What is this page?
This page lists the scientific contributions of an author, who either does not have a ResearchGate profile, or has not yet added these contributions to their profile.
It was automatically created by ResearchGate to create a record of this author's body of work. We create such pages to advance our goal of creating and maintaining the most comprehensive scientific repository possible. In doing so, we process publicly available (personal) data relating to the author as a member of the scientific community.
If you're a ResearchGate member, you can follow this page to keep up with this author's work.
If you are this author, and you don't want us to display this page anymore, please let us know.

This paper presents the technical details of Tiriba, which is a small autonomous electrical airplane used into pre-defined missions and applications such as agricultural and environmental monitoring. This class of aircrafts has taken advantage of the miniaturization of electronic components and modules such as GPS receivers, digital cameras, wirele...
In spite of its potential for bidirectionality, Extensible Dependency Grammar (XDG) has so far been used almost exclusively for parsing. This paper represents one of the first steps towards an XDG-based inte-grated generation architecture by tackling what is arguably the most basic among generation tasks: lexicalization. Herein we present a constra...
This paper focuses on how multiparadigm – namely, constraint, object-oriented and higher-order – programming can be drawn
upon not only to specify multiparameterized linguistic realization engines but also and above all to rationalize their configuration
into full-fledged generation modules for specific language-application pairs. We describe Manat...
This paper presents an automatic critiquer of Computer Science Abstracts in Portuguese, which formulates critiques and/or
suggestions of improvement based on automatic argumentative structure recognition. The recognition is performed by an statistical
classifier, similar to Teufel and Moens’s Argumentative Zoning (AZ) [1], but ported to work on Por...
This article identifies and addresses the major linguistic/conceptual, as opposed to logistic, issues faced in the morphosyntactic
tagging of MAC-Morpho, a 1.1 million word Brazilian Portuguese corpus of newspaper articles that has been developed in the
Lacio-Web Project. Rather than simply presenting the annotated corpus and describing its tagset,...
In this paper we report on the first validation effort for Portuguese for Veins Theory's Conjecture 1 (C1), which constrains anaphora resolution given the rhetoric structure of texts and whose applicability to Automatic Summarization interests us. Our experiment is preliminary in that only definite noun phrases are considered. Thereby we were able...
Natural Language Generation (NLG) concerns assigning linguistic form to data in non-linguistic representation (Reiter & Dale, 2000); Linguistic Realization (LR), in turn, com-prises all strictly target language-dependent NLG tasks. This work looks into RL systems from the perspective of three fundamental requirements namely generality, instantiab...
The eXtensible Dependency Grammar (XDG) is a very promising CP-natural framework with which to tackle varied NLP problems and their combinatorial complexity. XDG draws heavily on its non-transformational character for efficiency, which opens the issue of N:M mapping e.g. between syntactic and semantic structures. We resume discussion on this issue...
This paper describes a prototype for an interlingua-based human-aided machine translation system from Brazilian Portuguese into a linearized script of Libras, the Brazilian Sign Language. It is the first module of an experimental system for cross-modal translation aiming at overcoming the digital divide that segregates the Brazilian deaf community....

... In Brazil, several research groups focus on automatic and semi-automatic translation from oral to sign languages [2], [6], [16], [42,43,44,45], [49], [51] among others. Through the review of literature together with tests, it was observed that these translators still disregard morphosyntactic aspects of Libras, which, in turn, may cause the generation of ungrammatical sentences. ...
... On the Amharic SYN dimension, these nodes are constrained to have incoming del arcs. For more on empty nodes in XDG, see Gasser (2010) and Pelizzoni and Nunes (2005). ...
... Compared to English, and even to other languages such as Chinese or German, resources in Portuguese are rather limited. Most existing resources are geared towards basic syntactic and semantic analysis, such as Mac-Morpho [1,13] for part-of-speech tagging, or PropBank [12] for Semantic role labeling. Amongst task-oriented resources and associated benchmarks we can cite ASSIN [14] for semantic similarity and textual entailment; SIMPLEX-PB [16,17] for lexical simplification; and IDPT for irony detection [9,10,26]. ...
... As it has been pointed out previously, UAV provide superior mobility in comparison with traditional vehicles, allowing them to implement a wide array of applications such as automatic forest fire detention mechanisms [24], warehouse transportation, or precision agriculture [25]. As a consequence, some parts of the research community have been focusing on softwarizing different applications and functionalities provided by UAVs in order to dynamically create and deploy networking services over aerial networks. ...
... SciPo's automatic category recognition is performed by a statistical classifier similar to Teufel and Moens's Argumentative Zoning (AZ) [10], but ported to work on Portuguese abstracts [4]. AZ is rhetorical-level analysis of scientific articles which assigns a category (or "zone") to textual segments (sentence or group of sentences). ...
