Inheritance of custom entities from gold entities?

[Former Member]

Hello,

is it possible to inherit custom entities from gold entities?

Thanks in advance!

Hi Philipp,

We usually consider two steps in the analysis of entities:

• Detection
• Enrichment

The first one (detection) is relying on machine learning, where training examples are provided to an algorithm and make it learn what is/is not an entity, in which context it appears, etc. One way of making custom entities "inherit" from gold ones, would be to share this training across two datasets (the one we use to train gold entities, and the one you create to train custom entities).

The second one (enrichment), relies on parsing the detected entity value to make it actionable, where an algorithm is designed and used to handle a specific entity. Another way to inherit custom entities from gold entities, would be to apply the enrichment of a gold entity (e.g. #LOCATION), to a custom one (e.g. #LAKE).

Can you explain what you mean by making "custom entities inherit from gold entities"? What benefit do you expect?

Hello Paul,

thank you for your answer. Assuming the user says "I want to book a flight from New York to Chicago" and suppose there is a skill that wants to read the important information from it - then you need #LOCATION twice for the departure and destination. However, requesting this information in one skill at the same time causes the two pieces of information to be reversed under certain circumstances. However, you can not correct this behavior because gold entities can not be trained. So you need custom entities. For example, #LOCATION_DEPARTURE and #LOCATION_DESTINATION. However, these are not as knowledgeable then the gold entity #LOCATION. Therefore it would be useful if one could directly inherit custom entities from gold entities.

I hope that was understandable
