    • Comparing non-parametric ensemble methods for document clustering 

      González Pellicer, Edgar; Turmo Borras, Jorge (Springer Verlag, 2008)
      Conference report
      Restricted access - publisher's policy
      The biases of individual algorithms for non-parametric document clustering can lead to non-optimal solutions. Ensemble clustering methods may overcome this limitation, but have not been applied to document collections. ...

    • Non-parametric document clustering by ensemble methods 

      González Pellicer, Edgar; Turmo Borras, Jorge (2008-03)
      Article
      Open Access
      Los sesgos de los algoritmos individuales para clustering no paramétrico de documentos pueden conducir a soluciones no óptimas. Los métodos de consenso podrían compensar esta limitación, pero no han sido probados sobre ...

    • 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. ...

    • TALP-UPC at TREC 2005: Experiments using voting scheme among three heterogeneous QA systems 

      Ferrés Domènech, Daniel; Kanaan Izquierdo, Samir; González Pellicer, Edgar; Ageno Pulido, Alicia; Fuentes Fort, Maria; Rodríguez Hontoria, Horacio; Surdeanu, Mihai; Turmo Borras, Jorge (2005)
      Conference report
      Open Access
      This paper describes the experiments of the TALP-UPC group for factoid and ’other’ (definitional) questions at TREC 2005 Main Question Answering (QA)task. Our current approach for factoid questions is based on a voting ...

    • The TALP participation at TAC-KBP 2012 

      González Pellicer, Edgar; Rodríguez Hontoria, Horacio; Turmo Borras, Jorge; Comas Umbert, Pere Ramon; Mehdizadeh Naderi, Ali; Ageno Pulido, Alicia; Sapena Masip, Emilio; Vila Rigat, Marta; Martí, Maria Antònia (2012)
      Conference report
      Open Access
      This document describes the work performed by the Universitat Politècnica de Catalunya (UPC) in its first participation at TAC-KBP 2012 in both the Entity Linking and the Slot Filling tasks.

    • Unsupervised document clustering by weighted combination 

      González Pellicer, Edgar; Turmo Borras, Jorge (2006-05)
      Research report
      Open Access
      This report proposes a novel unsupervised document clustering approach based on weighted combination of individual clusterings. Two non-weighted combination methods are adapted to work in a weighted fashion: a graph based ...

    • Unsupervised ensemble minority clustering 

      González Pellicer, Edgar; Turmo Borras, Jorge (2012-03)
      Research report
      Open Access
      Cluster a alysis lies at the core of most unsupervised learning tasks. However, the majority of clustering algorithms depend on the all-in assumption, in which all objects belong to some cluster, and perform poorly on ...

    • Unsupervised relation extraction by massive clustering 

      González Pellicer, Edgar; Turmo Borras, Jorge (2009)
      Conference report
      Open Access
      The goal of Information Extraction is to automatically generate structured pieces of information from the relevant information contained in text documents. Machine Learning techniques have been applied to reduce the cost ...
