In this paper, we present a machine learning system for classifying subject ellipsis in Spanish as either referential or non-referential. To the best of our knowledge, this is the first attempt to automatically identify non-referential ellipsis in Spanish. An evaluation of our system against 6,827 finite verbs shows an accuracy of 87%.

The rst part of the paper develops a novel, sortally-based approach to the problem of aspectual composition. The account is argued to be superior on both empirical and computational grounds to previous semantic approaches relying on referential homogeneity tests. While the account is restricted to manner-of-motion verbs, it does cover their interaction with mass terms, amount phrases, locative ...

Tracking word-object co-occurrence statistics can reduce referential uncertainty during word learning. But human learners are constrained by limits on attention and memory, and therefore must store a subset of the information available—how do they select what information to store? We hypothesize that the presence of referential cues like eye gaze guides how learners allocate their attention. In...

Please cite this article in press as: Clay, Z., et Behaviour (2012), doi:10.1016/j.anbehav.201 Alarm calls and food-associated calls from a diverse range of species are said to be functionally referential, in that receivers can use these sounds to predict environmental events in the absence of other contextual cues. The evolutionary driver for referential alarm calls has been hypothesized to be...

One of the core components of language is referring, which requires the speaker to choose between expressions that are highly explicit (e.g., the UNC professor, or Peter), and reduced lexical forms (e.g., he). This paper reviews claims that this process is largely driven by the accessibility or salience of the referent, and the psychological processes that underlie these effects. Two classes of...

REFERENTIAL GROUNDING TOWARDS MEDIATING SHARED PERCEPTUAL BASIS IN SITUATED DIALOGUE

Language learners must learn the meanings of many thousands of words, despite those words occurring in complex environments in which infinitely many meanings might be inferred by the learner as a word's true meaning. This problem of infinite referential uncertainty is often attributed to Willard Van Orman Quine. We provide a mathematical formalisation of an ideal cross-situational learner attem...

This study used positron emission tomography (PET) to identify the brain substrate of self-referential reflective activity and to investigate its relationship with brain areas that are active during the resting state. Thirteen healthy volunteers performed reflective tasks pertaining to three different matters (the self, another person, and social issues) while they were scanned. Rest scans were...

Wójcicki has provided a characterization of selfextensional logics as those that can be endowed with a complete local referential semantics. His result was extended by Jansana and Palmigiano, who developed a duality between the category of reduced congruential atlases and that of reduced referential algebras over a fixed similarity type. This duality restricts to one between reduced atlas model...

When humans and artificial agents (e.g. robots) have mismatched perceptions of the shared environment, referential communication between them becomes difficult. To mediate perceptual differences, this paper presents a new approach using probabilistic labeling for referential grounding. This approach aims to integrate different types of evidence from the collaborative referential discourse into ...
