Feature Selection for Document Retrieval in the Export Control Domain
Lecture Notes in Networks and Systems(2018)
摘要
It is difficult to classify electronic documents into strategic technology and non-strategic technology. A document retrieval system to find out similar cases efficiently has been developed. However, its performance should be improved as more documents are accumulating on the system. In this paper, we will apply feature selection method based on chi square and try to improve the performance of system.
