Embodiment
[0059] The present embodiment provides a Chinese word segmentation method based on bidirectional LSTM, CNN and CRF, the flow chart of the method is as follows figure 1 shown, including the following steps:
[0060] step one:
[0061] The initial corpus is preprocessed to extract single character information as the character feature information of the corpus, and the corresponding characters are converted into pinyin form as the pinyin feature information of the corpus. Annotate the text, get the labeled text and construct the character table, alphabet and label annotation table.
[0062] In this step, we use the BMEO annotation set to annotate the text, that is, the annotation set contains {B, M, E, O}, and the following characters form a word and itself is the first character, we mark it as B. The character in the middle of the word is marked as M. Characters at the end of words, marked as E. For a single character that does not form a word before and after, we mark it as...
