Summary
This paper investigates a new semi-supervised learning method that addresses the problem of NE chunking and syntactic chunking.
To utilize the unlabeled data, they created numerous auxiliary problems related to the target task and train classifiers for each of those. Then they learn the common predictive structure shared by those problems. The authors argued that such common structure can be used to improve the result of target task. One example of such auxiliary problem is: predict whether a word is "IBM" or not from its context. This is related to NE chunking since knowing a word is "IBM" helps to predict whether its part of a name.
