TERMS: Text Extraction from Redundant and Multiple Sources
… are referenced in different formats (e.g. textual documents, web pages, database records, ontologies etc.). Identity resolution aims at creating a single view into the data where different facts are interlinked and incompleteness is remedied. We propose a four-step approach that starts with …

Text Extraction From Natural Scene: Methodology And Application
… Most of these applications can benefit from text information extraction in natural scene. However, scene text extraction is a challenging problem to be solved, due to cluttered background of natural scene and multiple patterns of scene text itself. To solve these problems, this dissertation …

Text Analytics to Inform Deviation Root Cause Analysis in Biomanufacturing
… processing tools to derive information from text describing deviations and causal factors. Several methods are explored, namely, unsupervised clustering using machine learning and natural language processing to identify and cluster similar causal factors, explicit text extraction which …

Scene Text Localization and Recognition for Images of Serial Numbers and Odometer Readings
… models and methods to create a full scene text extraction system. The system is composed of two main parts, a localization network and a recognition network, with the recognition network being the main focus. The localization network is a segmentation network that localizes the region in an …

Artificial Neural Networks-Driven High Precision Tabular Information Extraction from Datasheets
… manufacturing. A generalized solution for table text extraction would have to handle the variations in the page content and table layouts in order to accurately extract the text. We hypothesize that a table text extraction pipeline can extract this data in three stages. The first stage would …

Categorisation of sexual reproductive health short messages texts into thematic areas using text mining (a case study for the Zambia u-report).
… and access remote counseling services. This free texting program is run by the National HIV/AIDS/STI/TB Council supported by UNICEF. Millions of messages have been exchanged, but categorizing them manually to see what topics adolescents frequently ask about is challenging. This research explored …

Automated understanding of data visualizations
… (graph, chart, infographic, etc.), they read the text and process the images to quickly understand the communicated message. This research works toward emulating this ability in computers. In pursuing this goal, we have explored three primary research objectives: 1) extracting and ranking the most …

Prioritized text spotting using SLAM
… observations to achieve efficient and effective text detection and decoding for a sensor suite moving through an environment rich in text at a variety of scales and orientations with respect to the observer. We use simultaneous localization and mapping (SLAM) to isolate planar "tiles" …

Building CTRnet Digital Library Services using Archive-It and LucidWorks Big Data Software
… Big Data (LWBD) software, we take advantage of text extraction, clustering, similarity, annotation, and indexing services and build digital libraries with the generated metadata that will be helpful for the system stakeholders to locate information about an event. Through this study, we …

An investigation into the efficacy of URL content filtering systems
… the efficacy of the content filter. Using text extraction and pattern matching techniques to look for evidence of access to restricted content within this study, the results demonstrate that the belief that content filtering systems reliably prevent access to restricted content is …

Extracting generic text information from images
As a vast amount of text appears everywhere, including natural scene, web pages and videos, text becomes very important information for different applications. Extracting text information from images and video frames is the first step of applying them to a specific application and this task is …

Extracting Coronary Lesion Information from Angiogram Reports for Patient Screening Applications
… echocardiogram reports. The ejection fraction extraction task has been solved with regular expressions, a simple and somewhat inflexible pattern-matching approach. Our coronary lesion extraction followed a two-step general architectural approach that is common in NLP (Named Entity Recognition …
