Abstract: Based on the abundant unstructured and unlabeled texts of consumer reviews in e-commerce websites, a two-view semi-supervised learning method is proposed to classify the reviews and identify the content related to product quality problems, so as to mine the hidden quality defects and dangers of products. Comprehensively considering the characteristics of vocabulary, emotion, domain and so on, the text view and non-text view are constructed, and the Co-training collaborative training algorithm is adopted to classify the reviews according to whether quality problems are involved. Taking the electric kettle as an example, the consumer reviews were crawled from an e-commerce website for empirical analysis. Results show that F1 score and AUC of the proposed method are 82.18% and 86.24%, respectively, which is significantly improved compared with the single view supervised learning classifier.

Key words: reviews classification, multi-view learning, semi-supervised learning, collaborative training, quality problems identification
