• Title: Segmenting Messy Text: Detecting Boundaries in Text Derived from Historical Newspaper Images
• Authors: Carol Anderson and Phil Crone (Ancestry.com)
• Abstract summary: We consider a challenging text segmentation task: dividing newspaper marriage announcement lists into units of one announcement each. In many cases the information is not structured into sentences, and adjacent segments are not topically distinct from each other. We present a novel deep learning-based model for segmenting such text and show that it significantly outperforms an existing state-of-the-art method on our task.

• Abstract: Text segmentation, the task of dividing a document into sections, is often a prerequisite for performing additional natural language processing tasks. Existing text segmentation methods have typically been developed and tested using clean, narrative-style text with segments containing distinct topics. Here we consider a challenging text segmentation task: dividing newspaper marriage announcement lists into units of one announcement each. In many cases the information is not structured into sentences, and adjacent segments are not topically distinct from each other. In addition, the text of the announcements, which is derived from images of historical newspapers via optical character recognition, contains many typographical errors. As a result, these announcements are not amenable to segmentation with existing techniques. We present a novel deep learning-based model for segmenting such text and show that it significantly outperforms an existing state-of-the-art method on our task.

  This paper focuses on the more challenging task of artistic text segmentation and constructs a real artistic text segmentation dataset. We propose a decoder with the layer-wise momentum query to prevent the model from ignoring stroke regions of special shapes. We also propose a skeleton-assisted head to guide the model to focus on the global structure.

  This paper aims to learn a model capable of segmenting arbitrary visual concepts within images by using only image-text pairs without dense annotations. Existing methods have demonstrated that contrastive learning on image-text pairs effectively aligns visual segments with the meanings of texts. A text often consists of multiple semantic concepts, whereas semantic segmentation strives to create semantically homogeneous segments.

Our method was evaluated on four public benchmarks for referring image segmentation, where it clearly outperformed the existing method for the same task and recent open-vocabulary segmentation models on all the benchmarks.

  We present an unsupervised deep learning method that embeds document image patches to a compact Euclidean space where distances correspond to a coarse text line pattern similarity. Text line segmentation can be easily implemented using standard techniques with the embedded feature vectors. We evaluate the method qualitatively and quantitatively on several variants of text line segmentation datasets to demonstrate its effectivity.
