Usage des organisateurs anti-entropique dans les documents électroniques : approche expérimentale des fenêtres ponctuelles

1999

International audience; Les documents électroniques permettent de nombreuses manières d'organiser, de présenter et d'accéder à l'information. Une utilisation pertinente de ces options par les auteurs requiert une bonne connaissance des effets que ces choix ont sur la représentation cognitive et les traitements faits par l'utilisateur. Cette approche des documents électroniques, sur la base du concept de représentation mentale, fournit un cadre d'analyse des structures et signaux propres à ce type d'écriture. Parmi ces signaux que nous appelons « organisateurs para-linguistiques » pour les distinguer de leurs équivalents purement textuels, un ensemble est destiné à réduire l'entropie due à l…

Evaluation de la pertinence dans un système de recommandation sémantique de nouvelles économiques

2014

Today in the commercial and financial sectors, staying informed about economic news is crucial and involves targeting good articles to read, because the huge amount of information. To address this problem, we propose an innovative article recommendation system, based on the integration of a semantic description of articles and on a knowledge ontological model. We support our recommendation system on an intrinsically efficient vector model that we have perfected to overcome the confusion existing in models between the concepts of similarity and relevancy that does not take into account the effects of the difference in the accuracy of the semantic descriptions precision between profiles and a…

Transcranial Magnetic Stimulation Trains at 1 Hz Frequency of the Right Posterior Parietal Cortex Facilitate Recognition Memory

2021

Neuroimaging, neuropsychological, and brain stimulation studies have led to contrasting findings regarding the potential roles of the lateral parietal lobe in episodic memory. Studies using brain stimulation methods reported in the literature do not offer unequivocal findings on the interactions with stimulation location (left vs. right hemisphere) or timing of the stimulation (encoding vs. retrieval). To address these issues, active and sham 1 Hz repetitive transcranial magnetic stimulation (rTMS) trains of 600 stimuli were applied over the right or left posterior parietal cortex (PPC) before the encoding or before the retrieval phase of a recognition memory task of unknown faces in a grou…

Reputation and financial reporting in Finnish public organizations

2021

PurposeThis article analyzes the links between financial reports and reputation in the context of Finnish public sector organizations. In general, the paper discusses the accounting treatment of intangible and tangible assets and the quality and relevance of public sector financial reporting.Design/methodology/approachFor data, we combine three data sets: financial statement information of eight anonymous Finnish public organizations, the results of a reputation survey among their key stakeholders (N = 914) and a sample of the social media sentiment around the organizations.FindingsOur findings suggest that a decrease in spending and, surprisingly in the nonprofit sector, an increase in the…

An Automatic Ontology-Based Approach to Support Logical Representation of Observable and Measurable Data for Healthy Lifestyle Management: Proof-of-C…

2020

Background Lifestyle diseases, because of adverse health behavior, are the foremost cause of death worldwide. An eCoach system may encourage individuals to lead a healthy lifestyle with early health risk prediction, personalized recommendation generation, and goal evaluation. Such an eCoach system needs to collect and transform distributed heterogenous health and wellness data into meaningful information to train an artificially intelligent health risk prediction model. However, it may produce a data compatibility dilemma. Our proposed eHealth ontology can increase interoperability between different heterogeneous networks, provide situation awareness, help in data integration, and discover…

On the use of multi-temporal series of COSMO-SkyMed data for LANDcover classification and surface parameter retrieval over agricultural sites

2011

The objective of this paper is to report on the activities carried out during the first year of the Italian project “Use of COSMO-SkyMed data for LANDcover classification and surface parameters retrieval over agricultural sites” (COSMOLAND), funded by the Italian Space Agency. The project intends to contribute to the COSMO-SkyMed mission objectives in the agriculture and hydrology application domains.

Cognitive Linguistics as the Underlying Framework for Semantic Annotation

2012

In recent years many attempts have been made to design suitable sets of rules aimed at extracting the semantic meaning from plain text, and to achieve annotation, but very few approaches make extensive use of grammars. Current systems are mainly focused on extracting the semantic role of the entities described in the text. This approach has limitations: in such applications the semantic role is conceived merely as the meaning of the involved entities without considering their context. As an example, current semantic annotators often specify a date entity without any annotation regarding the kind of the date itself i.e. a birth date, a book publication date, and so on. Moreover, these system…
