This article describes a modular and multilingual NLP platform, which is enriched by a system of multicriteria decision-aid. Further we describe the linguistic data used by this platform as well as the applications based on its technology. MOTS-CLÉS : boîte à outils TALN, architecture modulaire et symbolique, analyse lexicale, syntaxique et sémantique, ontologies, multilinguisme, aide multicrit...

We address the problem of transferring semantic annotations, more specifically predicate labellings, from one language to another using parallel corpora. Previous work has transferred these annotations directly at the token level, leading to low recall. We present a global approach to annotation transfer that aggregates information across the whole parallel corpus. We show that this global meth...

We studied pure and 50/50 mixtures of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) and western hemlock (Tsuga heterophylla (Raf.) Sarg.) plantations to compare attained total yields between mixed-species stands as opposed to monocultures of equal densities. Whether overall stand density influences this outcome has not been adequately investigated, and to address this we included three den...

Hatchery-reared steelhead (Oncorhynchus mykiss) often have lower fitness than natural-origin fishwhen spawning in the wild. Fitness loss in hatcheries is partly due to genetic adaptation to captivity (domestication), but the underlying selection pressures driving adaptation remain unknown. Circumstantial evidence suggests that adaptation to hatcheries is accelerated when fish are reared at high...

In this paper, we propose word sense disambiguation methods based on lexical substitution and used for the task 1 of the SemDis2014 workshop. This methods are run by using short random walks on unipartite networks or bipartite networks. Some of these methods only use graphs automatically built from corpora (unsurpervised methods), others also use graphs built from handcraft resources filled by ...

We prove that random groups at density less than 1 6 act freely and cocompactly on CAT(0) cube complexes, and that random groups at density less than 1 5 have codimension-1 subgroups. In particular, Property (T ) fails to hold at density less than 1 5 . Abstract. Nous prouvons que les groupes aléatoires en densité strictement inférieure à 1 6 agissent librement et cocompactement sur un complexe...

Processes limiting recruitment of trees may have large impacts on forest dynamics. In this paper, we determined the effects of dispersal, shrubs (Rhododendron maximum), and density-dependent mortality on seed and seedling distributions of Southern Appalachian trees. We quantified the spatial distribution of seed rain, seed bank densities, first-year seedlings, and older than first-year seedling...

Brute-force word sense disambiguation (WSD) algorithms based on semantic relatedness are really time consuming. We study how to perform WSD faster and better on the span of a text. Several stochastic algorithms can be used to perform Global WSD. We focus here on an Ant Colony Algorithm and compare it to two other methods (Genetic and Simulated Annealing Algorithms) in order to evaluate them on ...
