Sapena Masip, Emilio; Padró, Lluís; Turmo Borras, Jorge (2013-12)
Article
Accés obertThis 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 ... -
A global relaxation labeling approach to coreference resolution
Sapena Masip, Emilio; Padró, Lluís; Turmo Borras, Jorge (2010)
Text en actes de congrés
Accés restringit per política de l'editorialThis paper presents a constraint-based graph partitioning approach to coreference resolution solved by relaxation labeling. The approach combines the strengths of groupwise classifiers and chain formation methods in ... -
A graph partitioning approach to coreference resolution
Sapena Masip, Emilio; Padró, Lluís; Turmo Borras, Jorge (2009-01)
Report de recerca
Accés obertThis report presents a graph partitioning approach given a set of constraints to resolve coreferences. Coreference resolution is the task of determining which referring expressions in a discourse refer to the same entity. ... -
A graph partitioning approach to entity disambiguation using uncertain information
Sapena Masip, Emilio; Padró, Lluís; Turmo Borras, Jorge (Springer, 2008-08-31)
Text en actes de congrés
Accés restringit per política de l'editorialThis paper presents a method for Entity Disambiguation in Information Extraction from different sources in the web. Once entities and relations between them are extracted, it is needed to determine which ones are referring ... -
A question-driven information system adaptable via information extraction techniques
Sapena Masip, Emilio; González Pérez, Manuel; Padró, Lluís; Turmo Borras, Jorge (2008-06)
Report de recerca
Accés obertThis paper presents a system is composed by two main parts: The Information Extraction Process, which crawls the web and extracts all relevant knowledge that is then stored in the database, and the Question Processor which ... -

Alias assignment in information extraction
Sapena Masip, Emilio; Padró, Lluís; Turmo Borras, Jorge (-, 2007-01-31)
Text en actes de congrés
Accés restringit per política de l'editorialThis paper presents a general method for alias assignment task in information extraction. We compared two approaches to face the problem and learn a classifier. The first one quantifies a global similarity between the alias ... -
Coreference resolution survey
