基于N层向量空间模型的装备IETM数据查询

IETM Data Retrieval of Equipment Based on N-level Vector Model

为了提高IETM数据查询的准确率,通过对数据模块编码层与XML内容层进行分析,结合N层向量空间模型查询算法,从IETM数据模块编码层中的型号识别码、系统层次码、信息码以及数据模块内部数据信息入手,提出了一种基于N层向量空间模型的装备IETM数据查询算法,并通过IETM实例验证了该算法的正确性与实用性。

Aiming at improving the accuracy of IETM data retrieval,through analyzing the levels of data module code and XML content,in combination with the retrieval algorithm of N-level vector space model, this paper presents a data retrieval method of IETM based on N-level vector space model from model iden-tification code,standard numbering system,information code of data module coding layer and the infor-mation in the data module.At last,it proves the correctness and practicability of the algorithm in accord-ance with IETM instance.
