    • Size of the whole versus number of parts in genomes 

      Hernández Fernández, Antonio; Baixeries i Juvillà, Jaume; Forns, Núria; Ferrer Cancho, Ramon (2011-08)
      Article
      Accés obert
      It is known that chromosome number tends to decrease as genome size increases in angiosperm plants. Here the relationship between number of parts (the chromosomes) and size of the whole (the genome) is studied for other ...
    • Testing the robustness of laws of polysemy and brevity versus frequency 

      Hernández Fernández, Antonio; Casas Fernández, Bernardino; Ferrer Cancho, Ramon; Baixeries i Juvillà, Jaume (Springer, 2016)
      Text en actes de congrés
      Accés obert
      The pioneering research of G.K. Zipf on the relationship between word frequency and other word features led to the formulation of various linguistic laws. Here we focus on a couple of them: the meaning-frequency law, i.e. ...
    • The challenges of statistical patterns of language: the case of Menzerath's law in genomes 

      Ferrer Cancho, Ramon; Forns Fradera, Núria; Hernández Fernández, Antonio; Bel Enguix, Gemma; Baixeries i Juvillà, Jaume (2013-01)
      Article
      Accés obert
      The importance of statistical patterns of language has been debated over decades. Although Zipf's law is perhaps the most popular case, recently, Menzerath's law has begun to be involved. Menzerath's law manifests in ...
    • The evolution of polysemy in child language 

      Casas Fernández, Bernardino; Catala Roig, Neus; Ferrer Cancho, Ramon; Baixeries i Juvillà, Jaume (World Scientific Publishing Company, 2014)
      Text en actes de congrés
      Accés obert
      It has been hypothesized that early stages of language have left traces of simpler forms of language, for instance, in child language (Bickerton, 1990; Jackendoff, 1999). Word learning biases in children (Saxton, 2010) ...
    • The evolution of the exponent of Zipf's law in language ontogeny 

      Baixeries i Juvillà, Jaume; Elvevag, Brita; Ferrer Cancho, Ramon (2013-03-13)
      Article
      Accés obert
      It is well-known that word frequencies arrange themselves according to Zipf's law. However, little is known about the dependency of the parameters of the law and the complexity of a communication system. Many models of the ...
    • The exponent of Zipf’s law in language ontogeny. 

      Baixeries i Juvillà, Jaume; Ferrer Cancho, Ramon (World Scientific Publishing, 2012)

    • The parameters of Menzerath-Altmann law in genomes 

      Baixeries i Juvillà, Jaume; Hernández Fernández, Antonio; Forns Fradera, Núria; Ferrer Cancho, Ramon (Taylor & Francis, 2013)
      Article
      Accés obert
      The relationship between the size of the whole and the size of the parts in language and music is known to follow the Menzerath-Altmann law at many levels of description (morphemes, words, sentences, …). Qualitatively, the ...
    • The polysemy of the words that children learn over time 

      Casas Fernández, Bernardino; Catala Roig, Neus; Ferrer Cancho, Ramon; Hernández Fernández, Antonio; Baixeries i Juvillà, Jaume (2018-12)
      Article
      Accés obert
      Here we study polysemy as a potential learning bias in vocabulary learning in children. We employ a massive set of transcriptions of conversations between children and adults in English, to analyze the evolution of mean ...
    • Unified characterization of symmetric dependencies with lattices 

      Baixeries i Juvillà, Jaume; Balcázar Navarro, José Luis (2006)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Symmetric dependencies, or MultiValued Dependencies-like, are those dependencies that follow the deduction rules of MultiValued Dependencies (MVD’s). These are MVD-clauses, Degenerate MultiValued Dependencies (DMVD’s), and ...
    • Using concept lattices to mine functional dependencies 

      Baixeries i Juvillà, Jaume (2003-05)
      Report de recerca
      Accés obert
      Concept Lattices have been proved to be a valuable tool to represent the knowlegde in a database. In this paper we show how functional dependencies in databases can be extracted using Concept Lattices, not preprocessing ...
    • When is Menzerath-Altmann law mathematically trivial? A new approach 

      Ferrer Cancho, Ramon; Hernández Fernández, Antonio; Baixeries i Juvillà, Jaume; Debowski, Lukasz; Macutek, Jan (2014-12-12)
      Article
      Accés obert
      Menzerath’s law, the tendency of Z (the mean size of the parts) to decrease as X (the number of parts) increases, is found in language, music and genomes. Recently, it has been argued that the presence of the law in genomes ...
    • Yet a Faster Algorithm for Building the Hasse Diagram of a Galois Lattice 

      Baixeries i Juvillà, Jaume (Springer Verlag, 2009)
      Text en actes de congrés
      Accés obert
      Formal concept analysis (FCA) is increasingly applied to data mining problems, essentially as a formal framework for mining reduced representations (bases) of target pattern families. Yet most of the FCA-based miners, ...
    • Zipf’s laws of meaning in Catalan 

      Catala Roig, Neus; Baixeries i Juvillà, Jaume; Ferrer Cancho, Ramon; Padró, Lluís; Hernández Fernández, Antonio (Public Library of Science (PLOS), 2021-12-16)
      Article
      Accés obert
      In his pioneering research, G. K. Zipf formulated a couple of statistical laws on the relationship between the frequency of a word with its number of meanings: the law of meaning distribution, relating the frequency of a ...
