  • A commentary on “The now-or-never bottleneck: a fundamental constraint on language”, by Christiansen and Chater (2016) 

    Ferrer Cancho, Ramon (RAM-Verlag, 2017-07-02)
    Article
    Accés obert
    In a recent article, Christiansen and Chater (2016) present a fundamental constraint on language, i.e. a now-or-never bottleneck that arises from our fleeting memory, and explore its implications, e.g., chunk-and-pass ...
  • Compact union of disjoint boxes: An efficient decomposition model for binary volumes

    Article
    Accés obert
    This paper presents in detail the CompactUnion of Disjoint Boxes (CUDB), a decomposition modelfor binary volumes that has been recently but brieflyintroduced. This model is an improved version of aprevious model called ...
  • A formal context for acyclic join dependencies 

    Baixeries i Juvillà, Jaume (2017)
    Article
    Accés obert
    Acyclic Join Dependencies (AJD) play a crucial role in database design and normalization. In this paper, we use Formal Concept Analysis (FCA) to characterize a set of AJDs that hold in a given dataset. This present work ...
  • A methodology to discover and understand complex patterns: interpreted integrative multiview clustering (I2MC)

    The main goal of this work is to develop a methodology for finding nutritional patterns from a variety of individual characteristics which can contribute to better understand the interactions between nutrition and health, ...
  • The entropy of words-learnability and expressivity across more than 1000 languages 

    Bentz, Chris; Alikaniotis, Dimitrios; Cysouw, Michael; Ferrer Cancho, Ramon (2017-06-01)
    Article
    Accés obert
    The choice associated with words is a fundamental property of natural languages. It lies at the heart of quantitative linguistics, computational linguistics and language sciences more generally. Information theory gives ...

    This paper characterizes part of an interdisciplinary research effort on Artificial Intelligence (AI) techniques and tools applied to Environmental Decision-Support Systems (EDSS). WaWO+ the ontology we present here, ...
  • Random crossings in dependency trees 

    Ferrer Cancho, Ramon (2017-03-01)
    Article
    Accés obert
    It has been hypothesized that the rather small number of crossings in real syntactic dependency trees is a side-effect of pressure for dependency length minimization. Here we answer a related ...
  • MetaShot: an accurate workflow for taxon classification of host-associated microbiome from shotgun metagenomic data 

    Fosso, Bruno; Santamaria, Monica; D'Antonio, M.; Lovero, D.; Corrado, G.; Vizza, E.; Passaro, N.; Garbuglia, A.R.; Capobianchi, M.R.; Crescenzi, M.; Valiente Feruglio, Gabriel Alejandro; Pesole, Graziano (2017-06-01)
    Article
    Accés obert
    Shotgun metagenomics by high-throughput sequencing may allow deep and accurate characterization of host-associated total microbiomes, including bacteria, viruses, protists and fungi. However, the analysis of such sequencing ...
