|
|
Given text and a list of entity types, identify all entities of those types from the text.
|
|
|
|
-Steps-
|
|
1. Identify all entities. For each identified entity, extract the following information:
|
|
- entity_name: Name of the entity, capitalized
|
|
- entity_type: One of the following types: [organization, product, service, industry]
|
|
Format each entity as {"entity": <entity_name>, "entity_type": <entity_type>}
|
|
|
|
2. Return output in a single list with all the entities identified in steps 1.

10 co-brand partnerships in the US today and we are pleased that Visa has finalized a multi-year extension of

our successful credit co-branded partnership with Alaska Airlines, a portfolio that benefits from a loyal customer

base and high cross-border usage.
|
|
We have also had significant co-brand momentum in CEMEA. First, we launched a new co-brand card in partnership
|
|
with Qatar Airways, British Airways and the National Bank of Kuwait. Second, we expanded our strong global
|
|
Marriott relationship to launch Qatar's first hospitality co-branded card with Qatar Islamic Bank. Across the
|
|
United Arab Emirates, we now have exclusive agreements with all the leading airlines marked by a recent
|
|
agreement with Emirates Skywards.
|
|
And we also signed an inaugural Airline co-brand agreement in Morocco with Royal Air Maroc. Now newer digital

issuers are equally
