Lovers of language and literature, this is the place where you can work together to improve future generations of language technology. By indicating relationships between words and phrases you will help to create a resource that is rich in linguistic information.

Don't worry if you spend hours playing this game - you'll be doing it in the name of Science.
Quick instructions
When you play Phrase Detectives you will be asked your opinion of how phrases in texts (both fiction and non-fiction) refer to each other. This is done in two game styles:

You will be shown a text with a phrase highlighted in orange. You will be asked if this phrase refers to an entity (person, or other object) that has already been mentioned in the text. For example, you might see:

Sherlink Holmes went to the shop. He got some tobacco for his pipe.

In this example, the phrase in orange, He, refers to the same person as the phrase "Sherlink Holmes" in the previous sentence. In such cases, you should click on the earlier phrase and then on the Done button.

However, not all phrases refer to a previously mentioned things. In the text above, for instance, the phrases "some tobacco" and "his pipe" in the second sentence refer to objects not mentioned in the previous sentence. In these cases you should click the Not mentioned before button.

You will be asked whether you agree with another detective's decision. An example of this might be:

Sherlink Holmes went to the shop. He couldn't believe it was closed.

If you think that the word in orange, It, refers to the same object as the phrase in blue, the shop, you should say that you agree with this decision.

How the game works

We're back! The geeks have been working hard to produce a new version of Phrase Detectives that takes the best bits of the Facebook version (RIP) and updates the original game. Phrase Detectives version 2 may have a few teething problems as players are integrated over so get in contact is something odd happens and we'll get it fixed.

The team met up at Queen Mary University to discuss progress of Year 2 in the DALI project. Some of our goals are well ahead, which is great news.
