Title Extraction of Daily Changing Words for Question Answering
Authors Kugatsu Sadamitsu, Ryuichiro Higashinaka and Yoshihiro Matsuo
Abstract This paper proposes a method for extracting Daily Changing Words (DCWs), words that indicate which questions are real-time dependent. Our approach is based on two types of template matching using time and named entity slots from large size corpora and adding simple filtering methods from news corpora. Extracted DCWs are utilized for detecting and sorting real-time dependent questions. Experiments confirm that our DCW method achieves higher accuracy in detecting real-time dependent questions than existing word classes and a simple supervised machine learning approach.
