Factoring Predicate Argument and Scope Semantics : underspecified Semantics with LTAG [PDF]

open access: yes, 2003
In this paper we propose a compositional semantics for lexicalized tree-adjoining grammar (LTAG). Tree-local multicomponent derivations allow separation of the semantic contribution of a lexical item into one component contributing to the predicate ...

Hierarchy-aware Label Semantics Matching Network for Hierarchical Text Classification

open access: yesAnnual Meeting of the Association for Computational Linguistics, 2021
Hierarchical text classification is an important yet challenging task due to the complex structure of the label hierarchy. Existing methods ignore the semantic relationship between text and labels, so they cannot make full use of the hierarchical ...

Modulation Mining—Computer-Aided Exploration of Functional Chord Forms

open access: yesMusic & Science, 2023
The different labelling systems defined by the functional theories of harmony have been developed from about 1870 to 1950, without the help of computers. The complexity of harmonic labels spans from pure triads over added characteristic dissonances, over

Emojis as Pictures

open access: yesErgo, An Open Access Journal of Philosophy, 2023
I argue that emojis are essentially little pictures, rather than words, gestures, expressives, or diagrams. 🎁 means that the world looks like that, from some viewpoint.

Polyteam semantics [PDF]

open access: yesJournal of Logic and Computation, 2017
Abstract Team semantics is the mathematical framework of modern logics of dependence and independence in which formulae are interpreted by sets of assignments (teams) instead of single assignments as in first-order logic. In order to deepen the fruitful interplay between team semantics and database dependency theory, we define Polyteam ...

Action semantics in retrospect [PDF]

open access: yes, 2009
This paper is a themed account of the action semantics project, which Peter Mosses has led since the 1980s. It explains his motivations for developing action semantics, the inspirations behind its design, and the foundations of action semantics based on ...

Long-COVID Inducement Mechanism Based on the Path Module Correlation Coefficient

open access: yesMathematics, 2023
As the number of COVID-19 cases increases, the long-COVID symptoms become the focus of clinical attention. Based on the statistical analysis of long-COVID symptoms in European and Chinese populations, this study proposes the path module correlation ...

Semantic Segmentation by Semantic Proportions

open access: yesCoRR, 2023
Semantic segmentation is a critical task in computer vision aiming to identify and classify individual pixels in an image, with numerous applications in for example autonomous driving and medical image analysis. However, semantic segmentation can be highly challenging particularly due to the need for large amounts of annotated data.

Functional Big-step Semantics [PDF]

open access: yes, 2016
When doing an interactive proof about a piece of software, it is important that the underlying programming language’s semantics does not make the proof unnecessarily difficult or unwieldy.
