摘要
为了让普通用户也能利用本体知识库来解决问题,提升本体知识库检索的灵活性和改进查询效率.结合本体知识库固有的特征,给出了查询系统的框架和处理过程,并对系统中关键的技术和算法进行描述.提出了基于WordNet的本体词汇扩展和查询三元组映射算法.通过实验,验证了该方法的有效性.
To allow ordinary users to utilize ontology- based knowledge base (KB) to solve the problem, upgrade the flexibility of ontology - based KB search and improve the queries' efficiency. Combined with the inherent characteristics of ontology- based KB, given the query system framework and handling processes, and describe critical techniques and algorithms in systems. Proposed the expansion of the ontology vocabulary based on WordNet and query triples mapping algorithm. Verify the effectiveness of the method through experiments in this paper.
