Abstract

The invention provides a traditional Chinese medicine clinical field word embedding learning method and a traditional Chinese medicine clinical field word embedding migration method based on migrationlearning, aiming at the field of low resources in the traditional Chinese medicine clinical field, a migration learning method is adopted, and data resources in the field of low resources are expanded based on instance migration learning. Trained model parameters can be reused based on transfer learning of parameter knowledge, and therefore the purposes of accelerating model training and saving training cost are achieved. And meanwhile, a sampling method is improved, and the problem that context words of the head words are not really close to the head words is solved by using global context random negative sampling based on the PPMI.

Description

technical field [0001] The invention relates to the field of natural language processing, in particular to a word embedding learning method and a migration method in the clinical field of traditional Chinese medicine based on migration learning. Background technique [0002] In the field of clinical medicine, the learning of word embeddings in the clinical field of traditional Chinese medicine is helpful for tasks such as data mining of clinical text data information in traditional Chinese medicine. Word embeddings in the clinical field of traditional Chinese medicine can also be applied to disease prediction, clinical event prediction, and medical concept elimination. Ambiguity and other research scenarios. Because of the privacy of clinical medical data, researchers cannot obtain large enough data to train high-quality word embeddings, and even lack of resources for training high-quality word embeddings. [0003] Since the clinical field of traditional Chinese medicine is...
