background: evidence-based practice (ebp) is one of the main professional competencies for health care professionals and a priority for medicine and nursing curriculum as well. ebp leads to improve effective and efficient care and patient outcomes. nurse educators have responsibility to teach the future nurses, and an opportunity to promote patient outcomes. therefore, the aim of this study was...

A definitional approach to the construction of knowledge-based systems is presented. The notions of a knowledge base and the logical interface of a knowledge base are discussed.

Evaluation of knowledge acquisition (KA) technology is difficult because of the costs of using human expertise in experimental studies. An analysis of the types of errors a human expert makes in building a knowledge-based system (KBS) has been developed which suggests that a simulation of the key factors in building a KBS is possible. A demonstration KA simulation has been implemented for one K...

This article presents methods for modeling knowledge base and database for intelligent concurrent design, including mathematical formulation and system development. Four issues are addressed in this research: (1) modeling product life-cycle aspects using aspect primitives called features, (2) generating product life-cycle aspects using a knowledge-based system, (3) maintaining consistency of pr...

Our goal is to build knowledge acquisition tools that support users in modifying knowledge-based systems. These modi cations may require several individual changes to various components of the knowledge base, which need to be carefully coordinated to prevent users from leaving the knowledge-based system in an unusable state. This paper describes an approach to building knowledge acquisition too...

Personalized knowledge-based systems have not yet become widespread, despite their potential for valuable assistance in many daily tasks. This is due, in part, to the high cost of developing and maintaining customized knowledge bases. The construction of personal assistants as learning apprentices -interactive assistants that learn continually from their users -is one approach which could drama...

Many knowledge-based systems feature general machinery that operates on externally supplied information, These systems must solve the acquisition problem: how to represent the external knowledge, determine if it is adequate, and incorporate it into the knowledge base. As a mediator between users and interactive services, the Consul system must understand the intent and behavior of programs that...

since the 1970s, services marketing has grown into a major sub discipline of marketing. it is constantly claimed – but is refuted in the article – that services are now the dominant economic activity in developed countries and keeps growing while the two traditional goods sectors, manufacturing and agriculture, are declining. in today's competitive world, having expertise, knowledge and ma...

Libraries in India are striving to provide necessary and relevant information to their users. Limited resources have been one main barrier to satisfying the growing informational needs of the users. Now, the Indian libraries are planning various methods of resource sharing to help meet information demands. Attitudes of library and institutional managements have undergone a change, to become mor...
