Part-of-speech tagging system, part-of-speech tagging model training apparatus and method

摘要

The invention relates to a part-or-speech tagging system, which comprises a part-or-speech tagging training model, and a part-or-speech tagging device, wherein the part-or-speech tagging training model is used for training the part-or-speech tagging model lay by layer and node by node by using tagged first texts in a part-or-speech tagging training set based on a part-or-speech hierarchy tree; and the hierarchy tree device is used for tagging part-or-speech of the texts to be tagged by using the trained part-or-speech tagging . The invention also relates to a part-or-speech tagging method, and a device and a method thereof for training the part-or-speech tagging model. According to the system and the method of the invention, the part of speech in a large scale part-or-speech tagging set is tagged, and the tagging precision of part of speech is enhanced.
