I am training a new entity `FULL_NAME` which would detect full names in texts, but I have a problem deciding what would be the correct way to handle names insides the addresses e.g. “ **Albert Einstein** DD _David Murray_ John Tower, Swindon, Wiltshire United Kingdom”, here I know that Albert Einstein is the person himself and David Murray is part of address and not a `FULL_NAME` in this context (according to my definition of full name).

- What I am afraid of is that if the model will be able to learn the difference or the boundary of “it’s a full\_name or not” here is too fuzzy"?
- If I choose to accept _David Murray_ as a `FULL_NAME`, with the idea that letter I could remove it with some rule-based approach, is it a problem that I have another entity `ADDRESS` which in this example would be:  
“DD David Murray John Tower, Swindon, Wiltshire United Kingdom”, and would overlap with the entity `FULL_NAME`?

I do think you’ll be making your task quite difficult if you distinguish names inside addresses like that. On the other hand, it’s true that you’ll get the overlap issue, so you wouldn’t be able to have the same model do the addresses and the names, if they overlap.

Have you considered annotating the elements of the address? So you would have subcategories like building, number, country etc. This might reduce the word-to-category ambiguity. The downside is it might take too much longer to annotate.

Hi @honnibal, thanks for the answer.

But again with this approach you would run into the same problem:

_"DD David Murray John Tower, Swindon, Wiltshire United Kingdom"_

is David Murray a person or a street name?

I think I might not understand the address myself, actually!

I thought `David Murray` was supposed to be the recipient? Or is it perhaps `David Murray John Tower`?

If `David Murray` is the recipient you’d mark it as `PERSON`. If it’s `David Murray John Tower`, you’d probability use the facility label, `FAC`.

I will try to explain it better this time:

_Albert Einstein DD David Murray John Tower, Swindon, Wiltshire United Kingdom_

How it should be processed is:

Albert Einstein ---\> PERSON  
DD David Murray John Tower, Swindon, Wiltshire United Kingdom ---\> ADDRESS

> If it’s `David Murray John Tower` , you’d probability use the facility label, `FAC`

Yes, this might be it...
