Opinion Lexicons are linguistic resources annotated with semantic orientation of terms (positive and negative) and are important for opinion mining tasks. In the literature we see a variety of proposals for the construction of opinion lexicons using different linguistic resources and techniques. In this work, we propose and evaluate the integration of such(More)
FrameNet frames have been used to develop lexical databases and annotated corpora for different languages. This paper analyses the use of FrameNet frames to build a legal ontology for the Brazilian Law. In order to discuss the problems of such approach to ontology development, the lexical units evoking the Criminal_process frame were contrasted in English(More)
Universidade do Vale do Rio dos Sinos The noun compounds are productive constructions in a variety of languages, but the study of this linguistic phenomenon is still a challenge, since these constructions are idiosyncratic. In this paper, we present a study of the semantics of noun compounds in English. We selected compounds formed by two nouns, noun-noun(More)
Resumo. O objetivo deste trabalho é apresentar uma proposta de representação de relações de polissemia para as wordnets, particularmente, para a WordNet.Br. Abstract. This research aims at representing noun polysemy so that it can be useful to wordnet bases, particularly in WordNet.Br. A Semântica Lexical Cognitiva (SLC) mostrou ser a teoria mais adequada(More)
The need for the representation of both semantics and common sense and its organization in a lexical database or knowledge base has motivated the development of large projects, such as Wordnets, CYC and Mikrokosmos. Besides the generic bases, another approach is the construction of ontologies for specific domains. Among the advantages of such approach there(More)
This paper presents a preliminary study on the semantic description of the verbs of the Brazilian legal field. This is a study of the verbal semantics in order to construct a legal ontology of events. This work includes an exemplification of the analysis to be performed for the construction of ontology, presenting a ontology formalization proposal.
In this paper we present a novel methodology for automatic information extraction from natural language texts, based on the integration of linguistic rules, multiple ontologies and inference resources, integrated with an abstraction layer for linguistic annotation and data representation. The methodology allows ontology population with instances of events.(More)
This article aims to develop the subframe SENTENCING, which is part of the complex frame Knowledge Process frame in the Civil Procedural Law. Having the parent frame and its frame elements previously structured, we here elaborate the sentence subframe according to Frame Semantics and based on the FrameNet feature. To it so, we present the theory, the legal(More)
