Task-Oriented Evaluation of Dependency Parsing with Open Information Extraction

Pablo Gamallo, Marcos García

Abstract: This paper presents a comparative evaluation of several Portuguese parsers. Our objective is to use dependency parsers in a specific information extraction task, namely Open Information Extraction (OIE), and measure the impact of each parser in this task. The experiments show that the scores obtained by the evaluated parsers are quite similar even though they allow to extract different (and then complementary) itens of information.
