While both theoretical and empirical studies of question-answering have revealed the inadequacy of traditional definitions of Ve*-no questions (YNQs), little progress has been made toward a more satisfactory redefinition. This paper reviews the limitations of several proposed revisions. It proposes a new definition of YNQs baaed upon research on a type of conversational irnpIieature, termed her...

In this paper, we propose to analyze the informativeness of questions, in the context of ‘inquiry games’, where a player, Inquirer, intends to establish a certain conclusion by means of a combination of reasoning and interrogation, using information (answers) from other players, Sources. This paper is one step toward a precise game-theoretic foundation for these games, which where suggested by ...

An indirect answer to! a Yes-No question conversationally implicates the speaker's evaluation of the truth of the questioned proposition. We present the approach to generation used in our implemented system for generating and interpret~ing indirect answers to Yes-No questions in English. Generation of a discourse plan is performed in two phases: content planning and plan pruning. During content...

This paper investigates a solution to yes/no question answering, which can be mapped to the task of determining the correctness of a given proposition. Generally it is hard to obtain explicit evidence to conclude a proposition is false from an information source, so we convert this task to a set of factoid-style questions and use an existing question answering system as a subsystem. By aggregat...

Antidepressants are widely used in the treatment of bipolar depression despite relatively meagre evidence for their efficacy and significant concerns that their prescription can precipitate an acute affective switch into mania/hypomania and that long-term administration can lead to mood instability. Therefore, the use of antidepressants to treat bipolar depression is an important but contentiou...

Yes-No answers have traditionally posed major difficulties in speech recognition: the amount of signal is too short and may lead to mis-recognition. We think that the speech signal itself, that is, intonation (F0 and energy) are not enough to fulfil this task. When the information the signal can provide is so little, we must look for other sources. This paper analyzes intonation and gestures to...

Streptococcus pneumoniae (S. pneumoniae) is one of the leading pathogens that cause community-acquired infections. It has accumulated genetic mutations throughout its evolution, and at present more than 90 different serotypes of S. pneumoniae are known. Serotypes are identified based on the polysaccharide capsule that surrounds the cell wall. Despite the high number of serotypes, most cases of ...
