  • Acquiring information extraction patterns from unannotated corpora 

    Catala Roig, Neus (Universitat Politècnica de Catalunya, 2003-07-14)
    Doctoral thesis
    Open Access
    Information Extraction (IE) can be defined as the task of automatically extracting preespecified kind of information from a text document. The extracted information is encoded in the required format and then can be used, ...
  • Construcción automática de diccionarios de patrones de extracción de información 

    Catala Roig, Neus; Castell Ariño, Núria (1998-06)
    External research report
    Open Access
    One of the most important issues when constructing an Information Extraction System is how to obtain the knowledge needed for identifying relevant information in a document. A manual approach not only is an expensive ...

  • Feature selection for support vector machines by alignment with ideal kernel 

    Catala Roig, Neus; Martín Muñoz, Mario (2007-12)
    External research report
    Open Access
    Feature selection has several potentially beneficial uses in machine learning. Some of them are to improve the performance of the learning method by removing noisy features, to reduce the feature set in data collection, ...

    The current wide access to data from different neuroimaging techniques has permitted to obtain data to explore the possibility of finding objective criteria that can be used for diagnostic purposes. In order to decide which ...
  • 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)
    Conference report
    Open Access
    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 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
    Open Access
    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 ...
