Adaptive semantic web based environment for web resources
2008
Tulevaisuuden kaikkialle ulottuvassa internetissä tietojärjestelmät kommunikoivat paitsi käyttäjien kanssa, myös toisten sovellusten ja instrumentoitujen laitteiden kanssa. Tämän dynaamisen ja heterogeenisen digitaalisen ympäristön hallinnoimiseksi ja hyödyntämiseksi käyttämiemme laitteiden tulisi olla nykyistä proaktiivisempia ja tiedon tulisi olla kuvattu nykyistä kontekstitietoisemmalla tavalla.Lisäksi tulevaisuuden verkon resurssit tulisi kyetä kuvaamaan semanttisesti, jotta eri resurssit voidaan löytää ja sovittaa yhteen automaattisesti. Tämä mahdollistaa myös päätelmien tekemisen järjestelmien tiedoista sekä monimutkaisen kokonaisuuden komponenttien käyttäytymisen ohjaamisen helpommin…
Rough Pragmatic Description Logic
2013
In this chapter, a rough description logic is built on the basis of a pragmatic standpoint of representation of knowledge. The pragmatic standpoint has influenced the acceptance of a broader definition of the semantic network than that appearing in the literature. The definition of the semantic network is a motivation of the introduced semantics of the language of the descriptive logic. First, the theoretical framework of representation of knowledge that was proposed in the papers [24,25] is adjusted to the description of data processing. The pragmatic system of knowledge representation is determined, as well as situations of semantic adequacy and semantic inadequacy for represented knowled…
The nature of quantities influences the representation of arithmetic problems: evidence from drawings and solving procedures in children and adults
2017
International audience; When solving arithmetic problems, semantic factors influence the representations built (Gamo, Sander & Richard, 2010). In order to specify such interpretative processes, we created structurally isomorphic word problems that could be solved with two distinct algorithms. We tested whether a distinction between cardinal and ordinal quantities would lead solvers, due to their daily-life knowledge, to build different representations, influencing their strategies as well as the nature of their drawings. We compared 5th grade children and adults in order to assess the validity of this hypothesis with participants of varying arithmetic proficiency. The results confirmed that…
Deep semantic lung segmentation for tracking potential pulmonary perfusion biomarkers in chronic obstructive pulmonary disease (COPD): The multi‐ethn…
2019
Background Chronic obstructive pulmonary disease (COPD) is associated with high morbidity and mortality. Identification of imaging biomarkers for phenotyping is necessary for future treatment and therapy monitoring. However, translation of visual analytic pipelines into clinics or their use in large-scale studies is significantly slowed by time-consuming postprocessing steps. Purpose To implement an automated tool chain for regional quantification of pulmonary microvascular blood flow in order to reduce analysis time and user variability. Study type Prospective. Population In all, 90 MRI scans of 63 patients, of which 31 had a COPD with a mean Global Initiative for Chronic Obstructive Lung …
Schlegel y los enemigos de la ironía romántica
2007
Raga Rosaleny, Vicente - Vicente.Raga@uv.es La ironía de Schlegel, máximo representante, junto con Solger, de la ironía en el romanticismo alemán supuso una reinterpretación de la figura del Sócrates irónico de Platón. Sin embargo, su propuesta de una ironía pragmática fue rechazada de manera violenta por Hegel y Kierkegaard, que releyeron a Sócrates y su ironía enfrentándola a la de Schlegel. Para estos la propuesta del autor romántico era un reto a la sociedad que acabaría destruyéndola, pero, desde nuestra perspectiva tal lectura semántica de la ironía schlegeliana no se sostiene y, más bien, la propuesta del escritor alemán puede entenderse como un modo de crítica constructiva de la com…

DYNAMIC SEMANTIC USER PROFILING FROM IMPLICIT WEB NAVIGATION DATA
2014
International audience; On the Web, pages are often dynamically generated and allow publishers to individually adapt contents to each viewer. Underlying systems must correctly understand the user's context - crucial especially in the case of online advertisement placement. The article at hand describes our proposition of a novel profiling system, adapted to the special needs of digital advertising. Based on Semantic Web Technologies, the MindMinings system relies on an ontology to enable thorough understanding of each user's context and needs. The underlying ontology structure also provides enhanced interoperability with semantically annotated knowledge resources, notably vocabularies from …
Pellet: A Practical OWL-DL Reasoner
2007
In this paper, we present a brief overview of Pellet: a complete OWL-DL reasoner with acceptable to very good performance, extensive middleware, and a number of unique features. Pellet is the first sound and complete OWL-DL reasoner with extensive support for reasoning with individuals (including nominal support and conjunctive query), user-defined datatypes, and debugging support for ontologies. It implements several extensions to OWL-DL including a combination formalism for OWL-DL ontologies, a non-monotonic operator, and preliminary support for OWL/Rule hybrid reasoning. Pellet is written in Java and is open source.
Jason Intentional Learning: An Operational Semantics
2013
This paper introduces an operational semantics for defining Intentional Learning on Jason, the well known Java-based implementation of AgentSpeak(L). This semantics enables Jason to define agents capable of learning the reasons for adopting intentions based on their own experience. In this work, the use of the term Intentional Learning is strictly circumscribed to the practical rationality theory where plans are predefined and the target of the learning processes is to learn the reasons to adopt them as intentions. Top-Down Induction of Logical Decision Trees (TILDE) has proved to be a suitable mechanism for supporting learning on Jason: the first-order representation of TILDE is adequate t…
SEMANTIC MANAGEMENT OF INTELLIGENT MULTI-AGENTS SYSTEMS IN A 3D ENVIRONMENT
2011
8 pages; International audience; This paper presents a new approach combining the 3D elements composing the environment of mobile agents with semantic descriptors from Building Information Models. Our proposal is based on the IFC standard, which is used in the field of Civil Engineering to build digital models of buildings during the design phase. The semantic of IFC objects composing the 3D environment is used to select and set up 3D objects and elements of simulation scenarios. The result of this process dynamically generates the input files for the JaSIM environment that performs the simulation. These files deserve the representation of the virtual environment in which the simulation is …
