The dramatic explosion of internet information sources that become available to an exponentially growing number of users necessitates new strategies for navigating through the content space. This paper proposes an innovative architecture for an interactive information retrieval system which differs from common architectures for its unique knowledge representation which integrates syntactical an...

We consider the application setting where a domain-specific knowledge base about Durum Wheat has been constructed by knowledge engineers who are not experts in the domain. This knowledge base is prone to inconsistencies and incompleteness. The goal of this work is to show how the state of the art knowledge representation formalism called Datalog± can be used to cope with such problems by (1) pr...

in current century, success of organizations is dependent on the correct management of knowledge and also knowledge management (km) successful implementation relies on its critical success factors (csfs). identifying these critical factors can help businesses in planning and implementing knowledge management. hence, this study aims to propose a conceptual model with the csfs approach in order t...

The paper presents the concept of a system for intellectual digital e-university future (IDEUF) based on an integrated database that ensures correct function whole university system. Particular attention is paid to process checking students’ required and current level acquired knowledge, which considered one main parts educational process. article provides detailed comparative analysis actual t...

Often the users of a semantic search application are facing the problem that they do not find appropriate terms for their search. This holds especially if the data to be searched is from a technical field in which the user does not have expertise. In order to support the user finding the results he seeks, we developed a domainspecific ontology and implemented it into a search application. The o...

Designing KBS for dynamic environments requires the consideration of temporal knowledge reasoning and representation (TRR) issues. Although humans present a natural ability to deal with knowledge about time and events, the codification and use of such knowledge in information systems still pose many problems. Hence, the development of applications strongly based on temporal reasoning remains an...

This paper represents a step toward a theory of knowledge reusability, with emphasis on knowledge management systems and repositories, often called organizational memory systems. Synthesis of evidence from a wide variety of sources suggests four distinct types of knowledge reuse situations according to the knowledge reuser and the purpose of knowledge reuse. The types involve shared work produc...
