In this paper,we consider a testing setting where the set of possible definitions of the Implementation Under Test(IUT),as well as the behavior of each of these definitions in all possible interactions,are extensionally defined,i.e.,on an element-by-element and case-by-case *** this setting,the problem of finding the minimum testing strategy such that collected observations will necessarily let us decide whether the IUT is correct or not(i.e.,whether it necessarily belongs to the set of possible correct definitions or not)is studied in four possible problem variants:with or without non-determinism;and with or without more than one possible definition in the sets of possible correct and incorrect *** computational complexity of these variants is studied,and properties such as PSPACE-completeness and Log-APX-hardness are identified.

Wuhan University Journal of Natural Sciences 2006年第1期11卷 313-322页

作者： KUO Tzai-hsing LIN Hsien-tang YUAN Shyan-ming Department of Computer and Information Science National Chiao Tung University Hsinchu 30010 Taiwan China

Due to the maturing of Internet technology, the adaptive testing can be utilized in the web-based environment and the examinee can take the test anywhere and any time. The purpose of the research is to apply item response theory （IRT）, adaptive testing theory and web-service technique to construct an XML format itembank and a system of web- based adaptive testing （WAT） by the framework of threetiered client server distance testing.

Reducing Item Exposure in Computerized adaptive testing Systems Using Automatic Item Generation

引用

Computer Technology and Application 2014年第1期5卷 21-24页

作者： Harutyun Terteryan Department of Computer Systems and Informatics State Engineering University of Armenia Yerevan 1109 Armenia

This paper studies the technics of reducing item exposure by utilizing automatic item generation methods. Known test item calibration method uses item parameter estimation with the statistical data, collected during examinees prior testing. Disadvantage of the mentioned item calibration method is the item exposure; when test items become familiar to the examinees. To reduce the item exposure, automatic item generation method is used, where item models are being constructed based on already calibrated test items without losing already estimated item parameters. A technic of item model extraction method from the already calibrated and therefore exposed test items described, which can be used by the test item development specialists to integrate automatic item generation principles with the existing testing applications.

关键词： Item exposure calibration IRT (item response theory) adaptive testing automatic item generation item model.

Software Reliability Experimentation and Control

引用

Journal of Computer Science & Technology 2006年第5期21卷 697-707页

作者：蔡开元 Department of Automatic Control Beijing University of Aeronautics and Astronautics Beijing 100083 P.R. China

This paper classifies software researches as theoretical researches, experimental researches, and engineering researches, and is mainly concerned with the experimental researches with focus on software reliability experimentation and control. The state-of-the-art of experimental or empirical studies is reviewed. A new experimentation methodology is proposed, which is largely theory discovering oriented. Several unexpected results of experimental studies are presented to justify the importance of software reliability experimentation and control. Finally, a few topics that deserve future investigation are identified.

关键词： software reliability software experimentation software reliability control adaptive testing
