mln recent years, knowledge-based systems have become one of the most popular approaches for solving engineering problems. Conventionally, knowledge acquisition and representation are treated as separate processes. Knowledge engineers are responsible for preparing question patterns and setting up personnel interviews with domain experts for knowledge acquisition. All acquired knowledge is manua...

Knowledge of regulation relations is widely applied by biomedical researchers in for example experiment design on regulatory pathways and in systems biology. In the work presented here, we analyze in total 28 verbs and in dept 6 frequently used verbs denoting the regulation relations regulates, positively regulates and negatively regulates through corpus analysis. We propose a formal representa...

Hierarchical phrase alignment is a method for extracting equivalent phrases from bilingual sentences, even though they belong to different language families. The method automatically extracts transfer knowledge from about 125K English and Japanese bilingual sentences and then applies it to a pattern-based MT system. The translation quality is then evaluated. The knowledge needs to be cleaned, s...

Complex real world domains can be characterized by a large amount of data, their interactions and that the knowledge must often be related to concrete problems. Therefore, the available descriptions of real world domains do not easily lend themselves to an adequate representation. The knowledge which is relevant for solving a given problem must be extracted from such descriptions with the help ...

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...

This paper deals with an interface between expert knowledge and group of experts from whom this knowledge has been acquired and who are going to be users of it. Method is based on deriving the most supported opinion of the group of experts acting as knowledge sources with further applying of it as an interface to each of experts acting as user. Knowledge is acquired using three-valued voting-ty...

Communication provides an access to a huge amount of information. By communication one may largely surpass the knowledge individually acquired by benefiting from the knowledge acquired by others. However, communication entails a risk of manipulation. Our speaker may want us to act in such way that will satisfy his desires. In particular, he may voluntarily provide us with misleading information...
