如何在LUIS和BOT框架中评估像Greater today这样的用户输入

Question

我正在建立一个机器人使用微软机器人框架在C#和路易斯。使用预先构建的实体datetime.V2，我能够正确地捕获“上周”、“下个月”等术语。然而，当涉及到以下内容时，我感到震惊：

 "Get me all products which has expiry life greater than 2 years",
 "greater than today",
 "> today" etc.,

我是否使用LUIS复合实体？如果是这样，"Greater than“和"today”是否会成为名为"DateComparer“的复合实体的子级？有没有什么github示例可以让我参考一下，以了解复合实体是如何解析的？

提前感谢您的帮助和时间。

我根据米斯科夫的建议创建了一个ComparerList。

  "composites": [
    {
      "name": "DateComparer",
      "children": [
        "ComparerList",
        "datetimeV2"
      ]
    }
  ],
  "closedLists": [
    {
      "name": "ComparerList",
      "subLists": [
        {
          "canonicalForm": "gt",
          "list": [
            "greater than",
            "larger than",
            "more than",
            "over",
            "exceeding",
            "higher than",
            ">"
          ]
        },
        {
          "canonicalForm": "lt",
          "list": [
            "<",
            "less than"
          ]
        },
        {
          "canonicalForm": "eq",
          "list": [
            "=",
            "equal to"
          ]
        },
        {
          "canonicalForm": "le",
          "list": [
            "<=",
            "less than or equal to"
          ]
        },
        {
          "canonicalForm": "ge",
          "list": [
            ">=",
            "greater than or equal to"
          ]
        }
      ]
    }
  ],
  "bing_entities": [
    "datetimeV2"
  ],

我能够训练Luis根据诸如“给我所有过期时间大于昨天的项目”之类的语句来返回以下json。在测试时，我得到了下面的json。

  "entities": [
    {
      "entity": "greater than",
      "type": "ComparerList",
      "startIndex": 33,
      "endIndex": 44,
      "resolution": {
        "values": [
          "gt"
        ]
      }
    },
    {
      "entity": "greater than yesterday",
      "type": "DateComparer",
      "startIndex": 33,
      "endIndex": 54,
      "score": 0.6950233
    },
    {
      "entity": "yesterday",
      "type": "builtin.datetimeV2.date",
      "startIndex": 46,
      "endIndex": 54,
      "resolution": {
        "values": [
          {
            "timex": "2017-09-14",
            "type": "date",
            "value": "2017-09-14"
          }
        ]
      }
    }

从这里，我检索"gt“解析并在代码中使用它。
