In this paper, we provide an evaluation model for marketable quality and profitability of corporations. We apply the real values of some leading manufacturing corporations in Japan to our proposed model to analyze its accuracy. From the analysis, we concluded that the theoretical and real standard values of the marketable quality indicator were both 0.6 (that is 60%). From our further analysis, we extracted the turning point from economies of scale to enhancement of marketable quality. The turning point is almost the same with the theoretical standard values of marketable quality and the rate of operation

The effective grouping, or partitioning, of semistructured data is of fundamental importance when providing support for queries. Partitions allow items within the data set that share common structural properties to be identified efficiently. This allows queries that make use of these properties, such as branching path expressions, to be accelerated. Here, we evaluate the effectiveness of several partitioning techniques by establishing the number of partitions that each scheme can identify over a given data set. In particular, we explore the use of parameterised indexes, based upon the notion of forward and backward bisimilarity, as a means of partitioning semistructured data; demonstrating that even restricted instances of such indexes can be used to identify the majority of relevant partitions in the data

Internet should be used to reduce distances and bring people virtually closer. Using ICT, many people has overcome the problem of digital divided (P. Norris, 2001) thanks to support of information system technologies, (e.g. email, wiky, community, Web-log, video streaming). Nowadays the communications between people using ICT hasn't a structure able to implement a rich and efficient use of information such as datum. Most of the knowledge management systems for complex organizations are based on technological architectures that are in contradiction with the social processes of information like human language. In particular, centralized architectures are adopted for to manage a process that is intrinsically distributed, such "experience". In this paper, we introduce the concept of SEA, an example of (DKM) distribute knowledge management (M. Bonifacio et al., 2002) architecture as example of an extendable and scalable system architecture for knowledge management
互联网应该用来缩短距离，拉近人与人之间的距离。利用信息通信技术，许多人克服了数字鸿沟的问题(P. Norris, 2001)，这要感谢信息系统技术的支持，(如电子邮件、维基、社区、网络日志、视频流)。目前，使用ICT的人们之间的通信还没有一个能够实现对数据等信息的丰富和有效利用的结构。大多数复杂组织的知识管理系统都是基于与人类语言等信息的社会过程相矛盾的技术架构。特别地，集中式架构被用于管理本质上是分布式的过程，例如“体验”。在本文中，我们介绍了SEA的概念，它是(DKM)分布式知识管理(M. Bonifacio et al.， 2002)体系结构的一个例子，作为知识管理的可扩展和可伸缩的系统体系结构的一个例子

The advent of electronic media enabling rapid publishing and instant access to news articles has vastly increased the working pace of the media industry. Press agencies can no longer afford to neglect plagiarisms formerly perceived as irrelevant because such acts instantly void the commercial value of original and potentially exclusive news articles. From a different point of view, individuals and organizations of public interest require instant evaluation of impact of actions taken and diffusion of statements made in the media. This publication presents a methodology and a prototypical system for analyzing plagiarisms and, in general, diffusion of textual content in newspaper articles and reports on preliminary application results obtained in the context of Austria's press agency APA

Replication increases the availability of data. Availability, consistency and integrity are competing objectives. They need to be reconciled, and adapted to the needs of different applications and users, by appropriate replication strategies. We outline work in progress on a middleware architecture for replicated databases. It simultaneously maintains several protocols, so that it can be reconfigured on the fly to the actual needs of availability, consistency and integrity of possibly simultaneous applications and users

Middleware-based data replication is a way to increase availability, fault tolerance and performance of networked information systems without modifying the underlying DBMS core code. However, if such middleware is not properly conceived, it will introduce an overhead leading to poor response times. In this paper, we study the progression of solutions for problems typically entailed by replication, which led to the use of middleware for avoiding inconveniencies associated with earlier approaches. We survey several existing and projected architectures - designed by our research groups - in terms of availability, consistency and fault tolerance

Web services and service oriented architectures present a new approach to application integration. While it is reasonable inside an enterprise, it has certain deficiencies when applied in a B2B environment. These deficiencies apply to the discovery, invocation and composition phases, which require considerable manual effort. In the paper, we show on example of a mortgage simulator how these deficiencies can be overcome by applying semantic Web services. The application is compatible with the Web services modelling ontology and makes use of an execution environment automating the processes of discovery, composition and invocation of semantic Web services, enabling faster and cheaper B2B application integration

Both the easiness of the electronic storing methods and the low prices of the storing devices have encouraged a great data growth within nowadays organizations.

The notion of a self-organising system as used within this paper, is of a system that optimises and adapts its architectural composition based on evidence accrued from both internal and external influences. In this way, a self-organising system is defined to be a fluid, unbounded set of components that are organised and configured on demand and at runtime in reaction to the current configuration of the system's operating environment. This paper outlines current theory and assumption in component-based self-organisation, discussing the limitations that exist when producing such systems. The paper highlights, through example, how the introduction of type-safety at a network layer aided by Zeroconf (zero configuration networking) and the author's own Neptune language can yield a powerful self-organisational model, concluding with its use within a healthcare agenda system
