Abstract Isotonic distributional regression (IDR) is a powerful non-parametric technique for the estimation of conditional distributions under order restrictions. In nutshell, IDR learns that are calibrated, and simultaneously optimal relative to comprehensive classes relevant loss functions, subject isotonicity constraints in terms partial on covariate space. Non-parametric isotonic quantile b...

In this work we investigate commonalities and differences between the semantic representations of concrete and abstract words using human judgments and distributional semantics. We tackle the following questions: a) Does distributional similarity imply similarity in concreteness vs. abstractness? b) How do concrete and abstract context words co-occur with concrete and abstract words? c) Are our...

This paper introduces the wordspace package, which turns Gnu R into an interactive laboratory for research in distributional semantics. The package includes highly efficient implementations of a carefully chosen set of key functions, allowing it to scale up to real-life data sets.

We sketch the basis of a categorical compositional distributional semantic approach to the analysis of verb phrase ellipsis.

Compositional distributional semantic models (CDSMs) have successfully been applied to the task of predicting the meaning of a range of linguistic constructions. Their performance on semicompositional word formation process of (morphological) derivation, however, has been extremely variable, with no large-scale empirical investigation to date. This paper fills that gap, performing an analysis o...

This paper describes the current status of research in Distributional Semantics looking at the results from the Montagovian tradition stand point. It considers the main aspects of the Montagovian view as binoculars to observe those results, in particular: compositionality, syntax-semantics interface, logical words and entailment. To this end, it reviews some work that aims to tackle those issue...

The pure common-value auction with private budget constraints that we study admits multiple equilibria, which replicate the bid distribution from the monotone, pure strategy equilibrium defined in Section 3. As explained in the main text, a bidder is indifferent among a range of bids. Thus, he has multiple best reply bids and may randomize among them. Provided that the resulting aggregate distr...

If either property rights or institutions are weak, agents who create wealth by cooperating will later have an incentive to fight over the distribution of it. In this paper we investigate theoretically and experimentally the circumstances under which welfare losses from investment in distributional contests destroy welfare gains from voluntary cooperation. We find that in situations, where the ...

Distributional semantics has been extended to phrases and sentences by means of composition operations. We look at how these operations affect similarity measurements, showing that similarity equations of an important class of composition methods can be decomposed into operations performed on the subparts of the input phrases. This establishes a strong link between these models and convolution ...
