Direct questions such as “Who saw Mary?” intuitively request for a certain type of answer, for instance a noun phrase “John” or a quantified noun phrase such as “A man”. Following the structured meaning approach to questions, we propose an analysis of wh-questions in typelogical grammar that incorporates the requirement for a certain type of answer into the type assigned to wh-phrases. Interest...

Product compatibility and their functionality are of utmost importance to customers when they purchase products, and to sellers and manufacturers when they sell products. Due to the huge number of products available online, it is infeasible to enumerate and test the compatibility and functionality of every product. In this paper, we address two closely related problems: product compatibility an...

Recently, quantitative notions of relevance have been proposed for questions and assertions and, based on an assumption of optimal relevance, used for linguistic applications. BarHillel and Carnap’s (1953) notion of informativity (their ‘inf’ value) has already been used in traditional pragmatics of natural language; Merin (1999a,b) proposes that the relevance of a proposition q should be seen ...

With the development of Web 2.0 technologies, social question and answering has become an important venue for individuals to seek for information that are important to their everyday lives. While prior literatures studying social question answering have suggested the possibility of routing questions to potential answerers for assistance, still little is known about how effective these question ...

Questions and answers about incapacitation abound in all discussions about criminal justice policy. They are among the most pressing of all research issues, yet estimates about the incapacitation effect on crime vary considerably, and most are based on very old and incomplete estimates of the longitudinal pattern of criminal careers. This paper provides an overview of the incapacitation issue, ...

This report describes the system developed at the University of Rome “La Sapienza” for the TREC-2006 question answering evaluation exercise. The backbone of this QA system is linguistically-principled: Combinatory Categorial Grammar is used to generate syntactic analyses of questions and potential answer snippets, and Discourse Representation Theory is employed as formalism to match the meaning...

For E-learning such as web based teaching (WBT), in order to reduce the cost of making questions, a computer system that generates questions and answers is desirable. However, such a system does not always generate them correctly. As a result, human instructors have to check the generated questions and remove the errors. In this paper, we propose a technique for removing errors in the generated...

Background: Peer to peer learning is a well-established learning modality which has been shown to improve learning outcomes, with positive implications for clinical practice. Surgical students from across Ireland were invited to upload learning points daily while paired with their peers in a peer-reviewing process. This study was designed to assess content accuracy and evaluate the benefit of t...

In this work we propose to apply a participatory design process for developing mobile games focused on learning and communication of autistic children. This study employs a game to help people with autism and describes the complete design process used in this research. As a result of the design process was possible to note the necessity to allow high customization and personalization of digital...
