Abstract： In order to extract user requirements effectively in the field of car styling intelligent design, a method for extracting car styling requirements based on multi-feature TFIDF(word frequency-inverse file frequency) text analysis is proposed. Firstly, a large number of unregistered professional vocabularies is obtained through mutual information and boundary degrees of freedom to optimize the vocabulary after simple word segmentation. Next, in order to solve the problem of the limitations of the classic TFIDF algorithm, vocabulary and emotional feature factors are introduced to get user demand feature candidates set. Finally, effective user needs are obtained according to the threshold. The experimental results show that the multi-feature TFIDF text analysis algorithm has certain advantages in feature extraction, and can effectively extract user needs of the car styling in the text.
