It is well known that "knowledge engineering" is necessary to represent experts' knowledge on computers.
As is well known, the Knowledge Base (KB) of an FES is composed of two components, a Data Base (DB), containing the definitions of the scaling factors and the membership functions of the fuzzy sets specifying the meaning of the linguistic terms, and a Rule Base (RB), constituted by the collection of fuzzy rules.
Although it is well known that knowledge is not sufficient in itself to increase the use of contraceptives methods [29], [30], [31] and in our study the "real contraceptive knowledge" has not been associated with the "use of safe method in the last relation" (results not shown), the relationship between real knowledge and IA is coherent.
Although certain facts about individual experiments are well known, complete knowledge of ground truth is not available for any biological microarray experiment.
While it is well known that knowledge alone did not always predict behaviour change or glycaemic control [ 25], health behaviour theories would generally include basic knowledge as a necessary element of health behaviour change and outcomes [ 26].
While horizontal gene transfer (HGT) in prokaryotes has been extensively studied and its significance in prokaryotic evolution is well known, our knowledge about HGT in eukaryotes is relatively limited [ 1– 4].
However, there are well known bottlenecks in knowledge acquisition and knowledge exploitation in a conventional knowledge-based system, especially if the knowledge is encoded in terms of production rules.
It is well known that medical knowledge is growing so rapidly that it is difficult or impossible for healthcare professionals to keep up.
Although materials selection to be applied for steam applications is well known, lack of knowledge is detected in the field of high temperature hydroxides corrosion.
