Local and Global Graph Modeling with Edge-weighted Graph Attention Network for Handwritten Mathematical Expression Recognition
Additionally, we propose a stroke-level Graph Modeling method for both local (LGM) and global (GGM) information, which applies an end-to-end model to Online HMER tasks, transforming the recognition problem into node and edge classification tasks in graph structure.
ColBERT's [MASK]-based Query Augmentation: Effects of Quadrupling the Query Input Length
We then examine the effect of changing the number of [MASK] tokens from zero to up to four times past the query input length used in training, both for first stage retrieval, and for scoring candidates, observing an initial decrease in performance with few [MASK]s, a large increase when enough [MASK]s are added to pad queries to an average length of 32, then a plateau in performance afterwards.
Mathematical Information Retrieval: Search and Question Answering
This book begins with a simple framework characterizing the information tasks that people and systems perform as we work to answer math-related questions.
A Study of PHOC Spatial Region Configurations for Math Formula Retrieval
A Pyramidal Histogram Of Characters (PHOC) represents the spatial location of symbols as binary vectors.
ChemScraper: Leveraging PDF Graphics Instructions for Molecular Diagram Parsing
Most molecular diagram parsers recover chemical structure from raster images (e. g., PNGs).
Optical Character Recognition
Optical Character Recognition (OCR)
Effects of context, complexity, and clustering on evaluation for math formula retrieval
There are now several test collections for the formula retrieval task, in which a system's goal is to identify useful mathematical formulae to show in response to a query posed as a formula.
ScanSSD: Scanning Single Shot Detector for Mathematical Formulas in PDF Document Images
We introduce the Scanning Single Shot Detector (ScanSSD) for locating math formulas offset from text and embedded in textlines.
Query Auto Completion for Math Formula Search
Query Auto Completion (QAC) is among the most appealing features of a web search engine.
A Text Detection System for Natural Scenes With Convolutional Feature Learning and Cascaded Classification
We propose a system that finds text in natural scenes using a variety of cues.
Detecting Figures and Part Labels in Patents: Competition-Based Development of Image Processing Algorithms
We report the findings of a month-long online competition in which participants developed algorithms for augmenting the digital version of patent documents published by the United States Patent and Trademark Office (USPTO).
