The Research Of Paper In Quality Evaluation Based On Sciencepaper Online

"SciencePaper Online" is a scientific papers website with approved by the ministry of education, hold by the ministry of education science and technology development centers. It's built for some difficulties of research personnel reflected in general, such as paper present difficulties, academic exchanges difficulties, research results convert to realistic productive power difficulties. So it adopt the way that "First issue, After review".Through the research of information extraction techniques, this paper extracted the paper information and the evaluation information of the experts and users to this paper from semistructurized HTML page based on HTML web information extract method, then stored them into database for the follow study of quality evaluation of this paper.Through the comparative analysis between traditional science technology paper quality evalution method and network technology paper quality evaluation method, this paper concentrated the advantages of all methods and data of "SciencePaper Online" website, design a paper quality evaluation method adopt "SciencePaper Online", considered the weights of these index such as expert opinion(namely comprehensive review), the situation of recruit, the author unit, the number of downloaded, collection, recommend, reader recommend and comment in paper quality evaluation. It adopt e function define weights, apply optimal descend gradient method iterated optimal weights to make the error between the objective and expectation is minimum, then use the optimal weights generated by iterative model and linear sums model calculate the paper quality evaluation.This paper takes the papers of nuclear science technical as the example data, calculate paper quality evaluation value by optimal weights generated by iterative model and linear sums model, and make an error analysis. The results confirm that this paper provides a quality evaluation method of suitable for "SciencePaper Online" is feasible.Last, put a statistical analysis for the data of "SciencePaper Online" website before October 2009, and the statistical results also validated the method of this paper put forward is right. Specific statistics content is following:Subject hotpots analysis; The proportion of high quality paper of colleges and universities; The proportion between high quality and low quality paper and development trend.
