摘要
提出本体实体的语义标注策略。为验证此策略对于文档搜索结果的优化效果,借助于KIM平台,利用中华烹饪文化领域本体,首先将文档中实体与本体知识库中实例相互映射实现语义标注,接着通过索引用户查询条件与实例来实现语义查询,最后对结果进行测评,并融合关键词搜索结果对文档结果进行排序。研究表明基于本体的实体标注策略所达到的文档语义搜索能实现较良好的文档检索效果。
This paper proposes the strategy of entities label annotation based on Ontology. In order to verify the effectiveness of this strategy, by means of KIM platform, this paper uses Chinese cuisine culture domain Ontology as experimental data, mapping entities in document to the instances in Ontology knowledge base to achieve semantic annotation firstly, and then indexs the user query with instances to achieve the semantic retrieval. At last, the experimental results are evaluated. The study shows that the proposed strategy has a better performance on document retrieval.
