dc.description.abstract | In this paper we investigate the way of combining different
taggers to improve their performance in the named entity recognition
task. The main resources used in our experiments are the publicly available
taggers TnT and TBL and a corpus of Spanish texts in which named
entities occurrences are tagged with BIO tags. We have defined three
transformations that provide us three additional versions of the training
corpus. The transformations change either the words or the tags, and
the three of them improve the results of TnT and TBL when they are
trained with the original version of the corpus. With the four versions of
the corpus and the two taggers, we have eight different models that can
be combined with several techniques. The experiments carried out show
that using machine learning techniques to combine them the performance
improves considerably. We improve the baselines for TnT (Fβ=1 value of
85.25) and TBL (Fβ=1 value of 87.45) up to a value of 90.90 in the best
of our experiments. | es |
