Agriculture is the dominant sector in the Ethiopian economy but it is characterized by low productivity. Ethiopia is interested in creating access to agricultural knowledge through an agricultural knowledge management system (AKMS). Such a system has been developed using a web-based portal named Ethiopian Agriculture Portal (EAP). It is facilitated through Woreda Knowledge Centers (WKCs) which ...

Knowledge bases constitute the core of those Artificial Intelligence programs which have come to be known as Expert Systems. An examination of the most dominant knowledge representation schemes used in these systems reveals that a knowledge base can, and possibly should, be described at several levels using different schemes, including those traditionally used in operational databases. This cha...

Cooperative problem solving systems support the solution of tasks which cannot be solved by the human or the computer alone. These systems need to be knowledge-based and require flexible communication paradigms allowing natural communication with both experts and novice users of the system. Natural communication (quite dtfferent from natural language) has to support mixed-initiative dialogues w...

Research led by Professor Chapman at the Knowledge Based Engineering (KBE) lab has resulted in a thriving partnership with the aerospace division of Rolls-Royce. KBE research captures domain-based knowledge and integrates it into refined computational models with automated tools to enhance design processes for engineering complex systems. This research has contributed to important improvements ...

s of Recent Technical Reports INTERACTIVE CLASSIFICATION A Technique for the Aquisition and Maintenance of Knowledge Bases, Tim Flnln and David Silverman, MS-CIS-84-17. The practical application of flame-based knowledge-based systems, such as in expert systems, requires the maintenance of potentially very large amounts of declarative knowledge stored in their knowledge bases (KBs). As a KB grow...

The MICON Synthesizer Version 1 (M1) is a rule-based system which produces a complete small computer design from a set of abstract specifications. The ability of M1 to produce designs depends on the encoding of large amounts of domain knowledge. An automated knowledge acquisition tool, CGEN, works symbiotically with M1 by gathering the knowledge required by M1. CGEN acquires knowledge about how...

In this paper, the development of knowledge management (KM) was surveyed, using a literature review and classification of articles from 1995 to 2004. With a keyword index and article abstract, we explored how KM performance evaluation has developed during this period. Based on a scope of 108 articles from 80 academic KM journals (retrieved from six online databases), we surveyed and classified ...

The goal of this paper is to provide a fundamental methodical approach for identifying actors in Complex Adaptive Logistics Systems to deduce knowledge that can be implemented into the decision structures of intelligent logistics objects. This serves as a basis for further simulation-based studies regarding the efficiency of the usage of autonomous cooperation-based technologies in logistics se...

How does someone react when he faces a critical situation in his life? In this paper we present an initial initial implementation architecture based on a simulation model described in [10] In our model we mainly consider the interactions between a person concerned and factors like his environment and his own abilities. Using the empolis information access suite, we currently implement our model...
