Whenever a technical task is to be solved with the help of a database application and uncertainties regarding the structure, scope or level of detail of the data model exist (either currently or in the future) the use of a generic database application can reduce considerably the cost of implementation and maintenance. Simultaneously the approach described in this contribution permits the operat...

High-level semantics such as “mood” and “usage” are very useful in music retrieval and recommendation but they are normally hard to acquire. Can we predict them from a cloud of social tags? We propose a semantic identification and reasoning method: Given a music taxonomy system, we map it to an ontology’s terminology, map its finite set of terms to the ontology’s assertional axioms, and then ma...

Abstract Background and Aim: One of the major problems with resin composite restorations is the weakness of bonding between the new and aged composites. Since appropriate micromechanical retention is necessary for the repair of aged resin composite restorations, the level of surface roughness after sandblasting can be influential in this regard. Considering the diverse composition of avail...

BACKGROUND AND OBJECTIVES To correlate standard base excess (SBE) with serum lactate level and demonstrate the independent prognostic significance of each one. METHODS In a retrospective study, we retrieved data from 333 patients of our prospectively collected database of 7-bed medical intensive care unit of a 1800-bed university hospital. RESULTS The results have shown a poor correlation b...

The paper starts with a discussion of the roles an organizational memory (OM) should play and what kind of knowledge should go into it. We then identify two kinds of integration problems. The rst one is concerned with integrating the knowledge bases of diierent knowledge-based systems employed in an organization into one physically or virtually uniied knowledge base which is to be considered as...

in this paper, we discuss use of knowledge and knowledge base approach in content based image retrieval. Appling knowledge base method in content base image retrieval system, we target semantic gap between actual result and human perception as per query. Knowledge base technology has become an established technology. Different requirements count nowadays when developing knowledgebased solutions...

in this paper, the problem of determining the quality level, lead time for order delivery and price of a product produced by a manufacturer is considered. in this problem the demand for the product is influenced by all three decision variables: price, lead time and quality level. to formulate the demand function, a fuzzy rule base that estimates the demand value based on the three decision vari...
