Automatic Detection of Pseudocodes in Scholarly Documents Using Machine Learning

Abstract—A significant number of scholarly articles in com-puter science and other disciplines contain algorithms that provide concise descriptions for solving a wide variety of compu-tational problems. For example, Dijkstra’s algorithm describes how to find the shortest paths between two nodes in a graph. Automatic identification and extraction of these algorithms from scholarly digital documents would enable automatic algorithm indexing, searching, analysis and discovery. An algorithm search engine, which identifies pseudocodes in scholarly documents and makes them searchable, has been implemented as a part of the CiteSeerX suite. Here, we illustrate the limitations of start-of-the-art rule based pseudocode detection approach, and present a novel set of machine learning based techniques that extend previous methods. I
