Presupposition relations between verbs are not very well covered in existing lexical semantic resources. We propose a weakly supervised algorithm for learning presupposition relations between verbs that distinguishes five semantic relations: presupposition, entailment, temporal inclusion, antonymy and other/no relation. We start with a number of seed verb pairs selected manually for each semant...

We present an example of a complete and minimal Gabor system consisting of time-frequency shifts of a Gaussian, localized at the coordinate axes in the time-frequency plane (phase space). Asymptotically, the number of time-frequency shifts contained in a disk centered at the origin is only 2/π times the number of points from the von Neumann lattice found in the same disk. Requiring a certain re...

New measurements of KL and KS decays from the NA48 experiment are presented. From data taken in the year 2001, the value of the Ke3 charge asymmetry has been determined to δL(e) = (3.317 ± 0.070stat ± 0.072syst) × 10−3. From a special high-intensity KS run period performed in 2000, NA48 has found a limit of 1.4 × 10−6 on the KS → 3π branching ratio and measured the parameter η000. The same data...

This paper proposes a more comprehensive look at the ideas of KS and Area Under the Curve AUC of a cumulative gains chart to develop a model quality statistic which can be used agnostically to evaluate the quality of a wide range of models in a standardized fashion. It can be either used holistically on the entire range of the model or at a given decision threshold of the model. Further it can ...

TagClouds is a popular visualization for the collaborative tags. However it has some instinct problems such as linguistic issues, high semantic density and poor understanding of hierarchical structure and semantic relation between tags. In this paper we investigate the ways to support semantic understanding of collaborative tags and propose an improved visualization named TagClusters. Based on ...

The way participants adapt their search to the specifics of different types of analogies is not fully understood. We compared the effects of two types of semantic distractors. The first were related to C by a semantic relation which had nothing to do with the semantic relation used in the A:B pairs, whereas the second, the so-called ”double distractors”, were not only related to C but also had ...

We prove that the boundary of the bounded Fatou components for polynomials are Jordan curves, except maybe for Siegel disks.
