Ambiguity and the Representation Problem
I canvass eight possible approaches to representing ambiguity within truth-conditional semantics, and I argue that all are unsatisfactory. For example, it would be a mistake to hold that "x is a bank" is true iff x is a financial institution while "x is a bank" is true iff x is a slope, for then x would be a financial institution iff x is a slope. It would also be a mistake to hold that some to...
متن کاملAmbiguity, Children, Representation, and Sexuality
In her article "Ambiguity, Children, Representation, and Sexuality" Catharine Lumby considers current and historical scholarly and popular debates about the representation of children, including concerns about their sexualisation in such representations. The article begins by examining images taken by photographers in the Victorian era, including Charles Dodgson and Julia Cameron, and asks not ...
متن کاملLearning Word Representation Considering Proximity and Ambiguity
Distributed representations of words (aka word embedding) have proven helpful in solving natural language processing (NLP) tasks. Training distributed representations of words with neural networks has lately been a major focus of researchers in the field. Recent work on word embedding, the Continuous Bag-of-Words (CBOW) model and the Continuous Skip-gram (Skip-gram) model, have produced particu...
متن کاملAmbiguity and Multiplicity in Music Representation
Two evident problems in representing music are ambiguity and multiplicity. It is clear that the ‘same’ music can be represented in different ways. Some differences are simply because different facets of the music are represented: a score represents different things from an audio recording. Here I am concerned about differences which have at their root actual differences either in the detail of ...
متن کاملOrdering ambiguity revisited via position dependent mass pseudo-momentum operators
Ordering ambiguity associated with the von Roos position dependent mass (PDM) Hamiltonian is considered. A PDM-pseudo-momentum operator Π̂1 = −i [μ (x)∂x + g (x)] is introduced (the Hermiticity of which is secured by the condition g (x) = ∂xμ (x) /2) and generalized to ddimensions. Intertwining our Hamiltonian, HMM = Π̂ 2 d + V (x), with the von Roos d-dimensional PDM-Hamiltonian, HvR = T̂d (α, β,...
