The investigation presented in this paper is a novel method in question answering (QA) that enables a QA system to gain performance through reuse of information in the answer to one question to answer another related question. Our analysis shows that a pair of question in a general open domain QA can have embedding relation through their mentions of noun phrase expressions. We present methods f...

background: it is important to learn how to study for different examinations. the objective of the current study is to explore whether the assessment method selection would significantly affect the studying and learning approaches of students. methods: this descriptive-analytical research consisted of 191 first-year undergraduate nursing students from three nursing schools and was conducted dur...

ABSTRACT In this paper, we focus on the "Question-Answer" function of the SOUTO system; the hypermedia authoring system, and classroom activities where learners make hypermedia compositions with SOUTO and discuss their compositions with the function mentioned above. Field tests of the system reveal that; 1. The Question-Answer function reconfigures social relationships in the classroom and thus...

Document or passage retrieval is typically used as the first step in current question answering systems. The accuracy of the answer that is extracted from the passages and the efficiency of the question answering process will depend to some extent on the quality of this initial ranking. We show how language model approaches can be used to improve answer passage ranking. In particular, we show h...

Using elementary techniques, a question named after the famous Russian mathematician I. M. Gelfand is answered. This concerns the leading (i.e., most significant) digit in the decimal expansion of integers 2n, 3n, . . . , 9n . The history of this question, some of which is very recent, is reviewed.

Nagy's question is whether or not every power-bounded operator is similar to a contraction [3]. ("Power-bounded" means that the norms of the positive powers are bounded.) Foguel's answer is no [l]. The purpose of this note is to look at Foguel's ingenious counterexample from a point of view somewhat different from his own. The advantage of the new look is that it is less computational; its draw...
