语言理解智能服务（LUIS）将于 2026 年 3 月 31 日完全停用。 LUIS 资源创建不可用。 从 2025 年 10 月 31 日开始，LUIS 门户将不再可用。 建议将 LUIS 应用程序迁移到对话语言理解，以便从持续的产品支持和多语言功能中受益。
keyPhrase 实体从话语中提取各种关键短语。 不需要将包含 keyPhrase 的示例话语添加到应用程序。 The keyPhrase entity is supported in many cultures as part of the Language service features.
预构建 keyPhrase 实体的解析
查询返回以下实体对象：
where is the educational requirements form for the development and engineering group
以下 JSON 的 verbose 参数设置为 false：
"entities": {
"keyPhrase": [
"educational requirements",
"development"
]
}
以下 JSON 的 verbose 参数设置为 true：
"entities": {
"keyPhrase": [
"educational requirements",
"development"
],
"$instance": {
"keyPhrase": [
{
"type": "builtin.keyPhrase",
"text": "educational requirements",
"startIndex": 13,
"length": 24,
"modelTypeId": 2,
"modelType": "Prebuilt Entity Extractor",
"recognitionSources": [
"model"
]
},
{
"type": "builtin.keyPhrase",
"text": "development",
"startIndex": 51,
"length": 11,
"modelTypeId": 2,
"modelType": "Prebuilt Entity Extractor",
"recognitionSources": [
"model"
]
}
]
}
}
The following example shows the resolution of the builtin.keyPhrase entity.
"entities": [
{
"entity": "development",
"type": "builtin.keyPhrase",
"startIndex": 51,
"endIndex": 61
},
{
"entity": "educational requirements",
"type": "builtin.keyPhrase",
"startIndex": 13,
"endIndex": 36
}
]
