Relations in biomedical ontologies [PDF]

Genome Biology, 2005
AbstractTo enhance the treatment of relations in biomedical ontologies we advance a methodology for providing consistent and unambiguous formal definitions of the relational expressions used in such ontologies in a way designed to assist developers and users in avoiding errors in coding and annotation.

Interaction Relation Ontology Learning [PDF]

Journal of Computational Biology, 2014
Ontology is widely used in semantic computing and reasoning, and various biomedicine ontologies have become institutionalized to make the heterogeneous knowledge computationally amenable. Relation words, especially verbs, play an important role when describing the interaction between biological entities in molecular function, biological process, and ...

Ontologizing semantic relations [PDF]

Proceedings of the 21st International Conference on Computational Linguistics and the 44th annual meeting of the ACL - ACL '06, 2006
Many algorithms have been developed to harvest lexical semantic resources, however few have linked the mined knowledge into formal knowledge repositories. In this paper, we propose two algorithms for automatically ontologizing (attaching) semantic relations into WordNet.

Ontology-based data access with databases: a short course [PDF]

, 2013
Ontology-based data access (OBDA) is regarded as a key ingredient of the new generation of information systems. In the OBDA paradigm, an ontology defines a high-level global schema of (already existing) data sources and provides a vocabulary for user ...

Polynomial conjunctive query rewriting under unary inclusion dependencies [PDF]

, 2011
Ontology-based data access (OBDA) is widely accepted as an important ingredient of the new generation of information systems. In the OBDA paradigm, potentially incomplete relational data is enriched by means of ontologies, representing intensional ...

Heidegger’s Relational Ontology

Maynooth Philosophical Papers, 2022
The understanding of Being in terms of substance has given rise to many philosophical problems, the most obvious and persistent of which is subject/object dualism. Heidegger recognises the problems substance ontology has created and rejects the ontological primacy of the subject.

Ontology-Based Relational Product Recommendation System

Computational and Mathematical Methods in Medicine, 2022
As online shopping has expanded, product recommendations on e-commerce websites have gained significance. Systems for recommending products use information about site navigation and user leave-over to suggest more products. Customers who use a product recommendation system choose better and find items more quickly. On e-commerce websites, collaborative
