Discriminative Relational Topic Models [PDF]

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 2015
Many scientific and engineering fields involve analyzing network data. For document networks, relational topic models (RTMs) provide a probabilistic generative process to describe both the link structure and document contents, and they have shown promise on predicting network structures and discovering latent topic representations.

Relational model, definition and denomination

open access: yesCalidoscópio, 2012
In this paper, the authors have addresses the links between, on the one hand, the meaning of a term, as represented in its definition, with all of its constituents, and on the other, its denomination.

A relational object model [PDF]

open access: yes, 1990
The relational model and its extensions are often considered incompatible with object-orientation. However, on the one hand nested relations provide the complex object features demanded by object models. Particularly, powerful query languages exploit the complex data structure while keeping the advantages of the declarative, set-oriented paradigm.

Probabilistic Relational Model Benchmark Generation [PDF]

open access: yes, 2016
The validation of any database mining methodology goes through an evaluation process where benchmarks availability is essential. In this paper, we aim to randomly generate relational database benchmarks that allow to check probabilistic dependencies ...

Modeling and Accessing Smart Materials with Integrity Constraints in the Shapes Constraint Language and Ontologies—The SmaDi Way

open access: yesAdvanced Engineering Materials, EarlyView.
Integrity constraints enforce consistency and completeness on data. The article discusses a newly developed validator for checking integrity constraints in Shapes Constraint Language (SHACL) through reduction to SPARQL Protocol and RDF Query Language (SPARQL) queries. It can be used with systems for ontology‐based database access.

Body social models of disability: Examining enactive and ecological approaches

open access: yesFrontiers in Psychology, 2023
Autistic philosopher and neurodiversity proponent Robert Chapman (2021) argues that disability may be best understood by utilizing an ecological functional model where the focus is on the intersection and overlaps between relational contributions to ...

Ignorance in the Relational Model [PDF]

open access: yes, 2006
We hypothesize that an extension-with-conditioning of Dempster-Shafer theory is suitable for encoding uncertainty and ignorance in the Relational Model.

Graph Neural Networks with Generated Parameters for Relation Extraction

open access: yes, 2019
Recently, progress has been made towards improving relational reasoning in machine learning field. Among existing models, graph neural networks (GNNs) is one of the most effective approaches for multi-hop relational reasoning.

Relational union organising in a healthcare setting: a qualitative study [PDF]

open access: yes, 2013
This article explores the impact of a relational organising model within a local UNISON NHS branch. While initial outcomes were modest, we argue that relational approaches have the potential to increase branch engagement with organising activity and to ...
