Title:
DEVICE FOR GENERATING TEXT CLASSIFICATION MODEL, METHOD, AND COMPUTER READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/200806
Kind Code:
A1
Abstract:
The present application discloses a device for generating a text classification model. The device comprises a memory and a processor. Stored in the memory is a model generation program executable on the processor. The following steps are performed when the program is executed by the processor: acquiring a word segmentation dictionary related to the field of finance and a text corpus related to the field of finance; selecting candidate new words from the text corpus, and adding the same to the word segmentation dictionary; acquiring a sample set, and performing class labeling on training samples in the sample set; and performing, on the basis of the word segmentation dictionary added with the candidate new words and by means of a pre-determined word segmentation algorithm, word segmentation on the training samples in the sample set, extracting word vectors, inputting, on the basis of an Adaboost algorithm, the word vectors and labeled class information into multiple weak classifiers for training, and obtaining a text classification model. The present application further provides a method for generating a text classification model, and a computer readable storage medium. The present application resolves the issue of a lack of sentiment orientation classification methods for text related to the field of finance in the prior art.
