Queries metadata in a dataset by inputting natural language.
Operation description
注意事项
-
请确保在使用该接口前,已充分了解智能媒体管理产品的收费方式和价格。该接口每次请求,会产生语义理解费用和查询费用两种计费项各一次。
-
调用该接口前,请确保您已通过绑定方式( CreateBinding )或者主动索引( IndexFileMeta 或者 BatchIndexFileMeta )方式将文件索引到数据集(Dataset)中。
-
返回结果仅为示例,根据工作流模板配置不同,获取到的文件元数据信息的类别和包含的内容均有可能与示例不同。如果有疑问,请加入钉钉群进行反馈,钉钉群号请参见联系我们。
使用限制
-
每次查询最多返回 100 个文件信息。
-
不支持翻页查询。
-
自然语言理解不保证完全准确。
-
该功能在美国(硅谷),美国(弗吉尼亚)地域下不支持。
使用方式
使用自然语言关键词对数据集内的文件进行搜索查询。目前支持理解的关键信息包括标签(Labels.LabelName)、时间(ProduceTime)和地点(Address.AddressLine)等。例如,以2023 年杭州的风景为条件进行查询,会被智能拆分为如下三个条件,并查找出同时满足这些条件的文件:
-
ProduceTime:2023 年 1 月 1 日零点起到 2023 年 12 月 31 日结束止
-
Address.AddressLine:包含
杭州关键词 -
Labels.LabelName:包含
风景标签
配合工作流模板配置,当模板中包含ImageEmbeddingExtraction算子时,该搜索请求会提供基于图片内容的搜索,即您输入的Query内容会同时被理解为图片内包含的内容,从而实现对图片的智能检索。
