| Along with education's development, various universities also positively develop the students'teaching commented work. The direct aim of students'teaching commented is to appraise teachers'work effects, on the other hand, the more important purpose is get the summary of teaching experience to enhances teaching quality. The traditional students'teaching commented existences many qualitative targets that causes the generalized analysis and operation with difficulty.In fact we should comment the result from many angles. Now we have two questions: on the one hand, we should consider as far as possible many targets; on the other hand, more targets will complicate the question. Simultaneously, many targets exist on relations with each other. In order to deal with the above questions, using the PCA method to analysis many targets, thus get some major targets.Because of huge data, we can use parallel computing to solve the problem of system's speed. With the development of high speed of Internet, parallel computing can reasonable use the school's network resources to help the students'teaching commented.Using the PCA parallel algorithm, will develop teaching commented system based on this. This system mainly uses to deal with the targets of teaching commented. Taking out several major targets from the existing target to reduce the workload of teaching commented and reduce the difficulty of anglicizing the teaching commented's result. On the basis of major targets, the system will classify the data by K-Means algorithm to cause the teaching commented separated from the manual operation truly and raise teaching commented's efficiency and fairness. This article uses the object-oriented technology to achieve the system analysis and design. We will get the static construction based on the object level, the structure level, the subject level, the attribute level and the event level. Finally, obtains the example view by the static construction to express the system function's high-level logistic model. We will achieve the parallel computing principle component analysis– based teaching commented system and use it in school's students'teaching commented work. |
