The weekend effect is the tendency for Monday stock returns to be negative. The paper reports a posterior odds evaluation of the day-of-the-week and weekend effect that largely reverses earlier findings. The interaction of large sample sizes and fixed significance level hypothesis testing is identified as the likely source of disagreements between p-values and posterior probabilities. Analysis ...

Conceptual representations in language processing employ both linguistic distributional and embodied information. Here, we aim to demonstrate the roles of these two components in metaphor processing. The linguistic component is captured by linguistic distributional frequency (LDF), that is, how often the constituent words appear together in context. The embodied component, on the other hand, re...

We present the components of a processing chain for the creation, visualization, and validation of lexical resources (formed of terms and relations between terms). The core of the chain is a component for building lexical networks relying on Harris’ distributional hypothesis applied on the syntactic dependencies produced by the French parser FRMG on large corpora. Another important aspect conce...

In this paper, we explore the problem of identifying substitute relationship between food pairs from real-world food consumption data as the first step towards the healthier food recommendation. Our method is inspired by the distributional hypothesis in linguistics. Specifically, we assume that foods that are consumed in similar contexts are more likely to be similar dietarily. For example, a t...

Over the last two decades, numerous algorithms have been developed that successfully capture something of the semantics of single words by looking at their distribution in text and comparing these distributions in a vector space model. However, it is not straightforward to construct meaning representations beyond the level of individual words – i.e. the combination of words into larger units – ...

Formal semantics has traditionally distinguished between extensional and intensional aspects of meaning, roughly equivalent to reference and what people intuitively call "meaning", respectively. It has primarily focused on extension, since this allows for predictions to be made and tested by building models of meaning that are directly grounded on reference, using set theoretic tools. Distribut...

Some words are more contentful than others: for instance, make is intuitively more general than produce and fifteen is more ‘precise’ than a group. In this paper, we propose to measure the ‘semantic content’ of lexical items, as modelled by distributional representations. We investigate the hypothesis that semantic content can be computed using the KullbackLeibler (KL) divergence, an informatio...

Since their inception, distributional models of semantics have been criticized as inadequate cognitive theories of human semantic learning and representation. A principal challenge is that the representations derived by distributional models are purely symbolic and are not grounded in perception and action; this challenge has led many to favor feature-based models of semantic representation. We...

The goal of this study was to determine the effects of the L-type calcium channel blockers verapamil and diltiazem on the currents of voltage-gated potassium channel (fKv1.4ΔN), an N-terminal-deleted mutant of the ferret Kv1.4 potassium channel. Measurements were made using a two electrode voltage clamp technique with channels expressed stably in Xenopus oocytes. The fKv1.4ΔN currents displayed...
