Paper

In this work, we have analyzed the effects of negation on the semantic orientation in Basque. The analysis shows that negation markers can strengthen, weaken or have no effect on sentiment orientation of a word or a group of words. Using the Constraint Grammar formalism, we have designed and evaluated a set of linguistic rules to formalize these three phenomena. The results show that two phenomena, strengthening and no change, have been identified accurately and the third one, weakening, with acceptable results.

In this paper we present the ADAPT system built for the Basque to English Low Resource MT Evaluation Campaign. Basque is a low-resourced, morphologically-rich language. This poses a challenge for Neural Machine Translation models which usually achieve better performance when trained with large sets of data.

DIANN izeneko atazaren helburua biomedikuntzako ikerketako testuetan ezintasunak automatikoki detektatzean datza (adibidez, "ikusmenaren galera", "dementzia" etab.). Ezintasun hauek ezeztatuta egon daitezke ("dementziarik gabeko gaixoetan...") eta bai ezeztatutako baita ezeztatu gabeko ezintasunak, ingelesezko eta gaztelerazko Elsevier-eko 500 artikulu-laburpenetan detektatu behar dira. Ixa taldeak ataza honetan sistemarik hoberena aurkeztu du Ibereval 2018an.
