A recent “third wave” of neural network (NN) approaches now delivers state-of-the-art performance in many machine learning tasks, spanning speech recognition, computer vision, and natural language processing. Because these modern NNs often comprise multiple interconnected layers, work in this area is often referred to as deep learning. Recent years have witnessed an explosive growth of research into NN-based approaches to information retrieval (IR). A significant body of work has now been created. In this paper, we survey the current landscape of Neural IR research, paying special attention to the use of learned distributed representations of textual units. We highlight the successes of neural IR thus far, catalog obstacles to its wider adoption, and suggest potentially promising directions for future research. 相似文献

E-books have increasingly penetrated the academic world. However, despite efforts from Vietnamese universities and colleges to establish and broaden their e-books collection, students seem reluctant to use these digital books. This study aims to examine the barriers to using e-books in libraries among Vietnamese students. Data were obtained from 355 undergraduate students who were interested in e-books. The findings demonstrate that some key barriers impeding students from using e-books include the lack of computers and e-books in libraries, limited information and knowledge about e-books and their preference of using print books. Interestingly, female students tend to perceive the barriers to be stronger than their male counterparts. This study’s findings have important implications for universities, libraries and publishers who seek to promote e-books to students. 相似文献

Higher education textbooks sales account for a significant portion of the overall book market. This study makes an important contribution to the extant literature by examining students’ purchase of original textbooks in a developing market, Vietnam. Notably, it seeks to investigate why students do not purchase original textbooks as well as the difference in purchase behavior between different groups of students. The findings reveal that some key obstacles to students’ purchase behavior include high prices, insufficient availability, low perceived value, and the emergence of pirated textbooks. Another notable finding is that senior students who are female tend to purchase more textbooks. In light of these findings, marketing strategies are suggested for publishers, bookstores and universities who aim to promote the sales and consumption of original textbooks. 相似文献

Cooking and tasting chicken soup in three different pots of very different size serves to demonstrate that it is the absolute sample size that matters the most in determining the accuracy of the findings of the poll, not the relative sample size, i.e. the size of the sample in relation to its population. 相似文献

There is a significantly growing interest in publishing in international scholarly journals in Vietnam. On the one hand, Vietnamese researchers can be potential authors of interesting articles that provide new insights into the emerging economic context. On the other hand, they can be target consumers and subscribers of journals in their quest for academic and practical knowledge. This paper aims to propose marketing initiatives for publishers and editors who seek to promote their journals to researchers in emerging countries, particularly Vietnam. These marketing solutions build upon an understanding of barriers for researchers in international publications. 相似文献

In order for Vietnam to seek better international integration into an increasingly globalised world, the Vietnamese Government has launched educational reforms requiring teachers to adopt ‘Western’ constructivist pedagogies. This paper reports on an action research study in a Vietnamese teacher training institution which found that Vietnamese student teachers were willing to accommodate and accept change and were often very enthusiastic about the ‘Western ideas’ of teaching and learning, but that their unquestioning respect for the authority of their tutors remained firmly fixed. The data also showed that the students’ tutors had a relatively limited exposure to the ‘Western theories’ and their implications and therefore did not model or demonstrate the theories effectively. The paper draws on these findings to argue that the focus for transforming Vietnamese teachers’ practice should be on promoting the responsibility of teacher educators to introduce student teachers to new ideas about the processes of teaching and learning. This strategy is likely to be more supportive of student teachers’ development as it allows them to separate the processes of teaching from culturally dominant beliefs about roles which are part of their established identities. 相似文献

As part of a wide-scale education reform, Hong Kong schools have been focusing on the creation of ‘no loser’ classrooms that support learning for all students (Education Commission 2000). This article examined both groups of ethnic minority and Chinese students’ perception of assessment practices and the extent to which classroom practice is consistent with preferred assessment practices. The 11 items of assessment practices list, developed by Brown et al. (2009a), were used to investigate the perceptions of 1,518 student respondents from 15 primary and secondary schools, in which a large number of ethnic minority students were accommodated. A confirmatory factor analysis showed that the respondents in the group from secondary schools viewed teacher-dominated assessment as the most important assessment practice in the model examined (Brown et al. Learning and Instruction, 19(2), 97–111, 2009b) whereas those in the primary group considered teacher-student interactive assessment as the most important practice. Also, three perceptions of assessment practices of ethnic minority students were confirmed: teacher-dominated, student-centred and teacher-student interactive. Amongst them, the most preferred one was the teacher-student interaction assessment practice. Finally, the implications of the creation of a no loser classroom for all students are discussed. 相似文献

Significant limitations have emerged in America's science training pipeline, including inaccessibility, inflexibility, financial limitations, and lack of diversity. We present three effective programs that collectively address these challenges. The programs are grounded in rigorous science and integrate through diverse disciplines across undergraduate, graduate, and postdoctoral students, and resonate with the broader community. We discuss these models in the context of current economic constraints on higher education and the urgent need for our institutions to recruit and retain diverse student populations and sustain the successful American record in scientific education and innovation. 相似文献
