数字图书馆书籍资源质量评价仿真

摘要

In this paper,we propose a quality evaluation method of book resource in the digital library based on the analytic hierarchy process (AHP).Firstly,the quality grade fuzzy subset of book resource was built,integrated with the fuzzy theory according to the characteristic of digital library.Then,the fuzzy indexes which map the evaluated book resource quality was quantized using the subset and the indexes were synthesized to influence the book resource quality in the digital library.Moreover,the evaluation index weight was confirmed using the AHP and the evaluation index weight was determined according to the overall hierarchical ranking of resource quality.Finally,we built the fuzzy evaluation matrix of resource quality evaluation and completed the quality evaluation of book resource on this basis.The simulation results show that the method has higher evaluation precision.It provides powerful basis for improving the book resource quality in digital library.%对数字图书馆书籍资源质量进行准确评价,可对数字图书馆书籍资源有明确的认识,指定相关购书计划提高书籍质量.进行书籍资源质量评价时,应准确计算图书馆书籍资源质量评价指标权重,组建资源质量评价模糊评价矩阵完成评价,传统方法通过从主动错误、被动错误2个不同的角度出发组建数字图书馆书籍资源质量模型完成评价,但是不能对图书馆书籍资源质量评价指标权重进行准确计算,无法组建资源质量评价模糊评价矩阵,存在质量评价误差大的问题.提出一种基于层次分析法的数字图书馆书籍资源质量评价方法.上述方法先根据数字图书馆的特点,融合于模糊理论构造图书馆书籍资源质量等级模糊子集,利用上述子集将映射被评书籍资源质量的模糊指标进行量化,并将影响数字图书馆书籍资源质量各指标进行综合,然后利用层次分析法确定图书馆书籍资源质量评价指标权重,根据资源质量层次总排序确定图书馆书籍资源质量评价指标权重,组建资源质量评价模糊评价矩阵,以此为依据完成对数字图书馆书籍资源质量评价.仿真结果表明,所提方法评价精确度较高,为更好地提升数字图书馆书籍资源质量提供了有力的依据.
