OBJECTIVE We explored two strategies for query expansion utilizing medical subject headings (MeSH) ontology to improve the effectiveness of medical image retrieval systems. In order to achieve greater effectiveness in the expansion, the search text was analyzed to identify which terms were most amenable to being expanded. DESIGN To perform the expansions we utilized the hierarchical structure...

We propose a new approach for cross-cut shredded document reconstruction and evaluate it on the DARPA Shredder Challenge dataset. We begin by pre-processing chads. A set of costs based on shape (gaps, overlaps, edge similarity), graphical content (ruling line alignment, text line alignment), and semantic content (character and letter combinations) is calculated and used to rank putative chad ma...
