Metrics details. The absence of effective means to extract text from these PDF files in a layout-aware manner presents a significant challenge for developers of biomedical text mining or biocuration informatics systems that use published literature as an information source. Our paper describes the construction and performance of an open source system that extracts text blocks from PDF-formatted full-text research articles and classifies them into logical units based on rules that characterize specific sections. The LA-PDFText system focuses only on the textual content of the research articles and is meant as a baseline for further experiments into more advanced extraction methods that handle multi-modal content, such as images and graphs. The system works in a three-stage process: 1 Detecting contiguous text blocks using spatial layout processing to locate and identify blocks of contiguous text, 2 Classifying text blocks into rhetorical categories using a rule-based method and 3 Stitching classified text blocks together in the correct order resulting in the extraction of text from section-wise grouped blocks. We also present an evaluation of the accuracy of the block detection algorithm used in step 2. Finally, we discuss preliminary error analysis for our system and identify further areas of improvement.
