Negation Without Negation in Probabilistic Logic Programming
Probabilistic logic programs without negation can have cycles (with a preference for false), but cannot represent all conditional distributions. Probabilistic logic programs with negation can represent arbitrary conditional probabilities, but with cycles they create logical inconsistencies. We show how allowing negative noise probabilities allows us to represent arbitrary conditional probabilit...
متن کاملNegation and Double-Negation of Chinese Oppositeness
Oppositeness refers to the paradigmatic relationship of two words holding the contrast meanings. The fact that linguistic opposite differs from logical contrast has been discussed in theories, but has not been tested in practice. In this paper, we investigate three main subtypes of Chinese oppositeness, via using logical tests of negation and double-negation. Result shows that purely logical te...
متن کاملNegation in Nonliteral Sentences
We investigate how people process negation in semantically distorted and metaphoric sentences. We present three experiments in which participants judged the truth of affirmative and negative sentences that were either literal or contained semantic illusions (Erickson & Mattson, 1981) or metaphors. In all experiments, negation increases processing times; although for semantic illusions, negation...
متن کاملNegation in Relevant
Negation raises three thorny problems for anyone seeking to interpret relevant logics. The frame semantics for negation in relevant logics involves a `point shift' operator. Problem number one is the interpretation of this operator. Relevant logics commonly interpreted take the inference from A and A _ B to B to be invalid, because the corresponding relevant conditional A ^ (A _ B) ! B is not a...
متن کاملNegation in SPARQL
This paper presents a thorough study of negation in SPARQL. The types of negation supported in SPARQL are identified and their main features discussed. Then, we study the expressive power of the corresponding negation operators. At this point, we identify a core SPARQL algebra which could be used instead of the W3C SPARQL algebra. Finally, we analyze the negation operators in terms of their com...
