摘要:
Taxonomy merging is an important work to provide a uniform schema for several heterogeneous taxonomies. Previous studies primarily focus on merging two taxonomies in a specific domain, while the merging of multiple taxonomies has been neglected. This article proposes a taxonomy merging approach to automatically merge multiple source taxonomies into a target taxonomy in an asymmetric manner. The approach adopts a strategy of breaking up the whole into parts to decrease the complexity of merging multiple taxonomies and employs a block-based method to reduce the scale of measuring semantic relations between concept pairs. In addition, for the problem of multiple inheritance, a method of topical coverage is proposed. Experiments conducted on synthetic and real-world scenarios indicate that the proposed merging approach is feasible and effective to merge multiple taxonomies. In particular, the proposed approach works well in the aspects of limiting the semantic redundancy and establishing high-quality hierarchical relations between concepts.

摘要:
The algebraic methods represented by Wu's method have made significant breakthroughs in the field of geometric theorem proving. Algebraic proofs usually involve large amounts of calculations, thus making it difficult to understand intuitively. However, if the authors look at Wu's method from the perspective of identity,Wu's method can be understood easily and can be used to generate new geometric propositions. To make geometric reasoning simpler, more expressive, and richer in geometric meaning, the authors establish a geometric algebraic system (point geometry built on nearly 20 basic properties/formulas about operations on points) while maintaining the advantages of the coordinate method, vector method, and particle geometry method and avoiding their disadvantages. Geometric relations in the propositions and conclusions of a geometric problem are expressed as identical equations of vector polynomials according to point geometry. Thereafter, a proof method that maintains the essence of Wu's method is introduced to find the relationships between these equations. A test on more than 400 geometry statements shows that the proposed proof method, which is based on identical equations of vector polynomials, is simple and effective. Furthermore, when solving the original problem, this proof method can also help the authors recognize the relationship between the propositions of the problem and help the authors generate new geometric propositions.

摘要:
The application of Information and Communication Technology (ICT) in teaching can improve the teaching quality and efficiency. Exploring the differences in mathematic teachers' ICT application level can not only better help us understand the status of overall mathematic teachers' ICT application level, but also promote the development of ICT-based teaching in mathematic by discovering the shortcomings. This study explored the differences of K-12 mathematic teachers' ICT application level from three aspects-teacher's attitude towards ICT (TAT), ICT instruction in classroom (IIC) and ICT effects (ICE). A survey research design was used for the study, and 918 K-12 mathematic teachers participated in the study. The ANOVA results showed that, there were significant differences in TAT and ICE between primary school teachers and secondary school teachers, while there were no significant differences between rural school teachers and urban school teachers. As for IIC, on the other hand, there was significant differences between primary school teachers and secondary school teachers and there were significant differences between rural school teachers and urban school teachers. According to the results, some implications were proposed to improve K-12 mathematic teachers' ICT application level.
摘要:
In China, teachers’ ability to adopt information and communication technology (ICT) when teaching is far from satisfying. Previous studies on teachers’ ability to integrate ICT and teaching in China ignored the factors in the process of teachers’ ICT application and lacked the systematic analysis of the factors. ICT application is affected by complex factors and thus needs to be systematically explored. This study surveyed 3730 Chinese primary and secondary school teachers, and adopted the environment-based design, exploratory factor analysis, confirmatory factor analysis, and structural equation modeling to analyze the factors influencing teachers’ usage of ICT to develop teaching activities and proposed a model of the influencing factors of ICT usage. This model indicated that application willingness, application frequency, ICT-based teaching competence, helpfulness degree and application context are the five major factors that influence teachers’ usage of ICT to develop high-quality teaching activities. According to the status of teachers’ ICT application in China, this study suggested strengthening teachers’ willingness and enriching application contexts of ICT. Implications of this study will be discussed.

摘要:
With the rapid development of ICT and the increasing emphasis on ICT in education in many countries, ICT in teaching has become more and more significant. The related studies of supporting environment of ICT in university teaching mainly focused on the current situation and improvement strategies. They seldom studied the composition of supporting environment of ICT in university teaching from a systematic perspective. And a unified system model of supporting environment was scarce. The study divided the supporting environment of ICT in teaching into three categories of hardware environment, software environment and potential environment by analyzing the environmental factors of ICT in Chinese university teaching, and built the evaluation model of supporting environment of ICT in university teaching. Based on the model, the study evaluated the construction of supporting environment of ICT in teaching of the selected university in China to help make decisions for development of ICT in university teaching. This study could provide some reference for the related research and development of supporting environment of ICT in Chinese university teaching.
