Answering Portuguese Questions [chapter]

Luís Fernando Costa, Luís Miguel Cabral
2008 Lecture Notes in Computer Science  
Esfinge is a general domain Portuguese question answering system that participated in the last four editions of CLEF.  ...  This system uses the Web as a fundamental resource in its architecture, using information redundancy rather than sophisticated annotations of the document collections to retrieve answers.  ...  This work was done in the scope of the Linguateca project, jointly funded by the Portuguese Government and the European Union (FEDER and FSE) under contract ref. POSC/339/1.3/C/NAC.  ...

Using Answer Retrieval Patterns to Answer Portuguese Questions [chapter]

Luís Fernando Costa
2009 Lecture Notes in Computer Science  
Esfinge is a general domain Portuguese question answering system which has been participating at QA@CLEF since 2004.  ...  We also evaluated the second and third best answers returned by Esfinge. This evaluation showed that when Esfinge answers correctly a question, it does so usually with its first answer.  ...  Acknowledgments This work was done in the scope of the Linguateca project, jointly funded by the Portuguese Government and the European Union (FEDER and FSE) under contract ref.

Assessing Factoid Question-Answer Generation for Portuguese (Short Paper)

João Ferreira, Ricardo Rodrigues, Hugo Gonçalo Oliveira, Ricardo Queirós, Pedro Rangel Henriques, Alberto Simões
2020 Symposium on Languages, Applications and Technologies  
We present work on the automatic generation of question-answer pairs in Portuguese, useful, for instance, for populating the knowledge-base of question-answering systems.  ...  of question-answer pairs, which can be seen as baselines; (iii) results of those approaches in the corpus.  ...  Bearing this in mind, we present a new benchmark for question-answer generation (QAG) in Portuguese, followed by two baseline approaches.  ...

The acquisition of answers to yes – no questions in European Portuguese: syntactic, discourse and pragmatic factors

Ana Lúcia Santos
2003 Journal of Portuguese Linguistics  
This paper (i) describes the patterns of answers to yes-no questions in European Portuguese; (ii) presents data illustrating the acquisition of these patterns; (iii) argues that the acquisition of patterns  ...  of answer to yes-no questions in European Portuguese provides evidence for two types of modularity in the acquisition process: modularity of syntax, discourse and pragmatics and modularity within the  ...  Types of answer to yes-no questions in European Portuguese European Portuguese has different ways of presenting a minimal answer to a yes-no question.  ...

First Evaluation of Esfinge – A Question Answering System for Portuguese [chapter]

Luís Costa
2005 Lecture Notes in Computer Science  
In this paper I will start by describing Esfinge -a general domain Portuguese question answering system, and then the strategies I used to participate in the CLEF-2004 QA track.  ...  Esfinge With a question answering system we want, for a given question, that the system be able of returning answers with the help of an information repository.  ...  To a given question, even if we don't know the answer, we can predict the type of expected answer. For example: -A "When?" question implies an answer of type "date".  ...

The Senso Question Answering Approach to Portuguese QA@CLEF-2007

José Saias, Paulo Quaresma
2007 Conference and Labs of the Evaluation Forum  
There is a logic-programming based module that looks for answers within the facts list that unify and validate the question logic form.  ...  The full text collection is indexed and for each question it's done a search, for retrieval of possible relevant documents that may have one answer.  ...  The Portuguese monolingual QA had 200 questions that this system processed, looking for an answer in the texts.  ...

Using Lucene for Developing a Question-Answering Agent in Portuguese

Hugo Gonçalo Oliveira, Ricardo Filipe, Ricardo Rodrigues, Ana Alves, Michael Wagner
2019 Symposium on Languages, Applications and Technologies  
The solution described answers natural language questions based on an indexed list of FAQs. Its adaptation to different domains is a matter of changing the underlying list.  ...  Different configurations of this solution, mostly on the language analysis level, resulted in different search strategies, which were tested for answering questions about the economic activity in Portugal  ...  Conclusion and Future Work We described how the IR library Lucene can be used in the development of a QA agent that finds answers to questions in Portuguese.  ...
