AB  - A large number of new words in product reviews generated by mobile terminals are valuable indicators of the privacy preferences of customers. By clustering
these privacy preferences, sufficient information can be collected to characterize users and provide a data basis for the research issues of privacy protection.
The widespread use of mobile clients shortens the string length of the comment corpus generated by product reviews, resulting in a high repetition rate.
Therefore, the effective and accurate recognition of new words is a problem that requires an urgent solution. Hence, in this paper, we propose a method
for discovering new words from product comments based on Mutual Information and improved Branch Entropy. Firstly, by calculating the Co-occurrence
Frequency and Mutual Information between words and adjacent words, the character strings of words after pre-processing and word segmentation are
expanded left and right respectively to discover the potential word set. The candidate set of new words is obtained by means of an improved support filtering
algorithm. Finally, a new word set is built by applying an improved Branch Entropy filtering algorithm and removing old words. The experimental results
show that this method can accurately and effectively identify new words in product comments.
