• A common solution for tokenization and part-of-speech tagging: one-pass Viterbi algorithm vs. Iterative approaches 

      Graña Gil, Jorge; Alonso, Miguel A.; Vilares Ferro, Manuel (Springer-Verlag, 2002)
      Current taggers assume that input texts are already tokenized, i.e. correctly segmented in \emph{tokens} or high level information units that identify each individual component of the texts. This working hypothesis is ...

      Graña Gil, Jorge; Barcala Rodríguez, Francisco Mario; Vilares Ferro, Manuel (Springer-Verlag, 2002)
      [Abstract] One of the most important prior tasks for robust part-of-speech tagging is the correct tokenization or segmentation of the texts. This task can involve processes which are much more complex than the simple ...
    • GALENA: tabular DCG parsing for natural languages 

      Vilares Ferro, Manuel; Alonso, Miguel A.; Graña Gil, Jorge; Cabrero, David (1998)
      [Abstract] We present a definite clause based parsing environment for natural languages, whose operational model is the dynamic interpretation of logical push-down automata. We attempt to briefly explain our design decisions ...
    • Instrumentation of Synchronous Reactive Models for Performance Engineering 

      Valderruten Vidal, Alberto; Vilares Ferro, Manuel; Graña Gil, Jorge (Springer-Verlag, 1995)
    • Integrating external dictionaries into Part-of-speech taggers 

      Graña Gil, Jorge; Chappelier, J. C.; Vilares Ferro, Manuel (2001)
      [Abstract] The highest performances in part-of-speech tagging have been obtained by using stochastic methods, such as hidden Markov models. The running parameters of a hidden Markov model for tagging can be estimated from ...

    • Parsing as resolution 

      Vilares Ferro, Manuel; Graña Gil, Jorge (1993)
      [Abstract] A general context-free parsing algoritm based on logical dynamic programming techniques is described. The analyzer takes a general class of context-free grammar as drivers, and any finite string as input. In an ...
