Im wondering what is a good option to handle something like I need 2 rooms that can allow 6 people. Here 2 and 4 will be a “number” entities (extracted say by ner\_duckling\_http) but we need 2 slots populated for say number\_rooms and number\_people. ---

You need ner\_crf for this. Duckling can only extract the number but cannot contextualize it. It is similar to the probem of origin and destination. I want to fly to New york from LA. Both cities but in order to give it context, you need ner\_crf Read into CRF to understand how to tackle such problem. You will need many variations to training data. ---

Are you saying that ner\_crf can handle any number ?(It would not be feasible to give every possible number including text variations in training data) - it was my impression that duckling is needed for anything dealing with numbers/time etc. ---

Yeah duckling can handle numbers, but in your case you need more than numbers. Users says- I need 2 rooms that can allow 6 people Duckling will get you 2 and 6 as numbers which doesn’t help you contextualize it. You should train the CRF to get “2 rooms” and “6 people”. And use that to process the context. ---

You are not handling numbers with CRF rather context 2 rooms 5 people Basically to determine a pattern that essentially should follow a keyword (room,people,persons,guests) preceded by a number ---

So if I understand you correctly I should train the system to recognize the entities as normal and then use something else to say convert either the word two or the numeric 2 to 2 ? ---

Use the CRF to find 2 persons or 3 rooms and then you can use regex to find the number. Look into CRF a bit to tackle this kind of problem, it is not easy and your dataset should really be well balanced ---

Ok thank you for your suggestions ---

Hi, I have the same question but I think it’s a bit complicated: What if I need similar functionality, but not for English? Currently, we are using Tensor Flow pipeline as it’s language agnostic + translating Duckling, but as duckling just extracts everything it finds in the data, it won’t work in such situations. What approach should be taken in this situation? ---

@shota can you explain the problem or an example of your scenario
