WebTribe: Implicit Community Clustering by Semantic Analysis
2010
International audience; Since the advent of Web 2.0, any user becomes a content provider through personal websites, posts on wikis and forums, recommendations, annotations, etc. In this paper, we propose a method to analyze the interests of users based on their publishing activities, by positioning them into a semantic graph. We describe the WebTribe system that allows to extract topic information from collaborative websites and to query the resulting clusters of users.
Simulated eutrophication and browning alters zooplankton nutritional quality and determines juvenile fish growth and survival
2018
Source at https://doi.org/10.1002/ece3.3832. The first few months of life is the most vulnerable period for fish and their optimal hatching time with zooplankton prey is favored by natural selection. Traditionally, however, prey abundance (i.e., zooplankton density) has been considered important, whereas prey nutritional composition has been largely neglected in natural settings. High‐quality zooplankton, rich in both essential amino acids (EAAs) and fatty acids (FAs), are required as starting prey to initiate development and fast juvenile growth. Prey quality is dependent on environmental conditions, and, for example, eutrophication and browning are two major factors defining primary produ…
HOWERD: A Hidden Markov Model for Automatic OWL-ERD Alignment
2016
The HOWERD model for estimating the most likely alignment between an OWL ontology and an Entity Relation Diagram (ERD) is presented. Automatic alignment between relational schema and ontology represents a big challenge in Semantic Web research due to the different expressiveness of these representations. A relational schema is less expressive than the ontology; this is a non trivial problem when accessing data via an ontology and for ontology storing by means of a relational schema. Existent alignment methodologies fail in loosing some contents of the involved representations because the ontology captures more semantic information, and several elements are left unaligned. HOWERD relies on a…
Spatialization of the Semantic Web
2012
syntax for Horn-like rules. The SWRL as the form, antecedentconsequent, where both antecedent and consequent are conjunctions of atoms written a1^ ... ^ an. Atoms in rules can be of the form C(x), P(x,y), Q(x,z), sameAs(x,y), differentFrom(x,y), or builtIn(pred, z1, ..., zn), where C is an OWL description, P is an OWL individual-valued property, Q is an OWL data-valued property, pred is a datatype predicate URIref, x and y are either individual-valued variables or OWL individuals, and z, z1, ... zn are either data-valued variables or OWL data literals. An OWL data literal is either a typed literal or a plain literal. Variables are indicated by using the standard convention of prefixing the…
Working with Multiple Ontologies on the Semantic Web.
2016
The standardization of the second generation Web Ontology Language, OWL, leaves a crucial issue for Web-based ontologies unsatisfactorily resolved: how to represent and reason with multiple distinct, but linked, ontologies. OWL provides the owl:imports construct which, roughly, allows Web ontologies to include other Web ontologies, but only by merging all the linked ontologies into a single logical "space". Recent work on multidimensional logics, fusions and other combinations of modal logics, distributed and contextual logics, and the like have tried to find formalisms wherein knowledge bases (and their logic) are kept more distinct but yet affect each other. These formalisms have various …

A girl with inverted triplication of chromosome 3q25.3 → q29 and multiple congenital anomalies consistent with 3q duplication syndrome
2005
We report a newborn girl with intrachromosomal triplication of 3q25.3 --> q29 (mosaicism) who died at the age of 3.5 weeks due to her malformations. She demonstrated disproportionate short stature with short limbs, a prominent and hairy forehead, thick eyebrows, synophrys, small upturned nose, full cheeks, micrognathia, and low set malformed and posteriorly rotated ears, short and webbed neck, hydrocephalus, Dandy-Walker malformation, spina bifida, complex heart defect (ventricular and atrial septal defect, malrotation, and interrupted aortic arch), omphalocele, polycystic kidneys, postaxial polydactyly of left hand, and generalized hirsutism; all signs have been associated with the dup(3q)…
Journey to the Centre of Europe
1998
De nombreuses institutions locales utilisent, dans de véritables opérations de marketing territorial, une analogie entre centre géographique et centre géométrique du cercle pour valoriser leur localisation. Il s'agit là d'une conception particulière et étroite d'une idée plus riche et plus insaisissable. Le concept de centre est une construction économique et sociale mais il repose sur certains principes consensuels : l'accessibilité, la concentration,l'inégalité, la relativité spatiale et temporelle et la subjectivité compte tenu de sa dimension symbolique. Définir un centre c'est d'abord borner un sous espace de référence. Représenter le centre économique par le centre d'un cercle nécessi…
Jautājumu veidi uzņēmumu mājas lapās
2018
Uzņēmumiem mājaslapas ir nozīmīgs komunikācijas kanāls, kas klientiem ļauj uzzināt nepieciešamo informāciju visā mājaslapā vai ‘Biežāk uzdotie jautājumi’ un ‘Palīdzība’ sadaļās, kur atrodamas atbildes uz dažādiem jautājumiem. Pētījuma mērķis bija veikt jautājumu analīzi un salīdzināt to lietojumu mazumtirdzniecības un banku mājaslapās. Izpētes procesā tika pielietota diskursa analīze. Rezultāti norāda, ka banku mājaslapas satur vairāk jautājumu nekā mazumtirdzniecības mājaslapas, tomēr noteikta veida jautājumi – wh-/how jautājumi, plašais modālo palīgdarbības vārdu can un will, kā arī tagadnes laika lietojums jautājumu formēšanā bija līdzīgas valodu iezīmes abu sfēru mājaslapās. Var secināt…
