Managerial Assessments Of E-Business Investment Opportunities: A Field Study, Anandhi S. Bharadwaj, Amrit Tiwana
Managerial Assessments Of E-Business Investment Opportunities: A Field Study, Anandhi S. Bharadwaj, Amrit Tiwana
Research Collection School Of Computing and Information Systems
Managers charged with assessing investment opportunities for information technologies such as e-business projects face considerable uncertainty in their decision-making processes. Contemporary theories of the firm and the normative prescriptions thereof emphasize the potential for such investments to augment firm-level knowledge and relational capabilities. However, prior research has not examined the relative emphases that managers place on the knowledge and relational capability-augmenting characteristics of the e-business investments. In this paper, we develop a model to assess whether managerial evaluations of e-business investment opportunities are consistent with these normative and theoretical prescriptions. A test of the model using survey data on 485 …
The Implied Jump Risk Of Libor Rates, Kian Guan Lim, Christopher Ting, Mitch Warachka
The Implied Jump Risk Of Libor Rates, Kian Guan Lim, Christopher Ting, Mitch Warachka
Research Collection Lee Kong Chian School Of Business
This paper examines implied parameters from options on LIBOR futures. Jump-diffusion models are found to offer superior in-sample and out-of-sample performance when compared to their pure diffusion counterpart. The need to incorporate stochastic jump magnitudes into LIBOR dynamics is also documented. In addition, empirical evidence reveals that the jump component in LIBOR rates is important for pricing their derivatives. Furthermore, variation in jump risk often coincides with Federal Open Market Committee (FOMC) decisions and a small subset of macroeconomic announcements.
Dsim: A Distance-Based Indexing Method For Genomic Sequences, Xia Cao, Beng-Chin Ooi, Hwee Hwa Pang, Kian-Lee Tan, Anthony K. H. Tung
Dsim: A Distance-Based Indexing Method For Genomic Sequences, Xia Cao, Beng-Chin Ooi, Hwee Hwa Pang, Kian-Lee Tan, Anthony K. H. Tung
Research Collection School Of Computing and Information Systems
In this paper, we propose a Distance-based Sequence Indexing Method (DSIM) for indexing and searching genome databases. Borrowing the idea of video compression, we compress the genomic sequence database around a set of automatically selected reference words, formed from high-frequency data substrings and substrings in past queries. The compression captures the distance of each non-reference word in the database to some reference word. At runtime, a query is processed by comparing its substrings with the compressed data strings, through their distances to the reference words. We also propose an efficient scheme to incrementally update the reference words and the compressed …
Nil Is Not Nothing: Recognition Of Chinese Network Informal Language Expressions, Yunqing Xia, Wong, Wei Gao, Wei Gao
Nil Is Not Nothing: Recognition Of Chinese Network Informal Language Expressions, Yunqing Xia, Wong, Wei Gao, Wei Gao
Research Collection School Of Computing and Information Systems
Informal language is actively used in network-mediated communication, e.g. chat room, BBS, email and text message. We refer the anomalous terms used in such context as network informal language (NIL) expressions. For example, “偶(ou3)” is used to replace “我(wo3)” in Chinese ICQ. Without unconventional resource, knowledge and techniques, the existing natural language processing approaches exhibit less effectiveness in dealing with NIL text. We propose to study NIL expressions with a NIL corpus and investigate techniques in processing NIL expressions. Two methods for Chinese NIL expression recognition are designed in NILER system. The experimental results show that pattern matching method produces …
And/Or Graph And Search Algorithm For Discovering Composite Web Services, Qianhui (Althea) Liang, Stanley Y. W. Su
And/Or Graph And Search Algorithm For Discovering Composite Web Services, Qianhui (Althea) Liang, Stanley Y. W. Su
Research Collection School Of Computing and Information Systems
This paper presents a formalization of the Web Service composition problem as a search problem in an AND/OR graph, and a search algorithm for searching the graph to identify composite service(s) that satisfies a Web Service request. Given a service request that can only be satisfied by a composition of Web Services, we identify the service categories that are relevant to the request and dynamically construct an AND/OR graph to capture the input/output dependencies among the Web Services of these service categories. The graph is modified, based on the information provided in the service request. The search algorithm is then …
Towards Semantic Service Request Of Web Service Composition, Qianhui Althea Liang, Jen-Yao Chung, Steven M. Miller
Towards Semantic Service Request Of Web Service Composition, Qianhui Althea Liang, Jen-Yao Chung, Steven M. Miller
Research Collection School Of Computing and Information Systems
When meeting the challenges in automatic and semi-automatic Web service composition, capturing the user's service demand and preferences is as important as knowing what the services can do. This paper discusses the idea of semantic service requests for composite services, and presents a way to model the elements of a composite service request as user preferences and constraints. The model is based on an interactive and iterative strategy meant to obtain the exact requirements from potential service consumers. The markup vocabularies and associated inference mechanism of OWL-S are used as a means to bring semantics to service requests. Language constructs …

Agile Modeling, Agile Software Development, And Extreme Programming: The State Of Research, John Erickson, Kalle Lyytinen, Keng Siau
Agile Modeling, Agile Software Development, And Extreme Programming: The State Of Research, John Erickson, Kalle Lyytinen, Keng Siau
Research Collection School Of Computing and Information Systems
While there are many claims for the successful use of extreme programming (XP) and agile modeling (AM), and the proponents can often be vocal in the extreme regarding their supposed benefits, research evidence supporting proponents' claims is somewhat lacking. Currently, the only research appearing to investigate the phenomena consists of two prominent streams. A small number of case studies and experience reports that generally promote the success of XP in various development environments, and a well-established stream of research into pair programming has generated results that in part support the idea of XP. Research into AM appears to be even …
Informal Animation Sketching With K-Sketch, Richard C. Davis
Informal Animation Sketching With K-Sketch, Richard C. Davis
Research Collection School Of Computing and Information Systems
Animation is a powerful medium that is accessible to few, because current animation tools are extremely complex. This complexity arises partially from current tools’ focus on precise, often unnecessary details and partially from the difficulty of finding a small but sufficiently powerful set of tool features. We are designing K-Sketch, an informal 2D animation tool that uses sketching and demonstration to radically reduce the time needed to create an animation. Our field studies investigating the needs of current anima-tion tool users and would-be users are helping us to mini-mize complexity by showing us how to prioritize the many possible tool …

Research Collection School Of Computing and Information Systems
Mobile technology extends computing and the Internet into the wireless medium, and provides greater flexibility in communication, collaboration, and information sharing. In this research, we used the ‘Value-Focused Thinking’ approach to examine the strategic implications of mobile technology in a leading publishing company. The result is a means-ends objective network that depicts the fundamental objectives of using mobile technology and how the fundamental objectives can be achieved through means objectives. The research findings suggest three main strategic implications of mobile technology: (1) improve working process; (2) increase internal communication and knowledge sharing; and (3) enhance sales and marketing effectiveness.

Research Collection School Of Computing and Information Systems
In this paper, we describe our studies of cross-language and cross-media image retrieval at the ImageCLEF 2005. This is the first participation of our CUHK (The Chinese University of Hong Kong) group at ImageCLEF. The task in which we participated is the “bilingual ad hoc retrieval” task. There are three major focuses and contributions in our participation. The first is the empirical evaluation of language models and smoothing strategies for cross-language image retrieval. The second is the evaluation of cross-media image retrieval, i.e., combining text and visual contents for image retrieval. The last is the evaluation of bilingual image retrieval …
Forms Of Expression For Designing Visual Languages For Animation, Richard Christopher Davis, James A. Landay
Forms Of Expression For Designing Visual Languages For Animation, Richard Christopher Davis, James A. Landay
Research Collection School of Computing and Information Systems
We present further steps in our research into visual languages for animation. Animation is a rich mode of communication that is currently accessible to few, because animation systems are complex. Some systems try to make animation simple but put severe limits on users’ creative expression. Our field studies are demonstrating that would-be animators need to express animation in a wide variety of ways. We are developing a taxonomy of forms of expression for animation that will help the designers of visual languages for animation to determine which expressive forms to support. Our end goal is to build animation sketching systems …
Low Latency Multimedia Broadcast In Multi-Rate Wireless Meshes, Chun-Tong Chou, Archan Misra
Low Latency Multimedia Broadcast In Multi-Rate Wireless Meshes, Chun-Tong Chou, Archan Misra
Research Collection School Of Computing and Information Systems
In a multi-rate wireless network, a node can dynamically adjust its link transmission rate by switching between different modulation schemes. For the current IEEE802.11a/b/g standards, this rate adjustment is limited to unicast traffic only while multicast and broadcast traffic is always transmitted at the lowest possible rate. In this paper, we consider a novel type of multi-rate mesh networks where a node can dynamically adjust its link layer multicast rates to its neighbours. In particular, we consider the problem of realising low latency network-wide broadcast in this type of multi-rate wireless meshes. We will first show that the multi-rate broadcast …

Organizational resources account for the majority of unique variance explained in predicting innovation generation. Overall findings indicate that innovation is significantly and positively related to superior …
Partial Adjustable Autonomy In Multi-Agent Environment And Its Application To Military Logistics, Hoong Chuin Lau, Lucas Agussurja, Ramesh Thangarajoo
Partial Adjustable Autonomy In Multi-Agent Environment And Its Application To Military Logistics, Hoong Chuin Lau, Lucas Agussurja, Ramesh Thangarajoo
Research Collection School Of Computing and Information Systems
In a rapidly changing environment, the behavior and decision-making power of agents may have to be adaptive with respect to a fluctuating autonomy. In this paper, a centralized fuzzy approach is proposed to sense changes in environmental conditions and translate them to changes in agent autonomy. A distributed coalition formation scheme is then applied to allow agents in the new autonomy to renegotiate to establish schedule consistency. The proposed framework is applied to a real-time logistics control of a military hazardous material storage facility under peace-to-war transition.
Solving Generalized Open Constraint Optimization Problem Using Two-Level Multi-Agent Framework, Hoong Chuin Lau, Lei Zhang, Chang Liu
Solving Generalized Open Constraint Optimization Problem Using Two-Level Multi-Agent Framework, Hoong Chuin Lau, Lei Zhang, Chang Liu
Research Collection School Of Computing and Information Systems
The Open Constraint Optimization Problem (OCOP) refers to the COP where constraints and variable domains can change over time and agents' opinions have to be sought over a distributed network to form a solution. The openness of the problem has caused conventional approaches to COP such as branch-and-bound to fail to find optimal solutions. OCOP is a new problem and the approach to find an optimal solution (minimum total cost) introduced in [1] is based on an unrealistic assumption that agents are willing to report their options in nondecreasing order of cost. In this paper, we study a generalized OCOP …

Comment On "Realized Variance And Market Microstructure Noise" By Peter R. Hansen And Asger Lunde, Peter C. B. Phillips, Jun Yu
Research Collection School Of Economics
With the availability of ultra high frequency financial data, the task of finding an appropriate econometric model to describe the movement of financial variables at the tick-by-tick level has become an important goal in financial econometric research. The task has both theoretical and empirical dimensions. From an empirical perspective, the near continuous recording of financial asset prices has opened up the intriguing possibility of fitting the quadratic variation process empirically, leading to what is possibly the most direct nonparametric measure of asset price volatility. The resulting quantity has become known in the financial econometrics literature as realized variance (RV) and …

Research Collection School Of Computing and Information Systems
In order to organise and manage geospatial and georeferenced information on the Web making them convenient for searching and browsing, a digital portal known as G-Portal has been designed and implemented. Compared to other digital libraries, G-Portal is unique for several of its features. It maintains metadata resources in XML with flexible resource schemas. Logical groupings of metadata resources as projects and layers are possible to allow the entire metadata collection to be partitioned differently for users with different information needs. These metadata resources can be displayed in both the classification-based and map-based interfaces provided by G-Portal. G-Portal further incorporates …

Personalization Of Web Services: A Study On The Fit Between Web Tasks And Personalization Mechanisms, Fiona Fui-Hoon Nah, Keng Siau, Min Ling
Personalization Of Web Services: A Study On The Fit Between Web Tasks And Personalization Mechanisms, Fiona Fui-Hoon Nah, Keng Siau, Min Ling
Research Collection School Of Computing and Information Systems
Personalization is increasingly being considered an important ingredient of Web applications. In most cases, personalization techniques and mechanisms are used for tailoring information services to user needs. It is motivated by the recognition that a user has needs, and meeting them successfully is likely to lead to a satisfying relationship and re-use of the Web services offered. However, if the personalization mechanisms do not match the needs depicted by the tasks, it will decrease user satisfaction and performance. In this research, we use the cognitive fit theory to examine the fit between personalization mechanisms and Web tasks.
An Investigation Into The Continued Use Of Unified Modeling Language (Uml) In Information Systems Development, Keng Siau, X. Tan
An Investigation Into The Continued Use Of Unified Modeling Language (Uml) In Information Systems Development, Keng Siau, X. Tan
Research Collection School Of Computing and Information Systems
As the de facto standard for object-oriented modeling language, UML is expected to play an increasingly important role in information systems development. The long-term viability and eventual success of UML depend, to a great extent, on the continued use by UML users such as developers and analysts. Systematic investigations on UML’s continued use have been missing from contemporary discussions. Our study attempts to fill this gap in the literature. We developed a research model, which is primarily based on the Expectation Disconfirmation Theory (EDT). According to this model, UML users’ perceived discrepancy between pre-adoption expectation and post-adoption perceived performance, which …
Evaluation Criteria For Information Systems Development Methodologies, Keng Siau, Xin Tan
Evaluation Criteria For Information Systems Development Methodologies, Keng Siau, Xin Tan
Research Collection School Of Computing and Information Systems
The evaluation of information systems development methodologies is becoming increasingly important. The lack of a commonly acceptable set of criteria for evaluation, however, hinders aggregating knowledge from field studies. Our study attempts to fill the gap. To reduce the effects of subjectivity, we surveyed the opinions of a group (28) of experienced IS researchers. Fifty-one criteria were generated from the research participants. A systematic content analysis technique will be applied for grouping the unique criteria into general categories. Upon completion, our study can make both academic and practical contributions in evaluating ISD methodologies.

Dispatching Vehicles In A Mega Container Terminal, Ebru K. Bish, Frank Y. Chen, Thin Yin Leong, Barry L. Nelson, Jonathan W. C. Ng, David Simchi-Levi
Research Collection School Of Computing and Information Systems
We consider a container terminal discharging and uploading containers to and from ships. The discharged containers are stored at prespecified storage locations in the terminal yard. Containers are moved between the ship area and the yard using a fleet of vehicles, each of which can carry one container at a time. The problem is to dispatch vehicles to the containers so as to minimize the total time it takes to serve a ship, which is the total time it takes to discharge all containers from the ship and upload new containers onto the ship. We develop easily implementable heuristic algorithms …

Information Search Patterns In E-Commerce Product Comparison Services, Fiona Fui-Hoon Nah, Hong-Hee Lee, Liqiang Chen
Research Collection School Of Computing and Information Systems
The presentation of product information is very important in e-commerce websites. In this research, we study how disposition styles can influence users‟ search patterns in product comparison services of e-commerce websites. Our results show that people are inclined to use feature information paths in vertical disposition style and product information paths in horizontal disposition style. The results also indicate that there are more feature paths than product paths in the earlier stage of product comparison, and more product paths than feature paths in the latter stage of product comparison. Based on Gensch‟s two-stage choice model and the results of our …
Privacy Issues In The Era Of Ubiquitous Commerce, Holtjona Galanxhi, Fiona Fui-Hoon Nah
Privacy Issues In The Era Of Ubiquitous Commerce, Holtjona Galanxhi, Fiona Fui-Hoon Nah
Research Collection School Of Computing and Information Systems
The vision of ubiquitous commerce (u-commerce) is realized through the convergence of electronic, mobile, television, voice and silent commerce applications. The ubiquity, universality, uniqueness, and unison of u-commerce will provide two principal benefits for individual users and companies: increased convenience as well as more personalized and customized services. However, u-commerce will also bring new issues such as a greater degree of privacy concerns that will impact individual users, companies, and the society at large. This paper proposes and elaborates on a conceptual framework for privacy in the u-commerce era. It combines Lessig’s macro-level perspective – the four-factor model of privacy …

Towards A Theoretical Framework Of Information Systems Development Success, Y. Long, Keng Siau, M. Ling
Research Collection School Of Computing and Information Systems
Information systems development (ISD) is a complicated process involving interconnected resources, objects, and outcomes. The importance of ISD has attracted long-term interests from both researchers and practitioners. Based on the input-process-output model, this paper developed a conceptual framework of ISD success through a systematic literature review. The paper argues that ISD is a comprehensive and interactive process among individuals, teams, and organization. These factors impact ISD process, and further affect ISD success.
