我注意到我们可以使用Watson EntityType从用户输入中提取time reference，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>
我试图弄清楚如何使用其他（支持的？）EntityTypes，例如Generic，Location，Amount等。但结果有时会出乎意料。例如＆＃34;在科罗拉多州丹佛的好房子＆＃34; for Location实体结果为＆＃34; nice＆＃34 ;;或指定＆＃34;昨天＆＃34;日期导致日期不正确。

我不确定我是否以the sample tutorial仅提及{ProfVar.value:main} or {ProfVar.value:name}的正确方式使用它。我在官方文档中找不到FROM_TIME FROM_DATE和DATE_TIME_RANGE。
支持哪些实体类型，如何在Watson Dialog中正确提取实体特定信息？
答案 0 :(得分：0)
我试图弄清楚如何使用其他（支持的？）EntityTypes，如Generic，Location，Amount等。但结果有时会出乎意料。例如＆＃34;在科罗拉多州丹佛的好房子＆＃34; for Location实体结果为＆＃34; nice＆＃34 ;;或指定＆＃34;昨天＆＃34;日期导致日期不正确。
＆＃34;尼斯＆＃34;是法国的城市。所以它给出了正确的答案。
问题是Dialogs实体提取是非常基本的。来自您的样本：
$ (LOCATION)={var-param_location}
这将找到第一个实体并停止寻找。为了证明这种限制，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，它将开始变得凌乱。它实际上仅适用于您期望返回一个实体或显式数量的实体的位置。
如果您想获得更准确的实体/关键字提取，请先将其发送到AlchemyAPI之类的内容。让API返回关键字/实体，然后使用它们。
