This work examines the interplay of inter-personal and inter-organizational trust, two distinct but related concepts, through a theoretic inter-organizational trust-based security model for a multi-agent system information-sharing community. A calculus that mathematically models trust building at the inter-organizational level is at the heart of this model. In inter-organizational or inter-firm exchange, the role of the boundary spanner, an organizational representative, is important in reducing asymmetries that may exist between the two parties. Trust is a crucial component to the dyadic interaction at the inter-personal or boundary spanner level, and the trust established at this level also affects the overall quality of the relationship at the inter-organizational level. Trust, as an aspect of social control, is thus viewed as a more effective mechanism for security in an open, distributed system, like an information-sharing community. The inter-organizational trust-based security model proposed herein represents a soft security approach. It affords several important benefits over traditional hard security mechanisms used in open systems — robustness, scalability, and adaptability. The inter-organizational trust-based model is an important contribution to the computational security community, as other open systems applications of a distributed or pervasive nature could adapt it and realize its benefits. It is also one of a few attempts to model trust building at either the inter-organizational or inter-personal level.
This article reviews formal systems that regulate persuasion dialogues. In such dialogues two or more participants aim to resolve a difference of opinion, each trying to persuade the other participants to adopt their point of view. Systems for persuasion dialogue have found application in various fields of computer science, such as non-monotonic logic, artificial intelligence and law, multi-agent systems, intelligent tutoring and computer-supported collaborative argumentation. Taking a game-theoretic view on dialogue systems, this review proposes a formal specification of the main elements of dialogue systems for persuasion and then uses it to critically review some of the main formal systems for persuasion. The focus of this review will be on regulating the interaction between agents rather than on the design and behaviour of individual agents within a dialogue.
Within the broad field of spoken dialogue systems, the application of machine-learning approaches to dialogue management strategy design is a rapidly growing research area. The main motivation is the hope of building systems that learn through trial-and-error interaction what constitutes a good dialogue strategy. Training of such systems could in theory be done using human users or using corpora of human–computer dialogue, but in practice the typically vast space of possible dialogue states and strategies cannot be explored without the use of automatic user simulation tools.
This requirement for training statistical dialogue models has created an interesting new application area for predictive statistical user modelling and a variety of different techniques for simulating user behaviour have been presented in the literature ranging from simple Markov models to Bayesian networks. The development of reliable user simulation tools is critical to further progress on automatic dialogue management design but it holds many challenges, some of which have been encountered in other areas of current research on statistical user modelling, such as the problem of ‘concept drift’, the problem of combining content-based and collaboration-based modelling techniques, and user model evaluation. The latter topic is of particular interest, because simulation-based learning is currently one of the few applications of statistical user modelling that employs both direct ‘accuracy-based’ and indirect ‘utility-based’ evaluation techniques.
In this paper, we briefly summarize the role of the dialogue manager in a spoken dialogue system, give a short introduction to reinforcement-learning of dialogue management strategies and review the literature on user modelling for simulation-based strategy learning. We further describe recent work on user model evaluation and discuss some of the current research issues in simulation-based learning from a user modelling perspective.
The new millennium coincided with an explosion in the use of the Internet for commercial purposes. Dot.com companies in the United States such as Amazon and eBay led the way, creating online services where none had existed before. Recognizing the value of e-commerce, traditional companies also jumped online, including Wal-Mart in retail, Cisco in networking, Dell in the PC industry, and Charles Schwab in banking. In just a few short years, a company without a website was considered passé and the Internet was becoming mythologized: “A few years from now business economists may include the Internet in the Schumpeterian Hall of Fame, as an economic innovation of the same magnitude as the steam engine and the assembly lines of yore” (DePrince Jr. & Ford, 1999). Radical changes toward online business models were widely believed to be ushering in a “new economy” requiring new competitive strategies, business models, and even a new economics.
Given the major role played by the United States in developing the Internet and fostering its commercialization, other nations voiced concern that it would dominate e-commerce, spreading US culture and economic influence via electronic networks. The Internet compresses time and space, making it easier for companies to expand beyond regional boundaries. Commerce emerges as a powerful force beyond the control of individual countries, with a corollary being that the relevance of differences between countries diminishes. Taking this argument to the extreme, some predicted the emergence of a borderless global economy.
Taiwan has a hybrid economy that exhibits characteristics of both developed and developing economies. It has a highly developed and modern manufacturing sector, with linkages to customers throughout the world, and its companies are world leaders in the production of computers and other electronic products. Taiwan's literacy rate is comparable to mature economies, and it has a large base of technically skilled workers. Yet, the legal framework for e-commerce is developing only slowly and the rate of IT spending is relatively low, given the level of development. The result is that the Internet and e-commerce have progressed on two distinct trajectories: one for globally oriented manufacturing firms, and the other for firms selling to local consumers. The former utilize business-to-business e-commerce technologies to coordinate with global trading partners, while the latter have developed business-to-consumer strategies tailored to the preferences and buying habits of Taiwanese consumers.
The most important drivers of e-commerce use for manufacturers in Taiwan appear to be international competitive pressure and the requirements of global customers. In contrast, the retail/wholesale sector has a high density of physical retailers, is not subject to a great deal of pressure from foreign competition, and thus lags behind manufacturing in its use of the Internet and e-commerce. For Taiwanese firms, e-commerce adoption is typically undertaken either to broaden their customer base by exploring new marketing channels or to create competition for traditional channels.
In recent years globalization has become the subject of fervent debate, intensified by the spread of low-cost information and communications technologies (ICTs), particularly the Internet. On the one hand, crossborder flows of capital, labor, and information may be leading to convergence in how economic activities are organized, reducing the role of the state and its ability to control and guide its own economic development. There are fears that globalization is causing serious economic dislocation as competition intensifies and trade imbalances grow. On the other hand, culture, history, regulation, and other local factors may limit economic convergence, preserving national differences and creating unique capabilities and comparative advantages.
The spread of low-cost ICTs, particularly the Internet, accelerates the convergence process by facilitating cross-border information flows and coordination of economic activities. Excitement about the Internet's potential for improving quality of life and bolstering overall economic health is, however, tempered by concern over its potential for worsening the perceived threats of globalization.
The United States has played a key role in developing Internet technologies and applying them to create new models of e-commerce – uses of the Internet for business activities such as buying, selling, and providing support for products and services in the firm's value chain. US firms have been supported in these efforts by favorable government policies, a largely deregulated telecommunications market, a dynamic venture capital market, and positive attitudes toward information technology. US companies have used the Internet to create new businesses, transform old ones, and coordinate global production networks.
E-commerce in the United States has been shaped by the economic, social, and policy environment in which it developed, and in particular by the unique business patterns of the US high-tech industry sector. Many key e-commerce technologies and business processes were developed in the United States and the so-called Silicon Valley model – venture capital funding, entrepreneurial start-ups and spin-offs, and close ties to university research (e.g., Kenney, 2003) – has been the locus of much of the investment, innovation, hype, and despair associated with Internet-based e-commerce. Firms in the Silicon Valley model include many survivors of the dot.com era that are leaders in highly visible segments of B2C e-commerce, such as book and music retailing, online auctions, web portals, travel services, and online stock trading.
But the Silicon Valley model is only one dimension of a rich and complex pattern of e-commerce diffusion in the USA. A much larger share of e-commerce activity is characterized by a pattern we call “adaptive integration,” whereby existing firms incorporate the new technologies and business models offered by the Internet to extend or revamp their existing strategies, operations, and supply and distribution channels. Adaptive integration is the dominant pattern for business-to-business e-commerce in most major industries, including manufacturing, wholesale trade, banking, insurance, and transportation, and B2B dominates B2C e-commerce by far.
The Internet and e-commerce are recent examples of ongoing information technology innovations credited with driving the productivity revival of the past decade. Established firms such as Dell, Cisco, General Electric, IBM, and Wal-Mart, along with firms “born on the Internet,” such as Amazon and eBay, have shown the potential of IT and e-commerce to enhance customer services, streamline internal operations, and improve B2B coordination. Today, Internet use is almost universal among firms in the industrialized countries, and is growing rapidly in the developing world as well. Thus, there is global convergence in the continuing trend toward e-commerce diffusion.
Yet, technology diffusion is rarely a smooth and linear process. Many firms fail to achieve deep usage beyond initial adoption. Prior studies show that an e-commerce innovation must be integrated into a firm's value chain before it can generate significant business value. Ecommerce integration encompasses using the Internet for selling, buying, and coordinating both internal and external business processes. We would expect firms that are more advanced – that integrate the Internet most extensively – would reap the greatest benefits. And because firms in developed and developing countries may be at different stages of the diffusion process, we would expect there to be divergence in the relative importance of the factors that influence each stage.
Indeed, as with the earlier chapters in this book, we find that there is both global convergence and local divergence in e-commerce diffusion.
After implementing a comprehensive economic liberalization program in the 1990s, Mexico has become one of the most open economies to foreign trade and investment, and has positioned itself among the ten largest economies in the world. The resulting substantial integration into the global economy has created both the conditions and the pressures for the business community in Mexico to adopt the Internet to improve coordination, expand markets, and cut costs to face a highly competitive environment in both national and international markets. Mexico has long been a major production platform for subsidiaries of numerous multinational corporations (MNCs), many of which operate as maquiladoras, a situation reinforced as it has become increasingly engaged in international trade. Those MNC subsidiaries, along with a small but growing echelon of internationally oriented domestic companies, account for a large share of the country's total exports, and are the most dynamic and technologically advanced business establishments in the Mexican economy. Accordingly, they have led in the use of information and communication technologies (ICTs) for commercial purposes.
Major improvements in the country's telecommunications infrastructure since the mid-1990s have facilitated and spurred the use of both personal computers and the Internet. Economic liberalization, along with aggressive promotion campaigns by trade and industry associations, have further paved the way for the adoption of e-commerce by large and small, domestic and foreign enterprises. This has occurred particularly in finance, distribution, and manufacturing, and largely in the country's main industrial hubs (Guadalajara, Monterrey, and Mexico City).
The French-specific path for e-commerce is shaped by the characteristics of the country's economy and innovation system. The French national system of innovation is led by large established firms that are not well adapted to the decentralized process of innovation at the heart of the Internet revolution. This has hindered the development of e-commerce as innovation has occurred only in industries where dominant firms were driven to go online in response to national and international competition. Also, the central government used to play a powerful role in the economy, and has more influence over technology adoption choices than in other countries.
As a result, technologies tend to be widely adopted only when supported by big companies, as in the case of EDI, or by government, as in the case of videotext. France was an early adopter of e-commerce in the 1980s in both the business-to-business and the business-to-consumer segments based on EDI and videotext (marketed as Minitel) technologies, respectively (Brousseau, 2001, 2003; Brousseau & Kraemer, 2003). As a result, when the Internet became available for commercial application in the mid-1990s, French consumers and firms did not perceive it to be advantageous compared with existing technologies, delaying adoption of Internet-based e-commerce.
The diffusion of Internet-based e-commerce was inhibited by the adoption of these earlier technologies and the switching costs associated with moving to Internet-based options. Also, the presence of efficient physical distribution channels limited the adoption of online shopping.
Japan is characterized by a unique industrial landscape, including interlocking networks of firms (keiretsu), a highly interwoven political economy (iron triangle), and a distinctive business culture. The combination of these factors leads to a somewhat insular business environment, as indicated by globalization measures uniformly below the global average of firms in the GEC database. Despite the importance of globalization to innovation, Japan is comparable with other economies along the various e-commerce usage measures contained in the global sample. However, Japan lags far behind in achieving some of the key benefits associated with Internet adoption, such as increased sales and reduced procurement costs. Japan thus illustrates the salience of local factors in the adaptation of new technologies such as e-commerce within national environments. In contrast to the notion of the Internet and e-commerce driving a borderless global economy, Japan illustrates that characteristics of the national economy may be reinforced by the use of the Internet and e-commerce, and not be muted by the global melting pot.
Japanese firms have made great strides in adopting a wide variety of e-commerce technologies. Together with adaptation of proven models such as the Silicon Valley model in Tokyo's Bit Valley, ecommerce emerges as an important, though not necessarily transformational, technology enabling operational efficiencies along industry supply chains. However, the level of information systems spending is modest compared with the average firm in the global sample. This has led to the idea that Japanese companies lag in getting online.
