The word segmentation technology comprises three development stages of rule dictionary matching, statistical machine learning and deep learning. Matching based on the rule dictionary comprises forward maximum matching and reverse maximum matching bidirectional maximum matching; the statistical machine learning-based method comprises an n-element language model, a maximum entropy model, a conditional random field and the like; with mass data information generated in the stage of advancing web2.0 to web3.0, word segmentation methods based on deep learning are continuously started, and include a convolutional neural network, a cyclic neural network, a long-time memory network, a mode of combining with a conditional random field and the like, and a label mode adopted in the identification process is a BIO or BIOES label.
