Abstract

In this paper, we selected the textual reviews of drugs on Ali Health Pharmacy as sample data. Firstly, the text was pre-processed, including data cleaning, word separation, lexical annotation and removal of deactivated words, in order to lay the data foundation for the subsequent analysis process. Secondly, we conducted semantic analysis on the processed review texts, including word frequency analysis, LDA topic clustering analysis and word frequency co-occurrence analysis. The results showed that the overall distribution of semantic features in the text content of initial and additional comments was similar, but there were differences in the attention of consumers to different topics in initial and additional comments.
