[目的/意义]构建国史知识检索平台,提高用户获取国史知识的效率,促进国史宣传和教育。[方法/过程]提出基于本体的国史知识检索平台构建思路与总体框架,在构建国史本体知识库的基础上,采用Neo4j数据库作为RDF数据仓储,创建基于Solr的实例索引、三元组索引和词条索引,针对多种检索需求设计实现检索引擎的执行流程、检索式构造方法以及查询处理算法,并为国史知识展示设计可视化实现方式。[结果/结论]构建国史知识检索平台,提供实体检索、查询问答、关联检索、时序检索及语义资源浏览等检索与浏览服务。该平台框架及关键技术实现方案可为面向领域知识的深度检索服务提供重要参考。
[Purpose / Significance] Constructing a platform for knowledge retrieval of Chinese history so as to enhance the efficiency of users in acquiring knowledge of Chinese history and promote publicity and education of Chinese history. [Methods / Processes] This paper proposes the construction idea and overall framework of ontology-based knowledge retrieval platform of national history. Based on constructing the knowledge base of ontology ontology, we use Neo4j database as RDF data repository to create Solr-based instance index, triple index and word Index for a variety of search needs to design and implementation of the search engine implementation process, search structure and query processing algorithms, and for the display of knowledge of the implementation of the national history of the way. [Results / Conclusion] Constructing a knowledge retrieval platform for Chinese history, providing search and browse services such as entity retrieval, querying and querying, relational retrieval, timing retrieval and semantic resource browsing. The platform framework and key technology solutions provide an important reference for deep search service for domain knowledge.
