Bayesian Belief Networks (BBNs) are a pow­ erful formalism for reasoning under uncer­ tainty but bear some severe limitations: they require a large amount of information be­ fore any reasoning process can start, they have limited contradiction handling capabil­ ities, and their ability to provide explana­ tions for their conclusion is still controversial. There exists a class of reasoning syste...

If there exists i ∈ Ys which is not among the s-top ranked ones, then we could replace class i in position ji within Ys with class k / ∈ Ys such that pk,t > pi,t obtaining a smaller loss. Next, we show that the optimal ordering within Y ∗ s,t is precisely ruled by the nonicreasing order of pi,t. By the sake of contradiction, assume there are i and k in Y ∗ s,t such that i preceeds k in Y ∗ s,t ...

There is widespread acknowledgement that the law of non-contradiction is an important logical principle. However, there is less-than-universal agreement on exactly what the law amounts to. This unclarity is brought to light by the emergence of paraconsistent logics in which contradictions are tolerated: From the point of view of proofs, not everything need follow from a contradiction — from the...

This article discusses the role that psychological culture of class teacher plays in the establishment and maintenance of psychological safety in a modern schoolchild. The problem of protection against psychological abuse within the educational environment of a school is particularly important in the current socio-cultural realm. The article analyzes many pedagogical and psychological studies r...

Minimum contradiction matrices are a useful complement to distance-based phylogenies. A minimum contradiction matrix represents phylogenetic information under the form of an ordered distance matrix Y(i) (,) (j) (n). A matrix element corresponds to the distance from a reference vertex n to the path (i, j). For an X-tree or a split network, the minimum contradiction matrix is a Robinson matrix. I...

This paper presents an analysis of contradictions in urban low carbon transitions as engines of change. Following Kojève’s reading of contradiction in Hegel’s oeuvre, I argue that contradiction is a constitutive feature of low carbon interventions. This is an alternative to conventional readings of contradiction as a provisional encounter of opposites in which one will eventually cancel out the...

Analysis of opinions (reviews) generated by users becomes increasingly exploited by a variety of applications. It allows to follow the evolution of the opinions or to carry out investigations on products. The detection of contradictory opinions about a Web resource (e.g., courses, movies, products, etc.) is an important task to evaluate the latter. In this paper, we focus on the problem of dete...
