We address the challenge of automatically generating questions from reading materials for educational practice and assessment. Our approach is to overgenerate questions, then rank them. We use manually written rules to perform a sequence of general purpose syntactic transformations (e.g., subject-auxiliary inversion) to turn declarative sentences into questions. These questions are then ranked ...

The queries to a practical Question Answering (QA) system range from keywords, phrases, badly written questions, and occasionally grammatically perfect questions. Among different kinds of question analysis approaches, the pattern matching works well in analyzing such queries. It is costly to build this pattern matching module because tremendous manual labor is needed to expand its coverage to s...

While exam-style questions are a fundamental educational tool serving variety of purposes, manual construction is complex process that requires training, experience and resources. Automatic question generation (QG) techniques can be utilized to satisfy the need for continuous supply new by streamlining their generation. However, compared automatic answering (QA), QG more challenging task. In th...

Asking questions is an important ability for a chatbot. Although there are existing works on question generation with a piece of descriptive text, it remains to be a very challenging problem. In this paper, we consider a new question generation problem which also requires the input of a target aspect in addition to a piece of descriptive text. The key reason for this new problem is that it has ...

Recent research has led to the emergence of ontology-based question generation and aims to benefit instructors by providing support and intelligent assistance for the automatic generation of questions. However, existing ontologies are not designed mainly for this purpose, and the concern is that an ontology will not be competent enough to act as a semantic source for the question generation pro...

Abstract With the swift growth of information over past few years, taking full benefit is increasingly essential. Question Answering System one promising methods to access this much information. The lacks humans’ common sense and reasoning power cannot identify unanswerable questions irrelevant questions. These are answered by making unreliable incorrect guesses. In paper, we address limitation...

The flipped classroom is a relatively new approach to undergraduate teaching in science. This approach repurposes class time to focus on application and discussion; the acquisition of basic concepts and principles is done on the students' own time before class. While current flipped classroom research has focused on student preferences and comparative learning outcomes, there remains a lack of ...
