Embodiment 1
[0040] Embodiment 1: as Figure 1-3 As shown, a Lao language named entity recognition method based on improved Transformer+CRF, the specific steps are as follows:
[0041] Step1, preprocess the existing Lao language named entity corpus and divide the data set, in which the training set accounts for 90% and the test set accounts for 10%.
[0042] Step2, segment the Lao sentence, and pre-train the word vector through Gensim's word2vec model, and train the word vector with contextual semantics.
[0043] Step3, take the single character of each word after the word segmentation of the Lao sentence as input, and use Transformer as the character encoder to output the character-level feature vector.
[0044] Step4, splicing character-level feature vectors and word vectors trained in Step2 to form word embeddings.
[0045] Step5, perform position encoding on the word embedding (word embedding) obtained in Step4, and combine a position vector representing position information on the w...
