Current massively open online courses (MOOCs) are providing several technical challenges for educators. One of these challenges is automated generation of questions, along with the solutions, in order to deal with a large number of students. Geometry is an important part of the high school curriculum. Hence, in this paper, we have focused on the high school geometry domain. We have proposed a f...

This paper introduces a novel evaluation framework for question series and employs it to explore the effectiveness of QA and IR systems at addressing users’ information needs. The framework is based on the notion of recall curves, which characterize the amount of relevant information contained within a fixed-length text segment. Although it is widely assumed that QA technology provides more eff...

In this paper we describe the Question Answering Challenge (QAC), a question answering task, and its first evaluation (QAC1). The project was carried out as a task of the NTCIR Workshop 3 in October 2002. One objective of the QAC was to develop practical QA systems in a general domain by focusing on research relating to user interaction and information extraction. Our second objective was to de...

In this paper we describe a question answering task, called Question Answering Challenge (QAC), and its first evaluation (QAC1). This was carried out as a task of NTCIR Workshop 3 in October 2002. In QAC, we aimed to encourage the development of practical QA systems in a general domain and focus on research of user interaction and information extraction. Developments of evaluation method of que...
