An efficient framework to classify short text from scientific documents is proposed. Topic models from various types of knowledge were used for enhancing features in documents. Two methods were presented to optimize external features that enhance relatedness in documents. The performances were evaluated by using real-world scientific documents from online publisher. Proposed methods are shown to outperform related work.
