Towards Cross-checking WordNet and SUMO Using Meronymy

no code implementations GWC 2018 Javier Álvez, German Rigau

We describe the practical application of a black-box testing methodology for the validation of the knowledge encoded in WordNet, SUMO and their mapping by using automated theorem provers.

This is not a Dataset: A Large Negation Benchmark to Challenge Large Language Models

1 code implementation24 Oct 2023 Iker García-Ferrero, Begoña Altuna, Javier Álvez, Itziar Gonzalez-Dios, German Rigau

We have used our dataset with the largest available open LLMs in a zero-shot approach to grasp their generalization and inference capability and we have also fine-tuned some of the models to assess whether the understanding of negation can be trained.

Commonsense Reasoning Using WordNet and SUMO: a Detailed Analysis

no code implementations GWC 2019 Javier Álvez, Itziar Gonzalez-Dios, German Rigau

Our final objective is the extraction of some guidelines towards a better exploitation of this commonsense knowledge framework by the improvement of the included resources.

Applying the Closed World Assumption to SUMO-based FOL Ontologies for Effective Commonsense Reasoning

no code implementations14 Aug 2018 Javier Álvez, Itziar Gonzalez-Dios, German Rigau

In this paper, we investigate the application of the Closed World Assumption (CWA) to enable a better exploitation of FOL ontologies by using state-of-the-art automated theorem provers.

Validating WordNet Meronymy Relations using Adimen-SUMO

no code implementations20 May 2018 Javier Álvez, Itziar Gonzalez-Dios, German Rigau

In this paper, we report on the practical application of a novel approach for validating the knowledge of WordNet using Adimen-SUMO.

Black-box Testing of First-Order Logic Ontologies Using WordNet

no code implementations29 May 2017 Javier Álvez, Paqui Lucio, German Rigau

Applying different quality criteria, our testing proposal enables a successful evaluation of a) the competency of several translations of SUMO into FOL and b) the performance of various automated ATPs.

Automatic White-Box Testing of First-Order Logic Ontologies

no code implementations29 May 2017 Javier Álvez, Montserrat Hermo, Paqui Lucio, German Rigau

Our proposal enables the detection of defects and serves to certify the grade of suitability --for reasoning purposes-- of every axiom.

Evaluating the Competency of a First-Order Ontology

no code implementations16 Oct 2015 Javier Álvez, Paqui Lucio, German Rigau

We report on the results of evaluating the competency of a first-order ontology for its use with automated theorem provers (ATPs).

Improving the Competency of First-Order Ontologies

no code implementations16 Oct 2015 Javier Álvez, Paqui Lucio, German Rigau

We introduce a new framework to evaluate and improve first-order (FO) ontologies using automated theorem provers (ATPs) on the basis of competency questions (CQs).
