Answer type validation in question answering systems
In open domain question-answering systems, numerous questions wait for answers of an explicit type. For example, the question “Which president succeeded Jacques Chirac?” requires an instance of president as answer. The method we present in this article aims at verifying that an answer given by a system corresponds to the given type. This verification is done by combining criteria provided by di...
متن کاملLanguage-independent Probabilistic Answer Ranking for Question Answering
This paper presents a language-independent probabilistic answer ranking framework for question answering. The framework estimates the probability of an individual answer candidate given the degree of answer relevance and the amount of supporting evidence provided in the set of answer candidates for the question. Our approach was evaluated by comparing the candidate answer sets generated by Chin...
متن کاملAnswer Formulation for Question-Answering
In this paper, we describe our experimentations in answer formulation for question-answering (QA) systems. In the context of QA, answer formulation can serve two purposes: improving answer extraction or improving human-computer interaction (HCI). Each purpose has different precision/recall requirements. We present our experiments for both purposes and argue that formulations of better linguisti...
متن کاملDoctoral Dissertation Identification of Multi-Sentence Question Type and Extraction of Descriptive Answer in Open Domain Question-Answering
The state-of-art question-answering systems provide the answer to the user by directly extracting the exact answer from a huge amount of documents in large databases or Web pages. On the other hand, many online question-answering services, such as automatic answering services in call centers, Q&A web sites in the Internet, are in operation by restricting the domain of questions, and by utilizin...
متن کاملAnswer Attenuation in Question Answering
Research in Question Answering (QA) has been dominated by the TREC methodology of black-box system evaluation. This makes it difficult to evaluate the effectiveness of individual components and requires human involvement. We have collected a set of answer locations within the AQUAINT corpus for a sample of TREC questions, in doing so we also analyse the ability of humans to retrieve answers. Ou...
