Automatic Extraction of Linguistic Data from Digitized Documents

Terrence Szymanski
2013 Proceedings of the annual meeting of the Berkeley Linguistics Society  
In lieu of an abstract, here is a brief excerpt:This paper presents a system for automatically extracting linguistic data from digitized linguistic documents using a combination of existing software packages  ...  The system is designed to leverage existing resources in online digital libraries in order to bootstrap the creation of large, multi-lingual linguistic corpora, which can then be used to conduct data-driven  ...  In order to evaluate the feasibility of this approach, we conducted an experiment on a controlled parallel corpus taken from the Tatoeba database.  ...

OCR based slide retrieval

N. Daddaoua, J.M. Odobez, A. Vinciarelli

Retrieval experiments performed on a corpus of 570 slides (26 presentations) gathered at a workshop show that performance obtained with the OCR transcriptions are close to those obtained by extracting  ...  Since the most suitable acquisition technique, in such a context, is the use of a framegrabber (a device capturing as images the slides displayed on a screen), the slides must be transcribed with an Optical  ...  The text result is selected from all the generated hypotheses based on a confidence value computed for each recognized string based on langage modeling and OCR recognition statistics.  ...

Document Image Quality Assessment: A Brief Survey

Peng Ye, David Doermann
2013 2013 12th International Conference on Document Analysis and Recognition  
This paper provides a brief survey of research on the topic of document image quality assessment. We first present a detailed analysis of the types and sources of document degradations.  ...  of degradations and develop reliable methods for estimating the levels of degradations.  ...  When the consumer of a document image is machine, OCR software for example, document image quality may be defined as the OCR accuracy and DIQA metrics are factors that can be used to reliably predict OCR  ...

A survey on Arabic character segmentation

Yasser M. Alginahi
2012 International Journal on Document Analysis and Recognition  
This is due to both the cursive nature of Arabic writing in both printed and handwritten forms and the scarcity of Arabic databases and dictionaries.  ...  This survey presents the description of the Arabic script characteristics with an overview on OCR systems and a comprehensive review mainly on off-line printed Arabic character segmentation techniques.  ...  To the best knowledge of the author, very few references are available which provide some evaluation of Arabic OCR software.  ...

Extensible System for Optical Character Recognition of Maintenance Documents

John Anthony Labarga, Amardeep Singh, Vera Zaychik Moffitt
2018 Proceedings of the Annual Conference of the Prognostics and Health Management Society, PHM  
In the course of maintenance and operations, equipment operators and manufacturers frequently generate large volumes of paper documents.  ...  To implement analytics or automated monitoring, these documents must later be converted to digital copies, which can be ingested into a database.  ...  This generally requires scanning a document to produce an image, using OCR to produce a digital copy of the text, in an appropriate format for a database.  ...

AutoDBT: A Framework for Automatic Testing of Web Database Applications [chapter]

Lihua Ran, Curtis E. Dyreson, Anneliese Andrews
2004 Lecture Notes in Computer Science  
AutoDBT uses the model along with the test criteria to generate test cases for functional testing of the application.  ...  AutoDBT automatically generates a guard query for each test case. The guard determines whether the test can be performed given the current state of the database.  ...  In particular they show how to quickly generate, in parallel, a large database that obeys certain statistical properties among the records generated.  ...

Does Removing Pooling Layers from Convolutional Neural Networks Improve Results?

Claudio Filipi Goncalves dos Santos, Thierry Pinheiro Moreira, Danilo Colombo, João Paulo Papa
2020 SN Computer Science  
In this context, there is a trend already in motion to replace convolutional pooling layers for a stride operation in the previous layer to save time.  ...  In this work, we evaluate the speedup of such an approach and how it trades off with accuracy loss in multiple computer vision domains, deep neural architectures, and datasets.  ...  On behalf of all authors, the corresponding author states that there is no conflict of interest.  ...

2020 Electronics  
Although each article contains a brief introduction to the topic, there is a lack of work that would summarize the theoretical framework and provide an overview of the approaches developed so far.  ...  The survey describes selected approaches in a common theoretical framework based on Shannon's noisy channel. A separate section describes evaluation methods and benchmarks.  ...  The two following evaluation methodologies are used to evaluate spelling: • Mean reciprocal rank: A statistical measure for evaluating any process that produces a list of possible responses to a sample  ...

Information Retrieval Based on OCR Errors in Scanned Documents

Y. Fataicha, M. Cheriet, J. Y. Nie, C. Y. Suen
2003 2003 Conference on Computer Vision and Pattern Recognition Workshop  
The proposed algorithm consists of two basic steps. In the first step, we apply editing operations on OCR words that generate a collection of error-grams and correction rules.  ...  In this paper, we describe an approach that integrates the detection of errors in scanned texts without relying on a lexicon, and this detection is integrated in the research process.  ...  For example, if the word "light" is a term query, it is statistically uncertain because OCR confuses "i" with "l" and "c" with "e" etc. Thus, we generate 32 words.  ...
