متن کاملSpecialization of Recursive Predicates from Positive Examples Only
Problem statement: Given an overly general (definite) program P and its intended semantics φ (the programmer’s intentions) where P does not satisfy φ, find out a new version P’ of P such that P’ satisfies φ. Approach: We proposed an approach for correcting overly general programs from positive examples by exploiting program synthesis techniques. The synthesized program, P’, is a specialization ...

The goal of the present study was to investigate event-related potential (ERP) responses to Dutch negative and positive polarity adverbs of degree presented in licensed and unlicensed contexts with negative and affirmative particles directly preceding the polarity item. To control for effects of the processing of negation as such, neutral adverbs were also presented in negative and affirmative ...
متن کاملPositive and negative polarity contrast sensitivity measuring app
Contrast sensitivity (CS) quantifies an observer's ability to detect the smallest (threshold) luminance difference between a target and its surrounding. In clinical settings, printed letter contrast charts are commonly used, and the contrast of the letter stimuli is specified by the Weber contrast definition. Those paper-printed charts use negative polarity contrast (NP, dark letters on bright ...
متن کاملNegative and Positive Polarity Items: Variation, Licensing, and Compositionality
In this chapter, we discuss the distribution and lexical properties of common varieties of negative polarity items (NPIs) and positive polarity items (PPIs). We establish first that NPIs can be licensed in negative, downward entailing, and nonveridical environments. Then we examine if the scalarity approach (originating in Kadmon and Landman 1993) can handle the attested NPI distribution and em...
