Research On Evaluation Of Undergraduates' Comprehensive Quality Based On Multi-source Information Fusion

It is a complicated problem to evaluate the quality of the undergraduates according to their different majors and characteristics when higher education is becoming popular, globalized and value-diversified. It is unable to master all the necessary and relevant knowledge or information to evaluate the quality, and make a reasonable evaluation depending on personal energy, knowledge, experience and wisdom. Evaluators have to integrate multi-source information in the procedure of evaluating, from experts as well as undergraduates training process is closely related to the composition of the evaluation group to evaluate the wisdom of relying on groups, information and knowledge to solve problems. Evaluators have to deal with information from different sources. It was used to evaluate knowledge of the structure due to the evaluators, judging the level and personal preferences and other subjective factors and the overall quality of undergraduates by the evaluation group which made of experts and relevant personnel closely to undergraduates training.The Main problems on evaluating the comprehensive quality of the undergraduates were divided into three aspects. Firstly, the problem of establishing stable evaluation index system and the singleness of evaluation objects. Whether the object of evaluation is a freshman, upperclassman or graduates, regardless of evaluation of the main teachers, counselors, administrators or school personnel, there is no distinction for index indicators and therefore not suited to evaluate the result of quality to personalized evaluation requirements. Secondly, the evaluation process is static and their growth process was not considered, and no feedback is given for the result of the evaluation. So the result could not reflect the growth process of the undergraduates and it's hard to put forward the pertinent incentive policies. Thirdly, the evaluation result is too simple to reflect of the true level of quality of students.Given the above problems, after examined the existing undergraduates" comprehensive evaluation system, the paper proposed the framework for Comprehensive Evaluation of Undergraduates, furthermore. Information Fusion Theory. Agent Technology were also used in the evaluation process of comprehensive multi-source data acquisition, data fusion, assessment index and weight, personalized comprehensive evaluation model were made of the complete theoretical system for comprehensive evaluation for undergraduates'quality, which provided theoretical support. Important conclusions were used to guide the university personal qualities education and improve the quality of evaluation and management with strong practical significance. The main contents of the paper are as follows:Firstly, existed evaluation system problems were analyzed on the quality of undergraduate's through the evaluation objectives, evaluation methods and the literature review of evaluation index, combined with the status of evaluation management of the quality of university undergraduates, it was pointed out that evaluation criteria for a variety of types of talent, a variety of specifications, a variety of levels, was to avoid using the same one for thousands of students, to fully exploit the potential quality of students, and appraised subject pluralism, appraised in contents and appraise method variety.Secondly, the paper proposed the establishment of personalized, dynamic and comprehensive quality assessment system, a clear evaluation of different subject, different evaluation objects to customize the necessity and feasibility evaluation. Furthermore a framework was built for comprehensive evaluation from the model, application and implementation of the three dimensions of undergraduates. The first dimension is the model dimension, the main idea of that thesis, including the analysis of multi-source data source; multi-source data fusion method to establish the corresponding database, model base; determined by binary semantic fusion model assessment index, index weight, and further establish the evaluation model customization. The second dimension is the implementation of the dimension. multi-Agent technology, the establishment of multi-Agent system including Information Agent, Information Fusion Agent. Evaluation Agent, Management Agent and Multi-Agent System Interface Agent, individualized evaluation process simulation. The third dimension is the application of the dimension, mainly considering the application of the subject and object. The main object of different evaluation models can be customized for different objects.Thirdly, considered the quality of the comprehensive evaluation of the data source is multi-source heterogeneous, both from the knowledge of all kinds of different people, but also from different information systems data; evaluation method is diverse. Thus a multi-source information fusion method was used on multi-source data, a variety of methods to establish a comprehensive database of information fusion, model base, provided information infrastructure for the evaluation.Fourth, in the study on the quality of evaluation of the undergraduates, considered a lot of subjective quality assessment information, fuzzy information, it were avoided to loss of information, first objective evaluation, subjective evaluation of standardized evaluation of information for further data analysis were a valid target data; and then 2-tuple linguistic representation, information fusion operator were used for the evaluation of the quality of the views of experts on group decision making; the paper calculated a comprehensive evaluation of the index weight at last.Fifthly, a customized evaluation model on the quality of students was made, so the detailed evaluation of the individual and the individual evaluation of the selection process were described. The unbalanced, unified assessment was avoided and the student-centered evaluation based on personalized ideas was reflected for using dynamic quality of undergraduate and personalized evaluation.The innovations were reflected in the following three aspects:Firstly. the emphasis on student's personality, people-oriented concept, the introduction of the theory of Multi-source Information Fusion and Multi-agent Technology into the Comprehensive Evaluation of the quality of undergraduates, the establishment of the model dimension, the application of three-dimensional dimensions and implementation of the dimension framework for Comprehensive Evaluation of undergraduates, which provided a guideline to establish comprehensive quality evaluation system.Secondly, a comprehensive evaluation of the expert group decision quality advice and a comprehensive evaluation system to determine the index weight was given to the usage of information fusion methods to multi-source data while a comprehensive variety of evaluation methods and usage of multiple information fusion operator and 2-tuple linguistic representation method, which provided a theoretical basis for evaluation.Thirdly, considered the different evaluation of the main objects, the establishment of a personalized evaluation model tailored was used for different types of education of undergraduates at different stages and different evaluation objectives, with different evaluation models, evaluation criteria to be evaluated. The evaluation model was not only used for the quality of undergraduates navigation training, but also for the quality of university education and more focused management, which would be more proactive and effective.
