    Cajal Mariñosa, Sergio; Rodríguez Hontoria, Horacio (2014-09)
    Article
    Open Access
    Terminology Extraction is an important Natural Language Processing task with multiple applications in many areas. The task has been approached from different points of view using different techniques. Language and domain ...
  • ParTes. Test suite for parsing evaluation 

    Lloberes Salvatella, Marina; Castellón Masalles, Irene; Padró, Lluís; González Pellicer, Edgar (2014-09-01)
    Article
    Open Access
    This paper presents ParTes, the first test suite in Spanish and Catalan for parsing qualitative evaluation. This resource is a hierarchical test suite of the representative syntactic structure and argument order phenomena. ...
  • A hybrid machine translation architecture guided by syntax 

    Labaka, Gorka; España Bonet, Cristina; Màrquez Villodre, Lluís; Sarasola, Kepa (2014-09-16)
    Article
    Restricted access - publisher's policy
    This article presents a hybrid architecture which combines rule-based machine translation (RBMT) with phrase-based statistical machine translation (SMT). The hybrid translation system is guided by the rule-based engine. ...
  • Automatic Selection of HPSG-Parsed Sentences for Treebank Construction 

    Marimon, Montserrat; Bel, Nuria; Padró, Lluís (2014-09-01)
    Article
    Open Access
    This article presents an ensemble parse approach to detecting and selecting high-quality linguistic analyses output by a hand-crafted HPSG grammar of Spanish implemented in the LKB system. The approach uses full agreement ...
  • Document-level machine translation as a re-translation process 

    Martínez Garcia, Eva; España Bonet, Cristina; Màrquez Villodre, Lluís (2014-09-22)
    Article
    Open Access
    Most of the current Machine Translation systems are designed to translate a document sentence by sentence ignoring discourse information and producing incoherencies in the final translations. In this paper we present some ...
  • Spectral learning of weighted automata: a forward-backward perspective 

    Balle Pigem, Borja de; Carreras Pérez, Xavier; Luque, Franco M.; Quattoni, Ariadna Julieta (2013-10-07)
    Article
    Restricted access - publisher's policy
    In recent years we have seen the development of efficient provably correct algorithms for learning Weighted Finite Automata (WFA). Most of these algorithms avoid the known hardness results by defining parameters beyond the ...
  • A Constraint-Based Hypergraph Partitioning Approach to Coreference Resolution 

    Sapena Masip, Emilio; Padró, Lluís; Turmo Borras, Jorge (2013-12)
    Article
    Open Access
    This work is focused on research in machine learning for coreference resolution. Coreference resolution is a natural language processing task that consists of determining the expressions in a discourse that refer to the ...
  • Plagiarism meets paraphrasing: insights for the next generation in automatic plagiarism detection 

    Barrón Cedeño, Luis Alberto; Vila, Marta; Martí, Maria Antonia; Rosso, Paolo (2013)
    Article
    Open Access
    Although paraphrasing is the linguistic mechanism underlying many plagiarism cases, little attention has been paid to its analysis in the framework of automatic plagiarism detection. Therefore, state-of-the-art plagiarism ...
  • Methods for cross-language plagiarism detection 

    Barrón Cedeño, Luis Alberto; Gupta, P.; Rosso, Paolo (2013-09)
    Article
    Restricted access - publisher's policy
    Three reasons make plagiarism across languages to be on the rise: (i) speakers of under-resourced languages often consult documentation in a foreign language, (ii) people immersed in a foreign country can still consult ...
  • Joint arc-factored parsing of syntactic and semantic dependencies 

    Lluis Martorell, Xavier; Carreras Pérez, Xavier; Màrquez Villodre, Lluís (2013-05)
    Article
    Restricted access - publisher's policy
    In this paper we introduce a joint arc-factored model for syntactic and semantic dependency parsing. The semantic role labeler predicts the full syntactic paths that connect predicates with their arguments. This process ...
