Cristina Mota, Paula Carvalho, Anabela Marques Barreiro · 2016
This paper introduces Port4NooJ v3.0, the latest version of the Portuguese module for NooJ, highlights its main features, and details its three main new components: (i) a lexicon-grammar based dictionary of 5,177 human intransitive adjectives, and a set of local grammars that use the distributional properties of those adjectives for paraphrasing (ii) a polarity dictionary with 9,031 entries for sentiment analysis, and (iii) a set of priority dictionaries and local grammars for named entity recognition.These new components were derived and/or adapted from publicly available resources.The Port4NooJ v3.0 resource is innovative in terms of the specificity of the linguistic knowledge it incorporates.The dictionary is bilingual Portuguese-English, and the semantico-syntactic information assigned to each entry validates the linguistic relation between the terms in both languages.These characteristics, which cannot be found in any other public resource for Portuguese, make it a valuable resource for translation and paraphrasing.The paper presents the current statistics and describes the different complementary and synergic components and integration efforts.
