Instances (e.g., university of michigan at ann arbor, cadillac cts-v) and their class labels (universities, sport sedans) are basic building blocks towards the elusive goal of constructing knowledge resources automatically. Different Web users may refer to the same instances using different class labels at different levels of granularity. Consequently, efforts to represent knowledge about open-domain instances benefit from the acquisition of as many relevant class labels as possible. Class labels conveniently summarize the properties shared among the instances of each class. Finer-grained classes are more specific, their class labels capture more of the relevant properties associated with their instances, but they are more difficult to extract from textual data.
