Ontological knowledge management system development

Abstract

The paper describes approach to development of enterprise knowledge management system. The main approach feature is active ontology using on evaluation stage while choosing knowledge management strategy and software developing. There i s a stage of basic knowtedge domain extraction by asking authorities and leading experts. This step is executed before ontology development. Company portal based on semantic technologies is proposedto use as the main software K M S tool. MTRODUCIIONToday knowledge is recognized as one the most important enterprise resources. Companies have to makes systematic purposeful work with all kinds of knowledge to achieve success. It's mean they have to execute knowledge management.Knowledge management is complicated process, involving creating of necessary condition (corporate culture, managerial procedure, software environment).These arrangements are makes to improve quality o f knowledge processes.It is necessary to build knowledge management system (KMS) for realizing particular work style. KMS include two main parts: organizational procedures and software.This paper propos new approach in K M S development and building which i s based on active ontology involving.An ontology is an explicit specification of a conceptualization 111. It invohes a set of concepts and different relations betweens them. Ontology alfows to make company knowledge more structured, to create "enterprise knowledge space" and to systematize working with knowledge.In enterprise KMS, ontology specifications can refer to taxonomies of the tasks that define the knowledge for the system. Ontologies define the shared vocabulary used in the K M S to facilitate communication, search, storage, and representation. Development and maintenance of an enterprise-wide ontology requires continual effort to evolve the ontology over time.Today there are many ways to define strategy of knowledge management developing [2-4]. However, we had come across with lack of real working approach to audit performing, strategy choosing and designing. This fact induced us to make own approach.This approach supposes that knowledge and knowledge processing system there are in a company.Organizational knowledge is held both "subjectively" in the mind of individuals and groups, and "objectively" in record and expressed form. We have to solve three basic tasks to make KMS development possible:1. An identification of main enterprise knowledge domains and existing knowledge process. Knowledge domain is the content of a particular domain or field of knowledge. An it include such tasks as:a. An identification of main knowledge domains b. An informational audit c. An personal audit d. An identification of existing knowledge processes 2. Forming strategy of knowledge management, it means defining a basic set of organizational and software tools which have to be used first.3. Implementation and deployment the chosen set of tools; at the same time we mean that main software tool is semantic based portal. COMPANY KNOWLEDGE DOMAINS IDENTlFiCATIONThe basic too!...

Architecture of Enterprise Information Systems Based on the Semantic Web Technologies

“…Active development of the Semantic Web technologies started under guidance of the W3С [1] in late 90s with the intention to create new generation of the World Wide Web. The technologies include numerous interlinked standards which are usually presented as a stack [2,3] shown in Fig. 1.…”

Using Knowledge Management Systems to Enhance Cooperative Learning

“…For the main purpose of using knowledge management systems is to gather knowledge, use, and recycling knowledge to be organized by the problems faced by the thereby increasing work efficiency [14]. In the knowledge management issues, not all of the knowledge management is supported in the information technology (IT), but the information technology (IT) is effective for knowledge management success factors [9].…”

A Novel Information Organization Method Based on Ontology for Unstructured Information

“…We present a framework based on [3] and [6]. In the paper, when taking measures to construct the unstructured information system, we will face some problems such as how to organize, discover, utilize, and manage the information resources.…”
