Selecting Answers to Questions from Web Documents by a Robust Validation Process

Abstract: Question answering (QA) systems aim at finding answers to question posed in natural language using a collection of documents. When the collection is extracted from the Web, the structure and style of the texts are quite different from those of newspaper articles. We developed a QA system based on an answer validation process able to handle Web specificity. A large number of candidate answers are extracted from short passages in order to be validated according to question and passages characteristics. The valid… Show more

“…Overall, total precision and recall were about 49% and 50% respectively. Next, [13] developed a QAS based on an answer validation process to be able to handle Web specificity. A large number of candidate answers were extracted from short passages in order to be validated according to question and passages characteristics.…”

“…The purposes of this analysis are to determine whether RTE is the best method for answers validation and to know the other methods that have been used before. There are some researchers using method other than RTE such as Rule-Based [10], Similarity Computation [11], Pipeline Processing [12], and Machine Learning approach [13]. Mapping previous studies is required to know the latest and the best techniques in AV.…”

“…No entanto,é possível encontrar na literatura alguns trabalhos relacionados aos sistemas CQA [Lo et al 2016, Chen et al 2015, Hovy et al 2000, Pôssas et al 2005, Song et al 2007, Grappy et al 2011, Aslay et al 2013, Dalip et al 2013, que possuem características que podem ser utilizadas na busca e ordenação de questionários e, portanto, podem ser analisados a partir dessa perspectiva. Por exemplo, trabalhos que analisam a qualidade da resposta a uma determinada pergunta pode ser visto de forma análogo quando a busca por questionáriosé realizada a partir de apenas uma palavra-chave ou de frases.…”

“…Contudo, os trabalhos [16,5,10,19,21,17,9] que tratam a recuperação e ordenação de perguntas utilizam algoritmos voltados apenas para recuperar e ordenar perguntas do tipo aberta. Porém, como pode ser observado neste experimento, questionários de pesquisa possuem em sua maioria perguntas com alternativas (fechadas e de multipla escolha).…”
