Annotating Tweets with Crowdflower

Overview of job

The primary purpose of this job is to help us identify tweets that talk about events that happen to people. What we mean by an event is someone who experiences something in life, so for example, having a child, going on holiday, going to the movies, starting school etc. A more formal definition would be: An event is something that someone experiences, at a particular time and location.

For each tweet you will be initially asked two questions. If you answer yes for the second question (Is the tweet about an event?), you willthen be asked a few more questions that are related to the event mentioned in the tweet.

Question Instructions

Is this tweet about [An Event Category]?

Firstly, we just want to know whether or not this tweet belongs to a particular category. This is a simple “Yes”, or “No” answer based on your best judgment.

Is this tweet about an event?

As previously mentioned, an “event” is something that happens to someone. So for example, having children, going on holiday, starting your first job, a bar mitzvah etc.


“I had a wonderful holiday in las vegas last week!” – This is tweet is about an event.

“Thomson Holidays is the best company ever”  – While the theme might be holidays, the tweet is not about an event as it’s an opinion.

Was the tweet tweeted before, during, or after the event?

We want to know when the tweet was made in respect to an event. So for example, is someone tweeting about an event that is going to happen, tweeting about an event that is currently happening, or tweeting about an event that happened in the past.


“I am going to get married next week”Before, as the tweet was made before the person got married.

“I just got married!”During, as the tweet indicates that the event has just happened

“Can’t believe it’s been a week since I got married”After, as the tweet indicates that the author got married a week ago.

Is the author of the tweet experiencing the event?

For this question, we want to know if whomever created the tweet is a participant in the event. So a bride might be tweeting about her upcomming wedding which means the author is involved in the event. However a friend might congratulate a couple on having a baby, where the author is not the one experiencing the event.


“I just got married”Yes, because the author is the one getting married.

“My sister got married”No, because it is the authors sister who got married.

Is anyone else named in the tweet experiencing the event with the author?

If the author was involved in the event, we are also interested to know if anyone else named in the tweet also experienced it.


“My wife and I got married”Yes, as the authors wife has been explicitly named in the tweet.

“I got married”No, as while the author probably got married to someone, the tweet does not say who.

Is anyone else named in the tweet experiencing the event?

If the author did not experience the event, then was anyone else named who experienced the event.


“My sister got married today”Yes, as the authors sister is getting married, while the author is not.

“There was a wedding ceremony at the local church today”No, as you don’t know any of the people who got married.

Did the event happen where the tweet was tweeted?

This question is about considering if you can tell if the tweet was created at the event. So for example, someone might tweet about how they are having a great time in las vegas. We could then assume from this example, where the event took place.


“What an awesome holiday this is! I can see St Pauls Cathedral from here”Yes, as we can reasonably assume that the person is tweeting while they are visiting London.

“Hope you and Dan have a wonderful wedding today. Shame I can’t be with you!”No, because we can see from this tweet that while Dan is having a wedding, the author is not at the wedding.

“Happy Birthday Samantha”Can’t Tell, because while Samantha is having a birthday the wording of the tweet gives us no indication as to whether or not the author is with Samantha on her birthday.
