for a single-brand store opening, and …

Electronic Contract Signing Without Using Trusted Third Party, Zhiguo Wan, Robert H. Deng, David Kuo Chuen Lee
Research Collection School Of Computing and Information Systems
Electronic contract signing allows two potentially dis-trustful parties to digitally sign an electronic document “simultaneously” across a network. Existing solutions for electronic contract signing either require the involvement of a trusted third party (TTP), or are complex and expensive in communication and computation. In this paper we propose an electronic contract signing protocol between two parties with the following advantages over existing solutions: 1) it is practical and scalable due to its simplicity and high efficiency; 2) it does not require any trusted third party as the mediator; and 3) it guarantees fairness between the two signing parties. We achieve …

When e-commerce giant Alibaba went public on the New York Stock Exchange in September 2014, its market capitalisation rocketed to roughly US$219 billion - a sum greater than any record previously set by its American contemporaries, Facebook, eBay and Amazon. It was a historic event that led many to believe that China’s digital economy was echoing the Middle Kingdom’s own meteoric rise onto the world-stage. China ranks high in digital connectivity. In 2015, almost half of the country’s population, or 649 million people, were online. It’s fast-growing Internet economy generates about US$100 billion annually and is predicted to reach US$277 …
