Learning Structure-Aware Representations of Dependent Types

1 code implementation3 Feb 2024 Konstantinos Kogkalidis, Orestis Melkonian, Jean-Philippe Bernardy

Agda is a dependently-typed programming language and a proof assistant, pivotal in proof formalization and programming language theory.

Algebraic Positional Encodings

1 code implementation26 Dec 2023 Konstantinos Kogkalidis, Jean-Philippe Bernardy, Vikas Garg

We introduce a novel positional encoding strategy for Transformer-style models, addressing the shortcomings of existing, often ad hoc, approaches.

SPINDLE: Spinning Raw Text into Lambda Terms with Graph Attention

1 code implementation23 Feb 2023 Konstantinos Kogkalidis, Michael Moortgat, Richard Moot

This paper describes SPINDLE - an open source Python module implementing an efficient and accurate parser for written Dutch that transforms raw text input to programs for meaning composition, expressed as {\lambda} terms.

Graph Attention

Geometry-Aware Supertagging with Heterogeneous Dynamic Convolutions

2 code implementations23 Mar 2022 Konstantinos Kogkalidis, Michael Moortgat

The syntactic categories of categorial grammar formalisms are structured units made of smaller, indivisible primitives, bound together by the underlying grammar's category formation rules.

Discontinuous Constituency and BERT: A Case Study of Dutch

1 code implementation Findings (ACL) 2022 Konstantinos Kogkalidis, Gijs Wijnholds

In this paper, we set out to quantify the syntactic capacity of BERT in the evaluation regime of non-context free patterns, as occurring in Dutch.

Probing Language Models

A Logic-Based Framework for Natural Language Inference in Dutch

1 code implementation7 Oct 2021 Lasha Abzianidze, Konstantinos Kogkalidis

Pairs of semantic terms are then fed to an automated theorem prover for natural logic which reasons with them while using the lexical relations found in the Open Dutch WordNet.

Improving BERT Pretraining with Syntactic Supervision

1 code implementation21 Apr 2021 Giorgos Tziafas, Konstantinos Kogkalidis, Gijs Wijnholds, Michael Moortgat

Bidirectional masked Transformers have become the core theme in the current NLP landscape.

Fighting the COVID-19 Infodemic with a Holistic BERT Ensemble

1 code implementation NAACL (NLP4IF) 2021 Giorgos Tziafas, Konstantinos Kogkalidis, Tommaso Caselli

This paper describes the TOKOFOU system, an ensemble model for misinformation detection tasks based on six different transformer-based pre-trained encoders, implemented in the context of the COVID-19 Infodemic Shared Task for English.

Misinformation

Neural Proof Nets

1 code implementation CONLL 2020 Konstantinos Kogkalidis, Michael Moortgat, Richard Moot

Linear logic and the linear {\lambda}-calculus have a long standing tradition in the study of natural language form and meaning.
