An analysis of knowledge base maintenance
Knowledge base maintenance is managed by constructing a formal model. In this model the representation of each chunk of knowledge encapsulates the knowledge in a set of declarative rules, each of which in turn encapsulates the knowledge in a set of imperative programs. In this model an “item” is the unit of knowledge representation. Items are at a higher level of abstraction than rules. Underst...
متن کاملKnowledge Base Maintenance through Knowledge Representation
The problem of maintaining a knowledge base is substantially concerned with keeping track of rules that share common wisdom. A knowledge representation is described in which a collection of rules that are based on common wisdom are represented as a single ‘item’. For items, maintenance hazards, caused by one item being partially hidden within another, still remain. ‘Objects’ are introduced as i...
متن کاملEngineering Experience Base Maintenance Knowledge
The value of a corporate information system such as an experience base tends to degrade with time. To keep the value of such a system, maintenance is an essential. Maintenance should not simply happen ad-hoc but systematically and based on specific maintenance knowledge. As a jump-start for maintenance, maintenance knowledge should be available right from the start of continuous operation. This...
متن کاملan infinite planar array of rectangular microstrip patch antenna analysis
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
15 صفحه اولA Rigorous Approach to Knowledge Base Maintenance
A knowledge base is maintained by modifying its conceptual model and by using those modifications to specify changes to its implementation. The maintenance problem is to determine which parts of that model should be checked for correctness in response a change in the application. The maintenance problem is not computable for first-order knowledge bases. Two things in the conceptual model are jo...
