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 Internet has evolved into a ubiquitous communication medium which is used by Web-based communities to exchange information and to access remote services. In this context, on demand collaboration is mainly offered on the basis of separately executed browser-based applications which are inherently limited to be used online while offering a user interface to server-side applications. In this paper, we propose the use of the on demand Internet computing system (ODIX) which enables the distributed deployment and dynamic composition of Java rich Internet applications. It eases the integrated use of multiple applications and provides the illusion of a pervasive application environment by synchronizing user profiles and application customization across distinct Internet computing devices. The features of the approach are outlined and its application to support collaborative knowledge management is illustrated

If the full CRISP DM life-cycle is to be implemented then there needs to be a means by which business logic, understanding and aims can be directly related to the DM and KDD modelling process, and then onto deployment. Several graphical ways of representing data and models are considered: the E-R diagram, linked data and model ontologies, and graphical-model/Bayesian-net dependency diagrams. It is suggested that the provision of graphical tools for the domain expert to express their prior knowledge, understanding and aims is the best way of linking these to the DM & KDD process and subsequent deployment of discovered knowledge

This paper briefly reviews the recent literature on consistent query answering, an approach to handle database inconsistency in a systematic and logical manner based on the notion of repair. It discusses some computational and semantic limitations of consistent query answering, and summarizes selected research directions in this area.

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

In the era of information technology, almost all business data is stored and archived in electronic formats. 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. This research measures the data growth within the Kuwaiti banking sector on potential servers, like file-servers and email-servers, by analyzing historical data. Furthermore, it spots the light on the data growth within the client's machines in a well established Kuwaiti private company using online measurement mechanism

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

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

Efficient support of semantic location queries in distributed hash table (DHT) P2P systems is a key challenge. It is difficult to handle since object distribution criteria among data providers are not related to semantic criteria. This paper focus on range queries which are particularly expensive or impose strong restrictions in current proposals. We propose meta-data indexing to support queries involving inequalities and "like" operators in a scalable way. The proposed solution is portable, it can be used on top of any current DHT P2P system

The paper describes a dynamic integration mechanism for a virtual repository that transparently integrates distributed, heterogeneous and redundant resources. The repository is based on combination of a P2P network, object-oriented databases, a query language SBQL and virtual updateable views defined and used in SBQL. It is currently implemented as a prototype under .NET in C#. We also discuss a solution for an independent virtual P2P network integrating resources stored in databases and a novel global index mechanism
