摘　　要：针对传统医疗资源信息检索算法检索效率低、准确率不足,难以实现信息快速检索等问题,文中提出了一种基于动态多尺度变换的资源信息快速检索技术。该技术方案利用多尺度变换中的离散小波变换对待检索的资源信息关键词进行分解,再按照规则推理及语义形式转换在数据库中查找对应检索信息,通过计算检索信息与检索条件之间的相似程度来确定检索结果的有效性,最后再返回满足符合条件的数据。以某医疗人力资源数据集为样本展开的实验结果表明,相较于其他同类信息检索算法,所提算法能够在保证检索响应时间的条件下,使查全率与查准率分别达到91%和95%以上。In response to the problems of low retrieval efficiency,insufficient accuracy,and difficulty in achieving rapid information retrieval in traditional resource information retrieval algorithms,this paper proposes a resource information rapid retrieval technology based on dynamic multi-scale transformation.The technical scheme uses the discrete wavelet transform of multi-scale transform to decompose the resource information keywords to be retrieved,and then searches the corresponding retrieval information in the database according to rule reasoning and semantic form transformation.The validity of the retrieval results is determined by calculating the similarity between the retrieval information,and finally the data that meets the conditions is returned.The experiment results based on a certain human resource data show that compared to other similar information retrieval algorithms,the proposed algorithm can achieve recall and precision rates of over 91%and 95%,respectively,while ensuring retrieval response time.
