Abstract

Within the looming threat of the combination of computer databases with monitoring and surveillance devices, attempts to define the notion of privacy and its parameters. Considers the ethical issues posed by databases, touching on disclosure to organizations of matters such as personal taxation and financial information or security surveillance. Highlights the increasing information imbalance between persons and organizations and suggests ways to improve autonomy

Abstract

Evaluates a range of commercially available software designed to act as intelligent search agents to assist users find materials of interest on the Internet and WWW or selects for them without asking. Notes that existing search engines can be useful in finding information but their different features and sometimes unfriendly interfaces can be confusing and intelligent search agents may be able to overcome these difficulties. Singles out one package: Autonomy; from Autonomy Corporation, describes its specific features and reports results of a test conducted with the software. Concludes that, from the test results, Autonomy is not yet ready to challenge the existing Internet search engines, which in the tests performed better than Autonomy with regard to recall and precision of information retrieval. Autonomy did not give enough feedback to control the search action

Abstract

Reviews the Autonomy intelligent search agent for the Internet. The system searches for Internet sites based on a description of the search problem, the user selects suitable documents and the search is retained using this selection. The evaluation indicates that Autonomy is not suited to ad hac one-off searches as it takes too long compared to more traditional search engines. Search agents could be used for monitoring the WWW, or searching newspapers

Abstract

We are in the midst of a new business revolution driven by information technology. The centerpiece of this business revolution is a new kind of product which delivers instant customer gratification in a cost-effective way. The ability to make such products will determine the successful corporations of the next century. The new business revolution demands drastic changes in organizational knowledge creation, among corporations as well as in a corporation. The key attributes of Japan's success in creation of organizational knowledge are: (1) participative management, (2) "Kaizen," and (3) "Keiretsu." In today's world of fast-moving markets and fierce competition, however, the Japan model betrays its weakness: too much time required for organizational decision making, difficulty to make revolutionary change, and obscurity of responsibility. To solve the problems, Japanese companies are decentralizing the organizations and forming virtual corporations. The changes from consensus management to responsibility management and from "keiretsu" groups to virtual corporations pose three fundamental challenges to Japanese corporations in organizational knowledge creation: (1) co-existence of firm central direction and maximum individual autonomy; (2) construction of sophisticated information networks; and (3) intercultural communication. Corporations, MITI, and universities in Japan are making concerted efforts to deal wich the winds of change that are sweeping through industry and the economy.

Abstract

Discusses a way of designing intelligent systems that assure autonomy, generality and practicality in problem solving to the greatest extent and can solve complex problems. There are various types of problem solving, depending on the object and often more than 1 subjects concern the same problem with different roles in complex problem solving. Discusses a new architecture for the system and a new modelling scheme for representing problems including human activity, as well as a way of generating problem-specific problem solving systems. New concepts include: a multi-level function structure and its corresponding knowledge structure, multiple meta-level operations and a multi-strata model to represent problems including human activity. The system realizes not only the generality but also the practicality of problem solving by enabling automatic programming

Abstract

Considers the 2 conflicting phenomena of disintermediation and information overload, which in the Internet era respectively pose a threat and offer an opportunity to the librarian and information science profession. User-orientated commercial products and services are tending to promote user information autonomy; but, more positively, the online electronic publication explosion has impelled librarians to cretae Net information resource catalogues, and the IT community to devise novel Internet access tools. Librarians will thus have a useful role to fulfil in both the free and fee-paying E-information sectors as cybrarians or information managers

Abstract

The IOS rererence model of open distributed processing (RM-ODP) consists of: an overview of the reference model, the descriptive model, the prescriptive model, and the architectural semantics. They provide the concepts and rules of distributed processing to ensure openness between interacting distributed application components. Openness is a combination of characteristics: accessibility, heterogeneity, autonomy and distribution. The RM-ODP introduces the concept of viewpoint to describe a system from a particular set of concerns, and hence to deal with the complexity of distributed systems. While all the viewpoints are relevant to the description and design of distributed systems, the computational and engineering models are the ones that bear most directly on the design and implementation of distributed systems. From a distributes software engineering point of view, the computational and engineering viewpoints are again the most important; they reflect the software structure of the distributed application most closely. Concentrates on the computational and engineering viewpoints

Abstract

Semantic integration and data integration are 2 main processes that multidatabase systems need to employ in order to support interoperability. Both these processes involve uncertainty when attribute correspondences and global IDs are unknown or imprecise. The role-set approach is a new conceptual framework for data integration in multidatabase systems that maintains the materialization autonomy of local database systems by presenting the answer to a query as a set of sets representing the ddistinct intersections between the relations corresponding to the various roles played by an entity. In this article, we present an approach for dynamic database integration and query processing in the absence of information about attribute correspondences and global IDs. We define different types of equivalence conditions for the construction of global IDs. We propose a strategy based on ranked role-sets that makes use of an automated semantic integration procedure based on neural networks to determine candidate global IDs. The data integration and query processing stepts then produce a number a role-sets, ranked by the similarity of the candidate IDs

Abstract

Contemporary studies of information and documentation focus on 3 dimensions: the theoretical, i.e. the sciences of interpretation of text; the practical, i.e. the impact of new technology on systems of inscription; and the political, i.e. the consequent proceses of social identification and cultural autonomy. Documentation languages provide rules for transforming items of information into documentation products, and the process of information analysis fixes meaning by applying such rules in the context of collective experience. Information transfer and communication thus depends on a communicational contract setting out the parameters for negotiating meaning. This requires the information analyst and other professionals to discuss the rules of the information game openly with external participants, as the necessary condition for a democratic and equitable science of information
