Abstract

Document digitization in academic field enables us to apply automatic linguistic analysis to a large volume of academic papers. While current implementations of retrieval systems is mainly based on naive and shallow keyword extraction techniques, more advanced systems may leverage deeper linguistic analysis to help users easily access necessary papers or gain overview of a particular research field. In this paper, we first give a brief introduction to major natural language processing tasks targeting academic papers. Next, we describe methods for extracting natural language sentences and technical terms from digitized academic papers, with their difficulties and possible applications for each method.
