A Systematic Review of Automatic Question Generation for Educational Purposes

Ghader Kurdi, Jared Leo, Bijan Parsia, Uli Sattler, Salam Al-Emari
2019 International Journal of Artificial Intelligence in Education  
To reduce the expenses associated with manual construction of questions and to satisfy the need for a continuous supply of new questions, automatic question generation (AQG) techniques were introduced.  ...  This, in turn, hinders and slows down the use of educational activities (e.g. providing practice questions) and new advances (e.g. adaptive testing) that require a large pool of questions.  ...  Free-response questions are more prevalent among studies using text, with 21 studies focusing on this question type, 18 on multiple-choice, three on both freeresponse and multiple-choice questions, and  ...

A Survey and Analysis of Current CAPTCHA Approaches

Narges Roshanbin, James Miller
2013 Journal of Web Engineering  
Two fundamental issues with CAPTCHAs are usability and robustness. It is important for a CAPTCHA to be both legible for humans and strong against malicious computer programs.  ...  Lack of security and usability in CAPTCHAs designed to protect popular websites such as Gmail and Yahoo mail, with almost 500 million users in July 2011, would cause huge problems.  ...  The random question "which word is connected to center by a line marked with a circle?" is asked in this example. It is easy for human but difficult for computers to answer this question [63] .  ...

CNN-based framework for classifying temporal relations with question encoder

Yohei Seki, Kangkang Zhao, Masaki Oguni, Kazunari Sugiyama
2021 International Journal on Digital Libraries  
To overcome this problem, we propose a novel framework that incorporates prior information by employing awareness of events and time expressions (time-event entities) with various window sizes to focus  ...  We refer to this module as "question encoder." In our approach, this kind of prior information can extract task-related information from simple sentence embedding.  ...  Acknowledgements This work was partially supported by a Japanese Society for the Promotion of Science Grant-in-Aid for Scientific Research (B) (#19H04420).  ...

Pretrained Transformers for Text Ranking: BERT and Beyond

Andrew Yates, Rodrigo Nogueira, Jimmy Lin
2021 Proceedings of the 14th ACM International Conference on Web Search and Data Mining  
The goal of text ranking is to generate an ordered list of texts retrieved from a corpus in response to a query for a particular task.  ...  This survey provides an overview of text ranking with neural network architectures known as transformers, of which BERT is the best-known example.  ...  However, there remain many open research questions, and thus in addition to laying out the foundations of pretrained transformers for text ranking, this survey also attempts to prognosticate where the  ...
