如何在Watson Conversation中从实体提取同义词值

Question

I need to extract all the synonym values for a particular entity. For example, I have an entity named Vehicle with values Car and Bus . For Car I have three synonyms, Mercedes , Volvo and Audi . Now what I need is when the entity Vehicle is detected in the user input for a value Car , I want to extract all the three synonym values present for Car . I know @Vehicle.literal will return the exact synonym value detected in the user input. But how can I retrieve all the synonyms for a particular entity value?

Answer 1

You can use the Conversation API to get information on an entity and its metadata . That information is not available in a dialog context itself.

IMHO a better way would be to use a database or similar to match up the detected entity with a list of synonyms. Usually, Conversation service is not used on its own, but part of a solution. The app server could perform the lookup if flagged. Take a look at the dialog actions for that. Or this suggestion on using the method of replaced markers in an answer .

基本上，您不能提取同义词。yiu可以做的一件事是创建另一个实体，该实体的值是您的汽车名称，同义词是车辆。因此，每当输入车辆时，它就会为您提供所有实体值。
