Knowledge bases are encountered in different AI areas such as configuration, planning, diagnosis, semantic web, game playing, and others. Very often the amount and arrangement of the elements in the knowledge base outstrips the capability of a knowledge engineer to survey them and to efficiently perform maintenance operations – a situation that triggers an enormous demand of extending and impro...

The development of highly effective heuristics for search problems is a difficult and time-consuming task. We present a knowledge acquisition approach to incrementally model expert search processes. Our approach targets at the implicit representation of the less clearly definable quality criteria by allowing the expert to limit their input to the system to explanations of the steps in the exper...

Most knowledge-based system development efforts include acquiring knowledge from one or more sources. Difficulties associated with this knowledge acquisition task are readily acknowledged by most researchers. While a variety of knowledge acquisition methods have been reported, little has been done to organize those different methods and to suggest how to apply them within a conceptual framework...

In recent years, knowledge-based systems have become one of the most popular approaches for solving engineering problems. Along with the rising complexity of the problem, knowledge management, acquisition, representation, inferencing, and refinement become increasingly difficult. Conventionally, tasks of knowledge acquisition and representation are accomplished separately and sequentially. Know...

a recent international journal of health policy and management (ijhpm) article by fadi el-jardali and colleagues makes an important contribution to the literature on health system strengthening by reporting on a survey of healthcare stakeholders in low- and middle-income countries (lmics) about systems thinking (st). the study’s main contributions are its confirmation that healthcare stakeholde...

We know a lot. I know what food penguins eat. I know that phones used to ring, but nowadays squeal, when someone calls up. I know that Essendon won the 1993 Grand Final. I know that here is a hand, and here is another. We have all sorts of everyday knowledge, and we have it in abundance. To doubt that would be absurd. At any rate, to doubt it in any serious and lasting way would be absurd; and ...

Knowledge-based knowledge management (KBKM) focuses on applications of knowledge-based systems (KBS) tailored to knowledge management (KM) problems. Although KM is primarily concerned with how people and organizations utilize their knowledge assets, one key to doing so efficiently is to employ technology to facilitate the KM process. One particular kind of technology has shown itself to be extr...
