“Spatial data mining, or knowledge discovery in spatial database, refers to the extraction of implicit knowledge, spatial relations, or other patterns not explicitly stored in spatial databases.” (Koperski and Han, 1995) Data mining, or knowledge discovery in databases, refers to the “ discovery of interesting, implicit, and previously unknown knowledge from large databases.” (Frawley et al, 1992)

Two experiments investigated the effect of prior knowledge on implicit and explicit learning. Implicit as opposed to explicit learning is sometimes characterized as unselective or purely statistical. During training, one group of participants was presented with category exemplars whose features could be tied together by integrative knowledge, whereas another group saw category exemplars with un...

Knowledge can be classified as explicit and implicit knowledge. This study investigates how national or regional culture influences on the explicit and implicit knowledge sharing behaviour in the context of multi-national virtual teams. The findings suggest national culture significantly influence on participants’ attitude to sharing knowledge in IT-enabled virtual teams. This study provides so...

We characterize the states of knowledge that are attainable in distributed systems, where communication is done by unreliable message exchange. The reason that certain states of knowledge are unattainable is a conservation principle which says that information about “nature” that can be obtained by combining all of the knowledge of the members of a closed system is preserved. We axiomatize the ...

In the present study, we used feature lists in a categorization task and required participants to report their subjective confidence to examine the dissociation between explicit and implicit knowledge. Whereas our findings replicated the effect of prior knowledge on learning, our results challenge the role of explicit and implicit knowledge suggested by previous research using a similar paradig...

We compare different epistemic notions in the presence of awareness of propositional variables: the logics of implicit knowledge (in which explicit knowledge is definable), explicit knowledge, and speculative knowledge. Different notions of bisimulation are suitable for these logics. We provide correspondence between bisimulation and modal equivalence on image-finite models for these logics. Th...
