Genomic in situ hybridization (GISH), using genomic DNA probes from Thinopyrum elongatum (Host) D.R. Dewey (E genome, 2n = 14), Th. bessarabicum (Savul. & Rayss) A. Love (J genome, 2n = 14), Pseudoroegneria stipifolia (Czern. ex Nevski) Love (S genome, 2n = 14), and Agropyron cristatum (L.) Gaertner (P genome, 2n = 14), was used to characterize the genome(More)
Thirty five bands (alleles) from six enzyme systems and fifty seven random amplified polymorphic DNA (RAPD) fragments were selected to analyse the genetic diversity of 33 polyploid wheatgrasses (Triticeae) populations of species Thinopyrum junceiforme and Elytrigia pycnantha, and two hybrids, one pentaploid and one novel 9-ploid. Dice’s similarity(More)
Aligning ontology is the process that aims to make various sources of interoperable knowledge. This process is much needed in applications of the semantic web. The algorithms alignment design (mapping, matching) is a relatively new area of research. Manually, determining terms that are semantically close in different ontology is a laborious and error-prone(More)
During the last decade, an invasive wheatgrass species (Elytrigia pycnantha) has colonized the low salt marshes of the Mont Saint Michel Bay resulting in an accelerated change in the vegetation. This study was conducted using microgeographical genetic diversity in order to understand the genetic structure of this invasive and clonal species. Genetic(More)
Anaphora resolution attempts to determine the correct antecedent of an anaphor (the term pointing back). In what follows, we propose an algorithm for the resolution of anaphoric pronouns that relies on lexical and syntactic knowledge incorporated in a modular approach based on constraints and preferences. Our objective was to find the correct antecedent to(More)
