在Watson对话框中使用配置文件变量的实体类型

Question

我注意到我们可以使用Watson EntityType从用户输入中提取时间参考，例如：

<folder label="Invite Time">
                <output id="output_invite_time">
                    <prompt>
                        <item>What time is your meeting?</item>
                    </prompt>
                    <getUserInput>
                        <input>
                            <grammar>
                                <item>$ (DATE_TIME_RANGE)={var-invite_time}</item>
                            </grammar>
                            <action varName="var-invite_time" operator="SET_TO">{var-invite_time.value:FROM_TIME}</action>
                            <goto ref="output_invite_date"/>
                        </input>
                        <output>
                            <prompt>
                                <item>I'll need a valid time to continue.</item>
                            </prompt>
                            <goto ref="output_invite_time"/>
                        </output>
                    </getUserInput>
                </output>
            </folder>

我正试图弄清楚如何使用其他（支持的？）EntityType，如Generic、Location、Amount等。但结果有时出乎意料。例如，Location实体的"nice house in Denver，Colorado"会导致"nice"；或者指定"昨天"作为日期会导致日期不正确。

我不确定我是否以正确的方式使用它，因为示例教程只提到了{ProfVar.value:main} or {ProfVar.value:name}。我在官方文档中找不到DATE_TIME_RANGE的FROM_TIME和FROM_DATE。

支持哪些实体类型，如何在Watson对话框中正确提取特定于实体的信息？

Answer 1

我正试图弄清楚如何使用其他（支持的？）EntityType，如Generic、Location、Amount等。但结果有时出乎意料。例如，Location实体的"nice house in Denver，Colorado"会导致"nice"；或者指定"昨天"作为日期会导致日期不正确。

"尼斯"是法国的城市。所以它给出了正确的回应。

问题是Dialogs实体提取是非常基本的。来自您的样品：

$ (LOCATION)={var-param_location}

这将找到第一个实体并停止查找。为了演示这种限制，假设您希望在用户响应中获得三个可能的位置。

$ (LOCATION)={var-param_location}
$ (LOCATION)={var-param_location} (LOCATION)={var-param_location2}
$ (LOCATION)={var-param_location} * (LOCATION)={var-param_location2}
$ (LOCATION)={var-param_location} (LOCATION)={var-param_location2} (LOCATION)={var-param_location3}
$ (LOCATION)={var-param_location} * (LOCATION)={var-param_location2} (LOCATION)={var-param_location3}
$ (LOCATION)={var-param_location} * (LOCATION)={var-param_location2 * (LOCATION)={var-param_location3}
$ (LOCATION)={var-param_location} (LOCATION)={var-param_location2 * (LOCATION)={var-param_location3}

正如你所看到的，它会很快变得一团糟。它实际上只适用于您期望返回一个实体或明确数量的实体的情况。

如果你想获得更准确的实体/关键词提取，那么先把它发送到AlchemyAPI之类的地方。让API返回关键字/实体，然后使用它们。
