摘要
以经济学领域本体为例,首先研究SemSORD基本原理和方法,然后提出基于关系数据库关键词检索(Keyword Search over Relational Databases,KSORD)技术实现的关系数据库语义检索模型,并实现相应的原型系统Si-SEEKER,最后提出该领域的研究挑战和技术发展趋势.
Taking the economics ontology as an example,the authors study the principles and methods of SemSORD in detail and present a novel SemSORD prototype called Si-SEEKER based on keyword search over relational databases.In the end,the emerging research on SemSORD is proposed.
