Abstract

This paper describes our system created for the Financial Document Structure Extraction Shared Task (FinTOC-2019) Task A: Title Detection. We rely on the XML representation of the financial prospectuses for additional layout information about the text (font type, font size, etc.). Our constrained system uses only the provided training data without any additional external resources. Our system is based on the Maximum Entropy classifier and various features including font type and font size. Our system achieves F1 score 97.2% and is ranked #3 among 10 submitted systems.
