【摘要】：传统观点认为如果检索词包含较多相关主题的术语和使用布尔逻辑运算符将增强检索词的解释性 ,检索时信息检索系统也会产生较多的相关结果。虽然有研究表明普通的Web搜索引擎用户很少键入检索术语和使用的布尔逻辑运算符 ,但这并不能就此说明搜索结果和检索术语与布尔逻辑运算符的运用没有相关性。普通用户和“专业”用户在检索术语的设计使用、匹配性程度的差异是导致搜索结果相关性高低不同的主要原因。这也说明了搜索引擎界面设计必需提供检索术语选择和使用运算符的重要性
[Abstract]:The traditional view is that if the search term contains more terms related to the topic and the Boolean logic operator is used to enhance the interpretation of the search word, the information retrieval system will also produce more relevant results. Although some studies show that ordinary Web search engine users rarely type search terms and Boolean logic operators, this does not mean that search results and retrieval terms are not related to the use of Boolean logic operators. The difference in the degree of matching between ordinary users and "professional" users in the design and use of retrieval terms is the main reason for the difference in the relevance of search results. This also illustrates the importance of search engine interface design to provide search term selection and the use of operators
