能否接入本地GraphDB内容以增强GraphDB实体链接功能?

问题

我已成功运行Ontotext文档提供的脚本,但当前仅支持Wikidata与DBpedia知识库。请问是否可通过接入本地GraphDB内容来扩充知识库,实现自定义实体的链接?

脚本来源

创建TAG客户端

PREFIX txtm: <http://www.ontotext.com/textmining#>
PREFIX txtm-inst: <http://www.ontotext.com/textmining/instance#>
INSERT DATA {
    txtm-inst:tagService txtm:connect txtm:Ces;
                    txtm:service "https://tag.ontotext.com/extractor-en/extract" .
}

通过GraphDB查找Tag实体

PREFIX txtm: <http://www.ontotext.com/textmining#>
PREFIX txtm-inst: <http://www.ontotext.com/textmining/instance#>
PREFIX pubo: <http://ontology.ontotext.com/publishing#>
SELECT ?annotationText ?annotationType ?annotationStart ?annotationEnd ?feature ?value
WHERE {
    ?searchDocument a txtm-inst:tagService;
                       txtm:text '''Dyson Ltd. plans to hire 450 people globally, with 
more than half the recruits in its headquarters in Singapore.
The company best known for its vacuum cleaners and hand dryers will add 250 engineers in 
the city-state. This comes short before the founder James Dyson announced he is moving 
back to the UK after moving residency to Singapore. Dyson, a prominent Brexit supporter 
who is worth US$29 billion, faced criticism from British lawmakers for relocating his 
company.''' .
    graph txtm-inst:tagService {
        ?annotatedDocument txtm:annotations ?annotation .
        ?annotation txtm:annotationText ?annotationText ;
                txtm:annotationType ?annotationType ;
                txtm:annotationStart ?annotationStart ;
                txtm:annotationEnd ?annotationEnd ;
                {
            ?annotation txtm:features ?item .
            ?item ?feature ?value
        }
    }
}
回答

完全可以接入本地GraphDB内容来扩充知识库,实现自定义实体链接,核心操作步骤如下:

  • 部署本地TAG服务:Ontotext的TAG(Text Analytics Generator)支持对接私有GraphDB知识库,你需要在本地或私有环境部署TAG服务,配置它指向你的GraphDB仓库,确保服务能访问仓库内的实体数据(包括实体标签、同义词、描述等用于文本匹配的属性)。
  • 修改客户端连接配置:替换原脚本中的官方服务端点,改为指向你本地部署的TAG服务地址。比如把txtm:service "https://tag.ontotext.com/extractor-en/extract"替换为你的本地服务URL(示例:http://localhost:8080/extractor-en/extract)。
  • 优化知识库数据:为本地GraphDB中的实体补充必要的文本属性(如rdfs:label、skos:prefLabel、skos:altLabel等),这能提升实体链接的匹配准确率,让TAG服务更好地将文本术语关联到自定义实体。

完成上述配置后,运行查询脚本时,TAG服务会优先从你的本地GraphDB知识库中匹配实体,实现自定义实体的链接功能。
