Towards Tractable and Practical ABox Abduction over Inconsistent Description Logic Ontologies

2015 · Proceedings of the AAAI Conference on Artificial Intelligence

ABox abduction plays an important role in reasoning over description logic (DL) ontologies. However, it does not work with inconsistent DL ontologies. To tackle this problem while achieving tractability, we generalize ABox abduction from the …

Function-words Adaptively Enhanced Attention Networks for Few-Shot Inverse Relation Classification

2022

The relation classification is to identify semantic relations between two entities in a given text. While existing models perform well for classifying inverse relations with large datasets, their performance is significantly reduced for few-shot learning. …

Approximating model-based a box revision in DL-lite: theory and practice

2015

Model-based approaches provide a semantically well justified way to revise ontologies. However, in general, model-based revision operators are limited due to lack of efficient algorithms and inexpressibility of the revision results. In this paper, we …
