In this paper, we introduce a novel knowledge-based word-sense disambiguation (WSD) system. In particular, the main goal of our research is to find an effective way to filter out unnecessary information by using word similarity. For this, we adopt two methods in our WSD system. First, we propose a novel encoding method for word vector representation by considering the graphical semantic relationships from the lexical knowledge bases, and the word vector representation is utilized to determine the word similarity in our WSD system. Second, we present an effective method for extracting the contextual words from a text for analyzing an ambiguous word based on word similarity. The results demonstrate that the suggested methods significantly enhance the baseline WSD performance in all corpora. In particular, the performance on nouns is similar to those of the state-of-the-art knowledge-based WSD models, and the performance on verbs surpasses that of the existing knowledge-based WSD models. 相似文献

The purpose of this study was to develop a program to help cultivate divergent thinking in mathematics based on open-ended
problems and to investigate its effect. The participants were 398 seventh grade students attending middle schools in Seoul.
A method of pre- and post-testing was used to measure mainly divergent thinking skills through open-ended problems. The results
indicated that the treatment group students performed better than the comparison students overall on each component of divergent
thinking skills, which includes fluency, flexibility, and originality. The developed program can be a useful resource for
teachers to use in enhancing their students’ creative thinking skills. An open-ended approach in teaching mathematics suggested
in this paper may provide a possible arena for exploring the prospects and possibilities of improving mathematical creativity. 相似文献

Objective
The purpose of this study was to compare effectiveness of different options for de-duplicating records retrieved from systematic review searches.Methods
Using the records from a published systematic review, five de-duplication options were compared. The time taken to de-duplicate in each option and the number of false positives (were deleted but should not have been) and false negatives (should have been deleted but were not) were recorded.Results
The time for each option varied. The number of positive and false duplicates returned from each option also varied greatly.Conclusion
The authors recommend different de-duplication options based on the skill level of the searcher and the purpose of de-duplication efforts. 相似文献4.

The purpose of this randomized experiment was to compare the performance of high-, average-, and low-achieving middle school
students who were assessed with parallel versions of a computer-based test (CBT) or a paper-pencil test (PPT). Tests delivered
in interactive, immersive environments like the CBT may have the advantage of providing teachers with diagnostic tools that
can lead to instruction tailored to the needs of students at different achievement levels. To test the feasibility of CBT,
students were randomly assigned to the CBT or PPT test conditions to measure what they had learned from an instructional method
called enhanced anchored math instruction. Both assessment methods showed that students benefited from instruction and differentiated
students by achievement status. The navigation maps generated from the CBT revealed that the low-achieving students were able
to navigate the test, spent about the same amount of time solving the subproblems as the more advanced students, and made
use of the learning scaffolds.

Forward citations of patents have been used extensively to capture the impact of technological knowledge. However, our understanding of the factors shaping patent citation patterns remains limited. One of the main limitations is the lack of scholarly attention paid to the dynamic influences arising from the evolution of technology fields. From an evolutionary perspective, technological impact is not simply determined by the static attributes of a technology itself; it is also dynamically affected by changes in the external conditions. Drawing on this viewpoint, this study suggests a model for understanding patent citation patterns by reflecting the evolution of the technology fields to which each patent belongs. Four such factors are explored: technology cycle time, potential of technological convergence, popularity of the technology field, and technological novelty. Based on the proposed model, we show how expected citation patterns can change as a result of different scenarios for technology field evolution. We conduct a case study of patents in the information technology and healthcare industries to show citation patterns of patents across heterogeneous industries as well as those within an industry. Contributions to the innovation literature and research investment decisions are discussed. 相似文献

The purpose of this study was to examine: (a) the role of teacher talk in promoting peer interaction, (b) the adequacy of
social IEP objectives to reflect children’s social functioning and guide provision of teacher talk, and (c) differences in
children’s peer interaction and teacher talk in inclusive and segregated settings. Thirty children with disabilities and their
teachers participated. Overall, we observed low rates of teacher talk thought to support peer interaction; however, when teachers
verbally facilitated peer interaction, children were observed interacting more frequently with peers. Children’s social IEPs
accurately reflected their current level of social functioning. However, the social IEPs appeared to fail to influence teacher
intervention. Finally, children with disabilities in inclusive settings interacted with peers more than children in segregated
settings, even though there was no significant difference in amount of teacher talk in the two settings. 相似文献

Educational assessment in the Republic of Korea reflects social and cultural perspectives, as most assessments are considered as a ‘gatekeeper’ of one’s success in life, in terms of entering an elite school or having a better career. This paper presents a profile of the education system, especially focusing on the college entrance examination system in the Republic of Korea, and discusses the washback effect of the high-stake exam, the College Scholastic Ability Test, on stakeholders and the entire society. Furthermore, this paper will discuss the ways to improve the education policy, particularly the college entrance system, with emphasis on implications for future assessment reform from a standardised high-stake test to move towards the formative assessment. 相似文献

This paper addresses synchronization problem for discrete-time complex dynamical networks with interval time-varying delays. In order to achieve the synchronization, a feedback controller subjected to randomly occurring perturbations will be considered. The randomly occurring perturbations are assumed to belong to the Binomial sequence. By constructing a suitable Lyapunov–Krasovskii functional, and utilizing reciprocally convex approach and Finsler?s lemma, the synchronization criteria for the networks are established in terms of linear matrix inequalities (LMIs) which can be easily solved by various effective optimization algorithms. The networks are represented by the use of Kronecker product technique. The effectiveness of the proposed methods will be verified via numerical examples. 相似文献
