Example use cases

“I have a big batch of social media posts and I need you to pull out every @mention from this text so I can see who's being tagged: 'Great collab between @nike and @adidas today, shoutout to @runnerscommunity for the event coverage!'”
News article entity reference extraction
“Here's a news article — can you find and list all the mentions of people, brands, or organizations referenced in it? The article is about 3,000 words long.”
Community forum moderation tagging
“I need to know everyone who was mentioned or tagged in this forum thread so I can notify them. Here's the full thread text — please extract every mention you find.”
