Based on K-Means algorithm and agglomerative hierarchical clustering algorithm, improvement was made regarding the use of clustering algorithm in the application of text mining. It was verified that the accuracy and efficiency of hot topic detection had been enhanced via vector representation of the text, text similarity calculation, and implementation of clustering algorithm.
As a new information acquisition and processing technology, wireless sensor networks can achieve tasks with complex large-scale monitoring and tracking in wide range of applications, but the localization for node itself is the basis of most applications. APIT is a major localization algorithm of ranged free algorithms, but the algorithm has the problems of big localization errors and low coverage...
In order to meet the requirements of modern society, students in business related specialties need to possess practical ability, decision-making ability and the tools of mastering knowledge. Experimental teaching, as a kind of teaching reform that adapts the need of the society, starts to be used widely in business colleges. However, there are some problems and difficulties in business experimental...
As an innovative learning method, web-based learning has gain increasingly attention by both of the instructors and the students. However, the assessment system involved in web-based learning is still far from perfect. According to the principles of university web-based learning, which focus on the learning process, diversification of evaluation methods and evaluation objects, this study builds an...
A teaching development board system based on MCS-51 single chip processor is introduced in this paper. The software and hardware exploitation process is described in detail. The focus of the study is designing the peripheral hardware circuits and corresponding software program based on the internal structure of MCS-51. The system has complete functions and it mainly includes I/O subsystem, data collecting...
Experimental teaching is widely applied in the fields of natural science, engineering, ecology and social science etc. It is also witnessed the increasingly penetrating into business related teaching and training. In particular, simulation based experiment has got immense attention in many management and economics schools of the universities. Simulation based experimental teaching helps the students...
Compared with traditional teaching, case study method of teaching is an interactive learning approach, which changes the role of students from passive participants to active learners. Modern education has been expedited by digital tools, such as Web-based learning environment. How to align the advantage of network environment with the case study teaching method is a new challenge. The paper analyses...
