The conditional nature of the distribution over label sequence can depend on non-independent, interacting features of the observation sequence. CRFs offer a solution to the problems in Chinese shallow parsing with hidden Markov models or with maximum entropy Markov models. First, as HMMs are generative, it is hard to employ overlapping features and nonindependent features of the inputs such as surrounding words.

通过单个状态将增大的或减小的概率和传递到它们的后继状态，使得这个单一的分布不需要对每个状态进行归一化，整个状态序列可以一起描述，从而克服了HMMs和 MEMMs的标记偏差（1abel bias）问题，而标记偏差的问题在汉语浅层分析中是个严重的问题。
