基于关系数据库关键词查询的评分函数研究

Score Function Research Based on the Relational Database Keyword Query

为了解决目前关系数据库关键词查询效果不理想的问题,通过优化传统信息搜索领域的评分函数中的关键因子,提出了一种新的评分函数。通过实际数据分析验证该新的评分函数合理、有效。

This paper puts forward a new score function, by optimizing the key factors in the scoring function of the traditional information search field, jn order to solve the problem that the current relational database query result is not satisfactory. We verify the new score function reasonably and effectively through the actual data analysis.
