摘要：利用数据库特色功能,从结构检索、信息分析及号码检索三个方面研究了提高查新检索质量的方法。研究表明,对一些课题,利用数据库提供的特色功能可以提高查新检索结果的全面性和相关性。对结构检索,选择合适的基本结构成为提高检索质量的关键;号码检索与词检索共同使用、利用合适的信息分析词都可以有效地提高查新检索质量。
By mining the features of the database, the methods to improve information retrieval effectiveness of novelty retrieval were proposed from structure search, information analysis, and number search. As a result, for some novelty retrievals, using the database features can improve search relevance and comprehensiveness. For the structure search, it is important for improvement of information retrieval effectiveness to choose the substructure. Moreover, as to some databases which can search using the number or can provide the information analysis, the combination of the number search and term search, choose of words for information analysis are effective ways to improve the retrieval effectiveness.
