潜在语义分析在关键词—叙词对照系统构建中的应用

Application of Latent Semantic Analysis in the Construction of Keyword- Descriptor Comparison System

文章通过构建关键词—叙词矩阵,利用潜在语义分析技术,实现了关键词与叙词的自动对照。在此系统中,当用户输入关键词后,该系统能够自动提示出与之相关的叙词,辅助标引人员和检索用户根据实际情况进行选择。实验结果表明,该方法取得了良好的效果。

This paper achieves tile automatic comparison of keyword and descriptor by constructing keyword-descriptor matrix and using latent semantic analysis technology. In this system, when users input a keyword, the system will automatically prompt the related descriptors, which assists indexer or retrieval user in choosing according to the actual situation. Finally, the experiment re- sults show that the proposed method has a good effect.
