AbstractThis work presents a coreference resolution system of person entities based on a multi-pass architecture which sequentially applies a set of independent modules, using an entity-centric approach. Several evaluations show that the system obtains promising results in different scenarios (≈ 71% and ≈ 81% F1 CoNLL). Furthermore, the impact of coreference resolution in information extraction was analyzed, by applying an open information extraction system after the coreference resolution tool. The results of this test indicate that information extraction gives better both recall and precision results. The evaluations were carried out in Spanish, Portuguese and Galician, and all the resources and tools are freely distributed.
