E-Commerce Systems Development Methodologies, M. Rossi, Keng Siau, S. Purao

Research Collection School Of Computing and Information Systems

Methodologies. This is the first time we organize this new minitrack on electronic commerce systems development. The flexibility, scalability, user-friendliness, privacy, security, intuitiveness, and other important characteristics of electronic commerce systems make the systems development process of such systems very multifaceted and complex. Today, most electronic commerce systems are built based on intuition and rule of thumbs.Many practitioners have the misconception that there is no need for a systematic modeling and design technique for these systems. The lack of appropriate methods and methodologies to support electronic commerce systems development is another stumbling block. Most of the widely used methods are …

An Integrated Data Mining System To Automate Discovery, Cecil Chua, Roger Hsiang-Li Chiang, Ee Peng Lim Jan 2000

An Integrated Data Mining System To Automate Discovery, Cecil Chua, Roger Hsiang-Li Chiang, Ee Peng Lim

Research Collection School Of Computing and Information Systems

Many data analysts require tools which can integrate their database management packages (e.g. Microsoft Access) with their data analysis ones (e.g. SAS, SPSS), and provide guidance for the selection of appropriate mining algorithms. In addition, the analysts need to extract and validate statistical results to facilitate data mining. In this paper, we describe an integrated data mining system called the Linear Correlation Discovery System (LCDS) that meets the above requirement. LCDS consists of four major sub-components, two of which, the selection assistant and the statistics coupler, are discussed in this paper. The former examines the schema and instances to determine …

The Integration Of Relationship Instances From Heterogeneous Databases, Ee Peng Lim, Roger Hsiang-Li Chiang Jan 2000

The Integration Of Relationship Instances From Heterogeneous Databases, Ee Peng Lim, Roger Hsiang-Li Chiang

Research Collection School Of Computing and Information Systems

In the process of integrating legacy databases, one has to resolve inter-database conflicts at both the schema and instance levels. In this paper, we discuss relationship conflicts as a special type of conflicts to be resolved during the database integration. Relationships are properties that relate real world objects. So far, most inter-database relationship conflicts are addressed at the schema-level by various schema integration techniques. However, instance-level relationship conflicts are largely neglected. This paper therefore investigates the causes of instance-level relationship conflicts and proposes a taxonomy for classifying instance-level relationship conflicts. In addition, we develop a systematic process to resolve instance-level …

The E-Landscape: An Unexplored Goldmine Of The New Millennium, Thow Yick Liang Jan 2000

The E-Landscape: An Unexplored Goldmine Of The New Millennium, Thow Yick Liang

Research Collection Lee Kong Chian School Of Business

The Internet is an intangible cyberworld created by the human mind. Exploring and exploiting this e-landscape requires a totally redefined mindset. The fact that it exists in the mental realm also makes it a nonlinear system. In this respect, understanding both intangible and nonlinear dynamics is a requisite to the proper exploitation of e-commerce. The e-landscape is a new edge of chaos where order and disorder co-exist. It could be a goldmine for those who swiftly recognize structure in this highly disordered territory. The tremendous number of opportunities and uncertainties embedded in the submerged portion of this iceberg are still …

Measuring Information Quality Of Web Site: Development Of Instrument, P. Katerattanakul, Keng Siau

Research Collection School Of Computing and Information Systems

Web sites have been extensively used to provide information to consumers. While practitioners and researchers have proposed different criteria for effective Web site design based on common sense, intuition, and rules-ofthumb, effective Web site design focusing on the quality of the information it provides has rarely been studied. In this research, we propose a framework and develop an instrument to measure the information quality of individual or personal Web sites. The theoretical foundation of this research is the information quality framework. The proposed framework and instrument were tested in an individual or personal Web site context.

The Window Distribution Of Multiple Tcps With Random Loss Queues, Archan Misra, Teunis Ott, John Baras Dec 1999

The Window Distribution Of Multiple Tcps With Random Loss Queues, Archan Misra, Teunis Ott, John Baras

Research Collection School Of Computing and Information Systems

Two approximate techniques for analyzing the window size distribution of TCP flows sharing a RED-like bottleneck queue are presented. Both methods presented first use a fixed point algorithm to obtain the mean window sizes of the flows, and the mean queue length in the bottleneck buffer. The simpler of the two methods then uses the ‘square root formula’ for TCP; the other method is more complicated. More often than not, the simpler method is slightly more accurate; this is probably due to the fact that window sizes of the different flows are negatively correlated.

Organizing Culture: Leader Roles, Behaviors, And Reinforcement Mechanisms, Gerard George, Randall G. Sleeth, Mark A. Siders Dec 1999

Organizing Culture: Leader Roles, Behaviors, And Reinforcement Mechanisms, Gerard George, Randall G. Sleeth, Mark A. Siders

Research Collection Lee Kong Chian School Of Business

Organizational leaders provide the primary impetus in defining, forming and shaping corporate culture. Leadership literature emphasizes on the leader's role in "articulating a vision" and the leader's pivotal role in establishing culture by setting objectives and then removing hurdles by smoothing the path for attaining those objectives. The model of corporate culture transmission focuses on behaviors that corporate leaders employ to create, communicate and manage corporate culture. However, the model does not emphasize interpretation and identification with leader behaviors in ways that would cause members to embrace the leader's values and beliefs. Improved focus over two decades does not yet …

A query routing broker is a software agent that determines from a large set of accessing information sources the ones most relevant to a user's information need. As the number of information sources on the Internet increases dramatically, future users will have to rely on query routing brokers to decide a small number of information sources to query without incurring too much query processing overheads. In this paper, we describe a query routing broker known as ZBroker developed for bibliographic database servers that support the Z39.50 protocol. ZBroker samples the content of each bibliographic database by using training queries and …

Mpeg-4 Systems And Applications, Hari Kalva, Lai-Tee Cheok, Alexandros Eleftheriadis

Research Collection School Of Computing and Information Systems

MPEG-4, under the auspices of the ISO, is specifying tools to enable object-based audio-visual presentations [3]. These include tools to encode individual objects, compose presentations with objects, store these object-based presentations and access these presentations in a distributed manner over networks. The main distinguishing feature of object-based audio-visual presentations is the scene composition at the user terminal. The objects that are part of a scene are composed and displayed at the user end as opposed to encoding the composed scenes as is done in the case of MPEG-2. Such object-based representation and presentation has several benefits including compression efficiency and …

Marketing, Business Processes, And Shareholder Value: An Organizationally Embedded View Of Marketing Activities And The Discipline Of Marketing, Rajendra Kumar Srivastava, Tasadduq A. Shervani, Liam Fahey Oct 1999

Marketing, Business Processes, And Shareholder Value: An Organizationally Embedded View Of Marketing Activities And The Discipline Of Marketing, Rajendra Kumar Srivastava, Tasadduq A. Shervani, Liam Fahey

Research Collection Lee Kong Chian School Of Business

The authors develop a framework for understanding the integration of marketing with business processes and shareholder value. The framework redefines marketing phenomena as embedded in three core business processes that generate value for customers-product development management, supply chain management, and customer relationship management-which in turn creates shareholder value. Such a conceptualization of marketing has the potential to introduce dramatic shifts in the scope, content, and influence of marketing in the organization. The authors highlight the implications of an organizationally embedded view of marketing for the future of marketing theory and practice.

Design Approaches To Model-Based Simulation In Intelligent Computer Assisted Instruction, Bjoern Helfesrieder, Venky Shankararaman

Research Collection School Of Computing and Information Systems

Model-based simulation systems have been created in various fields of engineering to train personnel or students in operation, maintenance and troubleshooting of complex devices and systems. A review of literature indicates a lack of good overviews of the approaches to system design of model-based training simulations in Intelligent Computer Assisted Instruction (ICAI). Though single systems have to some extent been evaluated with regard to their performance, an organised evaluation, especially a comparative evaluation of the systems that have been created within the field is lacking. To be able to successfully conduct an in-depth review under these conditions, we concentrate and …

Locating Web Information Using Web Checkpoints, Aik Kee Luah, Wee-Keong Ng, Ee Peng Lim, Wee Peng Lee, Yinyan Cao

Research Collection School Of Computing and Information Systems

Conventional search engines locate information by letting users establish a single web checkpoint1. By specifying one or more keywords, users direct search engines to return a set of documents that contain those keywords. From the documents (links) returned by search engines, user proceed to further probe the WWW from there. Hence, these initial set of documents (contingent upon the occurrence of keyword(s)) serve as a web checkpoint. Generally, these links are numerous and may not result in much fruitful searches. By establishing multiple web checkpoints, a richer and controllable search procedure can be constructed to obtain more relevant Web information. …

Non-Repudiation In An Agent-Based E-Commerce System, Chin Chuan Liew, Wee-Keong Ng, Ee Peng Lim, Beng Suang Tan, Kok-Leong Ong Sep 1999

Non-Repudiation In An Agent-Based E-Commerce System, Chin Chuan Liew, Wee-Keong Ng, Ee Peng Lim, Beng Suang Tan, Kok-Leong Ong

Research Collection School Of Computing and Information Systems

Abecos is an agent-based e-commerce system under development at the Nanyang Technological University. A key factor in making this system usable in practice is strict security controls. One aspect of security is the provision of non-repudiation services. As protocols for non-repudiation have focused on -message non-repudiation, its adaptation to afford non-repudiation in a communication session for two agents in Abecos is inefficient. In this work, we investigate and propose a protocol for enforcing non-repudiation in a session. The protocol is believed to be applicable in any e-commerce system; agent- or not agent-based.

Artificial Intelligence Approach To Analyzing The Bullwhip Effect In Supply Chains, C. Qing, Keng Siau

Research Collection School Of Computing and Information Systems

Supply chain management critically affects businesses’ abilities to obtain and sustain competitive advantages. The bullwhip effect, however, presents a challenge for successful supply chain management by amplifying demands in the supply chains. This paper presents a systematic approach to tackle the issue of bullwhip effect. Firstly, we define the supply chain under a multiagent framework. Secondly, the group problem solving paradigm, which is a rule learning approach, is proposed to enhance the decision making process within the supply chain framework. The group problem solving paradigm is also suggested as a means to alleviate the bullwhip effect. The paper concludes with …

Knowledge Sharing With Customers On The Www: Approaches By National Tourism Organizations, Xinran You, Joseph O'Leary, Fiona Fui-Hoon Nah Aug 1999

Knowledge Sharing With Customers On The Www: Approaches By National Tourism Organizations, Xinran You, Joseph O'Leary, Fiona Fui-Hoon Nah

Research Collection School Of Computing and Information Systems

The importance of knowledge management has been emphasized increasingly in recent literature. Knowledge has been regarded as the most important corporate asset in an organization (Nonaka and Takeuchi, 1995). But what is knowledge? According to Harris (1996), "when information is combined with context and experience, it becomes knowledge". Hence, knowledge is the integration of information, context, and experience (Ponelis and Fairer-Wessels, 1998). In the tourism context of this paper, there are two components of knowledge: (1) customer knowledge--understanding of customers by marketers that leads to more effective marketing actions; and (2) destination knowledge that either the travelers or travel experts …

Cluster-Based Database Selection Techniques For Routing Bibliographic Queries, Jian Xu, Ee Peng Lim, Wee-Keong Ng

Research Collection School Of Computing and Information Systems

In this paper, we focus on the database selection problem in the context of a global digital library consisting of a large number of online bibliographic servers. Each server hosts a bibliographic database that contains bibliographic records each of which consists of text values for a number of pre-defined bibliographic attributes such as title, author, call number, subject, etc.. Each bibliographic database supports user queries on the bibliographic attributes. Since bibliographic records are relatively small in size, we only consider bibliographic databases that support boolean queries on the bibliographic attributes, and the query results are not ranked. While focusing on …

Experience As Art, Sor-Hoon Tan Jul 1999

Experience As Art, Sor-Hoon Tan

Research Collection School of Social Sciences

Chinese philosophy views experience as intrinsically aesthetic. This world view could be elucidated through a consideration of John Dewey's aesthetics and features of Chinese art. Dewey's philosophy of art starts with an understanding of experience as 'live processes' of living creatures interacting with their environment. Such processes are autopoietic in being self-sustaining, ever-changing, capable of increasing complexity, capable of generating novelty, direction and progress on its own. Its autopoietic character is a precondition of the aesthetic in the process of experience. An aesthetic experience is rhythmic, focused, consummatory, and reaches beyond the transitory boundaries of concrete existence. The aesthetic is …
