摘要：Passage-level natural language processing has received increasing attentions in recent years. This paper addresses the problem of passage intention classification for agricultural prescription documents. The proposed approach is based on supervised learning. In order to give a simple yet effective representation for passages in agricultural prescription documents, we augment the traditional Vector Space Model (VSM) widely used in text mining by 2-gram features. Besides, a set of third-party features with priori high class-discriminability are extracted using a third-party resource. We give comprehensive experimental comparisons of various learning algorithms and feature combinations using real world data set. The experimental results indicate that our approach offers promising classification performance. Copyright © 2014 Binary Information Press.
