DBpedia has begun an Evaluation Campaign with the aim of "evaluating DBpedia resources in order to assess and thereby improve the quality of DBpedia." It works like this: "First, please authenticate yourself with a google account. This will not only help prevent spam but also help us keep track of how many resources you evaluated. After you click 'Start', you will be provided with a list of classes from DBpedia wherein you may choose the ones you are most familiar with. There are three options: (1) Any: where a completely random resource will be retrieved, (2) Class: where you have the option to choose any class from the DBpedia ontology and a random resource belonging to that class will be retrieved, (3) Manual: where you can manually put in the DBpedia URI of a resource of your choice."
The instructions continue, "After selecting a resource, you will be shown each triple belonging to that resource on a single row. You need to look at each triple and evaluate whether it contains an error or not. If it contains an error, check the box 'has error'. Then, you need to choose an error type from a list. If the error type does not match any of the existing types, you have the option to provide a new type...Optionally, you may also write the correct form of the triple..."
