This research will focus on feature extraction from requirements or textual descriptions of products in domain analysis. Extract the descriptors from requirements or textual descriptions of products. Then, descriptors are transformed into vectors and form a word vector space. Based on clustering algorithm, a set of descriptors are clustered into features. Their relationships will be inferred. Design the simulation experiment of feature extraction from natural language documents of products to prove that it can handle feature-extracting in terms of machine learning techniques.
