Show all documents The approach used confusion information for specific characters, along with bi-gram probabilities of character occurrences to create multiple possible search terms for each initial search term. After performing the search with each new term, the validity of returned documents is based on the confusion and bi-gram occurrence probabilities.

Document Recognition: OCR

The automated document analysis step is a key part of the overall document recognition process. During the document analysis step, the document is analyzed in regards to its logical structure — first and last document pages are identified, the formatting elements such as footnotes, headers, footers and table of content are detected. At the same time, the layout of each individual page is detected and each page is divided into individual objects, such as text blocks, pictures, tables and table cells, barcodes, and separators. Additionally, the document analysis algorithms detect page orientation, identifies double pages, detects vertical text and define page areas that are not relevant for the OCR process. As a result, the ABBYY FineReader Engine is able to specify text areas and fields that should be recognized and page areas, such as images or diagrams, that should be kept in their original form.

AI combines the latest in Deep Learning and AI, plus 20 years of document expertise, to teach machines how to understand your documents — saving time and money when it comes to data entry and data extraction. Most documents these days are digitally born and therefore contain rich semantic information beyond the document image. By combining this embedded information such as metadata, tags, display list order, Unicode and more with the latest in Deep Learning, PDFTron. AI achieves a better understanding and thus, a higher degree of accuracy compared to alternatives.

Comparing Approaches to Mathematical Document Analysis from PDF Abstract: Document analysis of mathematical texts is a challenging problem even for born-digital documents in standard formats. We present alternative approaches addressing this problem in the context of PDF documents. One uses an OCR approach for character recognition together with a virtual link network for structural analysis. The other uses direct extraction of symbol information from the PDF file with a two stage parser to extract layout and expression structures.
